Aim of proficiency testingProficiency testing is defined in ISO/IEC 17043 as the evaluation of participant performance against pre-established criteria by means of interlaboratory comparisons. The term External Quality Assessment or EQA is often used for proficiency testing in the medical / clinical area.
LGC Standards provides a wide range of schemes designed to improve the quality of analytical testing and measurements in those sectors covered. The schemes involve the regular distribution of test materials in order for participants to test for defined parameters, and to have their results statistically analysed. Participation provides laboratories with a means of assessing the accuracy and comparability of their results with peer laboratories over time.
When performed within the context of a comprehensive quality assurance programme, proficiency testing is an independent means of assuring the quality of test and calibration results, as described in ISO/IEC 17025 and ISO 15189.
Quality standardsLGC Standards is committed to continual improvement in quality and efficiency through sound quality assurance procedures. This commitment is demonstrated through certification to ISO 9001 for all our activities. Our PT schemes are accredited by the United Kingdom Accreditation Services (UKAS) certificate number 0001 and operated in accordance with ISO/IEC 17043. For details of the accredited schemes, please refer to our scope of accreditation at: www.lgcstandards.com.
Please note that the AFPS, DAH, FIRMS and OIL PT schemes are currently not included.
Our proficiency testing services are supported by the scientific excellence of the LGC Group, the UK National Measurement Institute for analytical chemistry, as well as reference materials from LGC Standards, our market- leading manufacturing and distribution business.
Benefits of proficiency testing There are many benefits associated with participation in a proficiency testing scheme or external quality assessment. Key is the independent assessment of performance and the opportunity to compare your performance with peer laboratories, often on a global basis.
Other benefits include:
• Monitor the quality of measurements made and thereby identify improvements required• Greater process control• Demonstrate competency to customers, accreditation bodies and other regulatory bodies• Identify staff development and training needs• Compare methods or procedures

AFPS - Animal feed The Animal Feeds Proficiency Scheme (AFPS) is specifically designed to meet the needs of laboratories performing chemical or microbiological analysis of animal feedstuffs.
Animal feed quality is highly regulated since the majority of animals, or their products, will be converted into food for human consumption.
EC Regulation 767/2009 stipulates the requirements for the marketing and use of animal feeds, and (with reference to related regulations) requires complete traceability of feeds, personnel, and additives, and defines the compulsory labelling requirements. Measures must be taken to prevent contamination with hazardous materials above specified limits; such as heavy metals, mycotoxins, etc. and microorganisms capable of causing human disease (zoonotic agents) such as Salmonella species.
Major food safety crises can occur from the contamination of animal feed causing risks to animal and human health resulting in recalls; financial damage as large quantities of product have to be destroyed; and the potential for considerable damage to the reputation of any businesses involved. Recalls include melamine in pet foods, numerous events of animal feed cargo rejected due to aflatoxin contamination, pork products contaminated with dioxins, and many more. Preventing these issues through reliable analysis at source backed up by independent verification through participation in a proficiency scheme, can help to save large sums of money for a very small investment.
The full range and availability of test materials in AFPS is determined on an annual basis and further details can be found in the AFPS application form and scheme description.
Note: Test materials and analytes may be added or removed, please see current application form. AFPS is currently not included in our scope of accreditation.

QCS - ChocolateThe Quality in Chocolate Scheme (QCS) is intended for use by microbiologists and chemists working in the chocolate manufacturing industry.
Cacao trees were first cultivated by the Aztecs, who used the beans both as a form of currency and to produce a spiced drink known as ‘chocolatl’. Over the years, many different types and flavours of chocolate have been developed and cacao derivatives are often blended with other ingredients to produce a diverse range of products. Chocolate is probably the most popular end-product; in some countries up to 90 % of the population buys chocolate on a regular basis.
Chocolate products are also one of the few food commodities whose composition is controlled at EC level. For example, EC Directive 2000/36/EC ‘relating to cocoa and chocolate products intended for human consumption’, sets common rules and definitions with regard to the composition, manufacture, packaging and labelling of chocolate and cocoa products.
The full range and availability of test materials in QCS is determined on an annual basis and further details can be found in the QCS application form and scheme description.
Note: Test materials and analytes may be added or removed, please see current application form.

QDCS - Dairy chemistry The Quality in Dairy Chemistry Scheme (QDCS) is one of the most comprehensive proficiency testing scheme available to laboratories performing compositional and safety analysis in the dairy sector. EU Regulation 853/2004 introduces specific hygiene rules applying to raw milk and dairy products, including control of residual antibiotics.
When cattle ingest aflatoxins and other contaminants in feed, toxic metabolites can be formed and may potentially infect milk, cheese and other dairy products. For laboratories that perform the analysis of dairy produce using traditional ‘wet’ chemistry techniques, as well as determinations by infrared analysers, participation in a relevant proficiency testing scheme can provide confidence that results of these analyses are meaningful and accurate which, in turn, helps to ensure the safety of these products.
The full range and availability of test materials in QDCS is determined on an annual basis and further details can be found in the QDCS application form and scheme description.

QFCS - Food chemistryThe Quality in Food Chemistry Scheme (QFCS) is specifically designed to promote the quality and comparability in the measurement of a range of analytes in food products.
All kinds of foods are available worldwide and all year round, following years of research and advances in the logistics required. Technology now allows suppliers to harvest, preserve and distribute within a short period of time.
However, food quality, consumer satisfaction and government regulations are all issues that need to be taken into consideration with regards to global food trade. Testing these food products in the laboratory is fundamental for safety and stability with respect to microbial growth, chemical / bio-chemical composition, and physical properties.
The full range and availability of test materials in QFCS is determined on an annual basis and further details can be found in the QFCS application form and scheme description.

QGS - Gelatine The Quality in Gelatine Scheme (QGS) has been developed in collaboration with the trade body, Gelatine Manufacturers of Europe (GME). GME members account for nearly half of the worldwide gelatine production and the key role of the GME is to ensure that gelatine is manufactured to a consistently high quality for the benefit of gelatine customers and consumers.
Gelatine is a pure protein obtained from animal raw materials containing collagen and is typically produced in two grades as far as microbiological specification is concerned - food grade and pharmaceutical grade.
Gelatine is an excellent nutrient for most bacteria and for this reason the manufacturing processes have to avoid contamination, otherwise the safety and / or quality of the gelatine could be affected.
QGS test materials are available on a gelatine hydrolysate matrix in order to represent a realistic challenge, and include the relevant microorganisms for laboratories involved in the quality control analysis of gelatine.
The full range and availability of test materials in QGS is determined on an annual basis and further details can be found in the QGS application form and scheme description.
Note: Test materials and analytes may be added or removed, please see current application form.

Email: [email protected] Website: www.lgcstandards.com 17
QMAS - Meat and fishThe Quality in Meat and Fish Analysis Scheme (QMAS) is intended for use by chemists and microbiologists working in the meat, fish and shellfish processing industries. Legislation in the form of EU Regulation 882/2004 ‘Official Controls Performed to Ensure the Verification of Compliance with Feed and Food Law, Animal Health and Animal Welfare Rules’ requires official control laboratories to be accredited to ISO/IEC 17025 and therefore to use external means of monitoring performance such as proficiency testing.
A variety of real meat test materials in a vacuum packed and lyophilised vial format is provided for participants, enabling them to analyse a comprehensive range of relevant chemical test parameters which are all widely used in the meat sector. The real fish test material allows laboratories to perform a range of basic proximate and heavy metal analysis. The shellfish test material is provided for heavy metal analysis only.
Product authentication and speciation is a concern for the fish and meat industries. Our test materials will challenge laboratories carrying out analytical testing to determine the identity of these products and can help give authority to their results.
For microbiological determinations, test materials are provided in a lyophilised matrix for the analysis of indicator organisms, as performed routinely in factory based laboratories and third party testing facilities. There are also test materials for pathogen analysis suitable for laboratories permitted to undertake this analysis, often carried out by external providers.
The full range and availability of test materials in QMAS is determined on an annual basis and further details can be found in the QMAS application form and scheme description.

QMS - Food microbiologyThe Quality in Microbiology Scheme (QMS) is intended for use by microbiologists working in the food, beverage, dairy, herbs, spice and many other industries.
Food testing is an essential element of the ‘Hazard Analysis Critical Control Point’ (HACCP) process in food production as it verifies the controls are working at the critical points in manufacturing. Failures leading to food poisoning outbreaks can have a devastating effect on reputation, brand value and ultimately profits. Failures which do not lead to an outbreak also can have an effect, leading to reduced shelf life and wastage, or discernable product defects - affecting consumer confidence in the product.
Laboratories carrying out such microbiological testing need to be able to demonstrate that they are producing accurate and meaningful results. This can be done by conducting a comprehensive quality assurance programme, which includes regular participation in a suitable PT scheme.
The range of organisms offered for testing covers all those that are likely to be found, from spoilage organisms, pathogens, indicator organisms and normal background flora.
The full range and availability of test materials in QMS is determined on an annual basis and further details can be found in the QMS application form and scheme description.

“How often do I need to participate?”
“The frequency that a laboratory needs to participate in proficiency testing depends on a wide range of factors specific to each individual laboratory. Therefore every individual laboratory may have a different need, which is why our schemes provide flexible participation, although some do have a minimum participation level. Third parties, such as regulatory bodies, may recommend minimum levels of participation. To gain the benefit from trend analysis, participation in a minimum of four rounds over a scheme year is normally recommended.”

AIR PT - Workplace air, ambient air, indoor / chamber air and stack emissions The AIR Proficiency Testing scheme is a collaboration between LGC and the UK Health and Safety Laboratory (HSL). The AIR PT scheme is run by LGC and is supported by the technical expertise at HSL. The scheme combines HSL’s WASP and LGC’s STACKS schemes, providing an integrated scheme that is specifically designed for all laboratories undertaking analysis of samples derived from various fields of air monitoring.
A common approach to monitor air quality is to collect gaseous and particulate pollutants on to suitable sampling media and submit these to the laboratory for analysis. The aim of the AIR PT scheme is to support the quality of analytical data generated by laboratories performing chemical analysis of the samples taken.
The test materials in the AIR PT scheme may contain one or more analytes prepared at various concentrations on appropriate sampling media. They are prepared in such a way as to give a realistic test for the laboratory and a valuable means of monitoring analytical performance. The AIR PT scheme will support the quality of this analytical data generated by laboratories performing measurements on samples taken from, for example, ambient, indoor, stack and workplace air testing arenas.
Regular monitoring allows information to be collected, in order to review and assess air quality and ensure legislative standards are being met. It also helps to determine the effectiveness of control systems designed to prevent air pollution.
The full range and availability of test materials in AIR PT is determined on an annual basis and further details can be found in the AIR PT application form and scheme description.

AQUACHECK - Water chemistry
Everybody depends on water; it is vital in sustaining all natural systems on and under the earth’s surface. Water sources require regular analyses to determine their safety and suitability for a variety of uses. The water we drink must be good in quality and quantity so that it is free from harmful chemicals and microorganisms in order to guarantee wellbeing. The water discharged by local waste water treatment plants and industry must be monitored to ensure strict compliance with environmental guidelines. Process waters must be kept clean from contaminants to ensure product quality. As water sources can change, regular testing is advised. The types of analysis could vary from simple field testing for a single analyte to complex laboratory based analysis.
The AQUACHECK scheme provides test materials for the analysis of organic, inorganic chemicals and trace elements in clean waters; waste waters and effluents; agricultural soils; sewage sludge; ecotoxicology, radiochemistry and trial test materials. Different test materials are provided for different analytical groups: major inorganic compounds; metals; phenols; organochlorine pesticides and many others. Participants may select any number or combination of groups to suit their analytical requirements. Test parameters within the groups are continually reviewed to ensure they meet current laboratory testing and regulatory requirements.
Test materials are distributed frequently throughout the scheme year. The use of natural matrices ensures that matrix effects are fully represented. Where it is not possible to use natural matrices, the AQUACHECK scheme uses either a synthetic matrix or a simulated material which represents some of the matrix effects likely to occur in real samples. In this way participation in AQUACHECK enables laboratories to monitor and improve the quality of their routine analytical measurements and provides independent evidence of laboratory performance for both laboratory management and customers. It also allows laboratories to demonstrate to regulators and accreditation bodies the validity of their analytical measurements.
The full range and availability of test materials in AQUACHECK is determined on an annual basis and further details can be found in the AQUACHECK application form and scheme description.

CONTEST - Contaminated land
Land contamination can pose both environmental and human health risks. The main causes of contamination are direct discharge of industrial wastes, domestic pollution, over-usage of pesticides, oil and fuel dumping, leaching of wastes from landfills and leaking underground storage tanks which corrode over time releasing toxic substances into previously clean soils.
Participation in a proficiency testing scheme for soil, such as CONTEST, is a requirement of the UK Environment Agency’s Monitoring Certification Scheme (MCERTS) ‘Performance Standard for Laboratories Undertaking Chemical Testing of Soil’.
The scheme includes a comprehensive range of analytes of relevance to the testing of soils. The test materials are available as standard solutions, soil extracts and soil materials for the analysis of metals, inorganic contaminants, organics, soil leachates and solid waste for ‘Waste Acceptance Criteria’ (WAC) in accordance with EN 12457-2:2002, 10:1 single stage leaching test.
The full range and availability of test materials in CONTEST is determined on an annual basis and further details can be found in the CONTEST application form and scheme description.

QWAS - Water microbiology
The Quality in Water Analysis Scheme (QWAS) scheme is solely intended for microbiological analysis of a wide range of water samples, effluents and sludges.
QWAS can help laboratories to meet the requirements of the laboratory standard ISO/IEC 17025, which states that analytical results must be monitored using external quality assessment and the EU Directive 98/83/EC dealing with the quality of water for human consumption.
For laboratories that perform the analysis of water, participation in a relevant proficiency testing scheme can provide confidence that results of these analyses are meaningful and accurate which, in turn, helps to ensure the safety of water.
The full range and availability of test materials in QWAS is determined on an annual basis and further details can be found in the QWAS application form and scheme description.

BAPS - Brewing analytes The BAPS scheme is designed to promote quality in the measurement of a range of chemical, microbiological and sensory analytes in real beer matrices. It is jointly run by LGC Standards and Campden BRI.
Lager and ale test materials are designed to encompass a range of key brewing analytes that are routinely analysed in the brewing industry.
Ale products with high bitterness content and / or high colour value are also available.
Microbiological test materials contain organisms typically encountered in the brewing industry. There is a low level test material for membrane filtration and a high level test material for plate count (spread or pour).
For sensory analysis, participants evaluate various aroma and taste characteristics of real beers and can compare their results with the Campden BRI sensory panel who provide an expert profile with the sample to enable immediate training of panels if required.
The full range and availability of test materials in BAPS is determined on an annual basis and further details can be found in the BAPS application form and scheme description.

DAPS - Alcoholic drinks As well as distilled beverages, DAPS covers analysis of a wide range of alcoholic beverages and intermediate process samples.
There are five different groups available, with a comprehensive range of test parameters.
One of the key tests performed within DAPS is the measurement of alcoholic strength. Duty is normally paid on the basis of the alcohol in the beverage, and so it is a key performance indicator for the product and tax authorities. By monitoring laboratory performance in this key area, laboratories can help ensure that overpayment is not made thus saving money. Underpayment, which could lead to financial penalties, can also be avoided.
Many of the key parameters in DAPS are related to flavour compounds within the beverage and so, by ensuring consistent analysis of these parameters, beverage producers may improve consistency of product across batches.
The full range and availability of test materials in DAPS is determined on an annual basis and further details can be found in the DAPS application form and scheme description.

MAPS - Malt analytes The MAPS scheme covers test materials from the full range of malted barley and barley used for brewing and distilling. These test materials are analysed for a wide range of analytes, using European Brewing Convention (EBC) and Institute of Brewing and Distilling (IBD) methods, as well as a number of other physical and chemical methods. All test materials are sourced from commercially traded malting barleys.
Malt is a complex product and forms a key ingredient in brewing and distilling. It is important in terms of soluble starch content, as this is converted to sugar in the mashing process, partly determining the alcohol yield during fermentation. Malt also makes a contribution to the flavour of the final product, whether it is used to produce a distilled spirit or a beer. Malt is considered the heart of the process, providing most of the sugars and complex carbohydrates which produce the alcohol and flavour. It can also contribute to the physical attributes of beer such as colour and foam.
Meeting the demanding specifications laid down by brewers and distillers is critical to the business of any maltster and is greatly dependent on the quality of the malting barley. For this reason the accuracy of laboratory results is essential as they will ultimately decide if the product is suitable for use in the production plant.
The full range and availability of test materials in MAPS is determined on an annual basis and further details can be found in the MAPS application form and scheme description.

QBS - Soft drinks and fruit juices The Quality in Beverages Scheme (QBS) is specifically tailored for chemists and microbiologists working in the fruit juice, and soft drinks industries (including carbonated drinks). The scheme can also be of value to other laboratories that need to test for general food additives, such as sweeteners and preservatives.
Fruit juice and beverage products are regularly tested to ensure that they are of acceptable chemical and microbiological quality for consumption.
Chemical test materials are ready-to-use liquid matrices, covering product quality and compositional values. This enables laboratories to assess performance and demonstrate compliance with the relevant compositional standards and the statutory limits governing the use of additives. It also shows that the tests used to monitor other ingredients are reliable, which is essential to maintain the organoleptic properties of the beverage so vital to product quality.
Test materials for microbiological analyses cover the main spoilage and indicator organisms and are provided as lyophilised material with a choice of diluent (soft drink or fruit juice) and a test material for analysis using filtration method to meet the laboratory’s particular requirements.
The full range and availability of test materials in QBS is determined on an annual basis and further details can be found in the QBS application form and scheme description.

DAH - Drugs of abuse in hairThe DAH scheme is suitable for all laboratories involved in the analysis of hair for drugs of abuse and provides an independent assessment of measurement quality.
Drugs and their metabolites become incorporated in hair when ingested. Therefore, analysis for these drug residues can provide a useful and accurate assessment of an individual’s intake of drugs over a period of time. The detection time of drugs in hair is significantly greater than other samples i.e. blood, urine and saliva.
Advantages of analysing hair samples for the presence of drugs include a large window of detection, the assessment of the regularity of drug use and sample stability.
Test materials provided consist of real cut (2 - 3 mm pieces) human hair that has been declared free from common drugs of abuse. The analytes are then incorporated by a method that includes soaking. Drug (and / or metabolites)from six major classes are included during the scheme year.
The full range and availability of test materials in DAH is determined on an annual basis and further details can be found in the DAH application form and DAH scheme description.

DAU - Drugs of abuse in urineThe DAU scheme is designed to provide an independent performance assessment of laboratories and clinics that provide routine services for detection of drugs of abuse in urine.
Human urine has been used for many years to detect the presence of frequently abused drugs. A urine drug test may be undertaken when ordered by a doctor to monitor a known or suspected substance abuse patient, and whenever a person has symptoms that suggest drug use. Urine drug tests may be requested for a variety of reasons, including occupational monitoring, insurance screening, legal and forensic purposes and in sports.
Drug testing is extremely accurate and reliable when all aspects of the testing process are carried out correctly. However, if poor procedures and inadequate testing methods are utilised, the information obtained may be very misleading and inaccurate. In order to minimise this risk, clinical laboratories should perform routine quality control tests and participate in suitable PT / EQA schemes.
The full range and availability of test materials in DAU is determined on an annual basis and further details can be found in the DAU application form and scheme description.

DOF - Drugs in oral fluidThe DOF scheme is designed to provide an independent performance assessment of laboratories and clinics that provide analytical services for drugs in oral fluid.
Drug abuse is a global problem affecting many in society. Advances in technology have enabled oral fluid testing for the presence of many drugs.
Oral fluid as a testing matrix is increasingly being utilised in a range of applications, such a work place monitoring, clinical toxicology and criminal justice.
The advantages of oral fluid over traditional fluids such as blood and urine, are that collection is almost non-invasive, is relatively easy to perform, and, in forensic situations, can be achieved under close supervision to prevent adulteration or substitution of the samples.
Due to the importance of results obtained it is essential that laboratories undertaking the analyses are able to demonstrate the testing they perform is dependable, reproducible and accurate. Participation in the DOF scheme will provide valuable feedback to laboratories / on-site screening clinics who undertake these analyses, and a record of results overtime.
The full range and availability of test materials in DOF is determined on an annual basis and further details can be found in the DOF application form and scheme description.

TDM - Therapeutic drugs monitoringThe TDM scheme is designed to provide an independent performance assessment for laboratories and clinics who are involved in the routine quantification of therapeutic drugs in serum.
TDM is the measurement of specific drug levels (concentrations) at timed intervals in patients, usually through blood samples, and is necessary where control of drug concentrations is required to achieve optimum treatment for the patient.
For most drugs, monitoring is not required as they have a wide therapeutic index i.e. the difference between a therapeutic and toxic concentration is large. Therefore, most individuals will be effectively treated without extreme side effects or symptoms of toxicity.
However, drugs with a narrow therapeutic range may result in a high or low serum concentration if not monitored and controlled. Drug concentrations in the bloodstream that are too high have the potential to exert adverse effects associated with toxic or even fatal consequences. Drug concentrations below the therapeutic range can lead to poor response to treatment. For some drugs, maintaining this steady state is not as simple as giving a standard dose of medication.
The full range and availability of test materials in TDM is determined on an annual basis and further details can be found in the TDM application form and scheme description.

TOX - Toxicology The TOX scheme is designed to provide an independent performance assessment for laboratories and clinics that provide a pathology service, toxicological service, or forensic investigation service for drug and ethanol determination.
Drug and alcohol analyses may be undertaken for a variety of reasons which include but are not restricted to:
• Determine whether an individual is under the influence of alcohol and / or drugs that may interfere with any medical care necessary (These analyses are usually required quickly in order to facilitate effective medical treatment)
• Determine whether an individual is under the influence of alcohol and / or drugs which may put their own life or that of others at risk whilst at work
• Determine whether an individual may have been affected by alcohol and / or drugs whilst either a victim or a suspect in a criminal offence
• Determine whether alcohol and / or drugs may be implicated in a death
Toxicological analyses may be undertaken on a number of biological specimens, predominantly blood, serum and urine. In general, analyses are commonly undertaken for a range of prescription and non-prescription drugs, illegal drugs and alcohol. The aim of the analyses is to establish the identity of any substances present and at what quantity, and to then determine what effect the substance(s) identified may have had on the individual. The analytical findings would then be subject to interpretation by a suitably qualified individual.
The full range and availability of test materials in TOX is determined on an annual basis and further details can be found in the TOX application form and scheme description.

COSMETICS - Cosmetics and toiletriesThe use of cosmetics has been commonplace for thousands of years, and the potential for harm to the wearer has been present ever since the use of toxic chemicals such as lead sulfite (galena) as an eye make-up by the ancient Egyptians.
Today it is important that contaminated cosmetics do not enter the supply chain, whether the contamination is due to excessive levels of heavy metals, or microbial contamination which can produce enzymes which can damage the epidermis causing irritation and potentially infection if applied to already broken skin.
The COSMETICS scheme covers chemistry and microbiology test parameters. A lipstick, lip gloss and powdered cosmetic formulation are available for analysis of lead and other metals. In addition to this, a cream test material is available for the analysis of hydroquinone. This analyte is commonly found in products marketed to lighten the skin, and is one of the most toxic ingredients still used in cosmetics. For the analysis of common microbiology contaminants, the range of products includes cream, liquid and powder.
The full range and availability of test materials in COSMETICS is determined on an annual basis and further details can be found in the COSMETICS application form and scheme description.

NiMS - Nickel migrationThe NiMS scheme is designed to assess the performance of laboratories undertaking the determination of nickel release from articles intended to come into direct and prolonged contact with the skin according to the European Regulation (EC) 1907/2006.
The release of nickel from certain products, most commonly earrings and other jewellery for body piercings is the most widespread cause of allergic contact dermatitis - an itchy rash that appears when skin touches a usually harmless substance - affecting people of all ages. Many ordinary items such as buttons, coins, spectacle frames, watch straps, zips etc. may also contain nickel and as such is hard for sufferers to avoid.
The method for the determination of nickel release from such products is defined in European standard EN 1811 (2011). The article to be tested is suspended in an artificial sweat solution for a period of a week, after which time the concentration of dissolved nickel in the solution is determined by ICP-MS or a similarly accurate and precise technique.
The full range and availability of test materials in NiMS is determined on an annual basis and further details can be found in the NiMS application form and scheme description.

PHARMASSURE - PharmaceuticalThe regulations surrounding the manufacture of pharmaceutical products and the laboratories which test them are wide ranging, and compliance with the requirements of GMP/GLP is aimed at ensuring the safety and efficacy of all pharmaceutical preparations. Similarly, the annual revalidation of methods is an important tool in understanding and ensuring that a testing method is working properly. However, these tools are largely internal operations. Regular participation in a proficiency testing scheme, provides an external independent tool for monitoring the effectiveness of methods employed in any laboratory, without the high level of work involved in a full method revalidation.
PHARMASSURE has been specifically designed to meet the needs of the pharmaceutical industry. The reduction of risks associated with the manufacture of pharmaceutical products is the primary objective of the pharmaceutical quality assurance laboratory. There is an abundance of regulations, biological standards, validation procedures and other tools available to the quality control professional to achieve this aim.
In most cases however, the use of these tools is aimed at assessing the product or the environment in which it was produced. The introduction of proficiency testing offers a valuable, independent, tool for the ongoing assessment of the testing procedures, methods employed, laboratory staff responsible for the analysis and subsequent interpretation of results.
The test materials cover chemical, microbiological and physical analysis as well as sterility testing.
The full range and availability of test materials in PHARMASSURE is determined on an annual basis and further details can be found in the PHARMASSURE application form and scheme description.

TOYTEST - Toy safety Play is a vital part of child-development and toys help at every stage from babies to school-age children. Toys are safer than ever before, but we should remain cautious about often hidden hazards of toys. We rely on manufacturers, suppliers and toy legislation to help keep our children safe, and at the same time prevent product recalls and protect brand value.
The TOYTEST scheme allows laboratories involved in the safety testing of toys to monitor their analysis against the current European and American standards.
Test materials are assessed against the requirements of European Standard EN71 and American Society for Testing and Materials (ASTM) F963 toy safety standards. A comprehensive range of test materials and product information will be included over the scheme year to be assessed against the regulations.
Test materials will also be provided for analytical testing, such as paint flakes for cadmium and lead analysis; standard solutions for heavy metal analysis; plastic for analysis of phthalates and other materials for a range of analyses.
The full range and availability of test materials in TOYTEST is determined on an annual basis and further details can be found in the TOYTEST application form and scheme description.

“What could be the cause of my poor performance?”
“A single poor result is not indicative of overall laboratory performance but neither is a single good result. Ideally, PT results should be monitored over time to detect potential bias or repeated unsatisfactory results. There are numerous potential causes of poor performance in a PT scheme which may include analytical and non-analytical errors.”

FAE - Forensic analysis for explosives
The FAE scheme is designed to enable laboratories providing these services to monitor their performance and compare it with that of their peers. The European Network of Forensic Science Institute (ENFSI) Working Group on Explosives provides technical advice to LGC Standards on the organisation of this scheme.
Explosives analysis may be performed in a number of circumstances. Examples of these include the analysis of raw materials found at a scene in what may be a bomb making laboratory (scene), the identification of what may be explosive substances and the forensic identification of post-blast explosive residues.
The full range and availability of test materials in FAE is determined on an annual basis and further details can be found in the FAE application form and scheme description.

FIRMS - Forensic isotope ratio mass spectrometry Isotope Ratio Mass Spectrometry (IRMS) is a specialised technique used to precisely measure small differences in the abundances of isotopes such as 2H/1H, 13C/12C, 15N/14N and 18O/16O. Subtle variations to the ‘natural’ abundance of these isotopes may be introduced during biological, chemical and physical processes
As a result, isotopic variations are found in diverse materials and IRMS therefore has a wide range of applications, in subject areas such as Archaeology, Geosciences, Biological sciences and Forensic sciences.
Over recent years there has been a surge in IRMS application most notably in forensic science where it may be possible to distinguish samples which otherwise share identical chemical compositions.
A laboratory that has little experience with IRMS may obtain results that appear accurate but do not reflect the samples that were analysed.
The Forensic Isotope Ratio Mass Spectrometry (FIRMS) Network was founded to develop the scope of stable isotope techniques in forensic applications. The purpose of the scheme is to raise awareness of the relevance and importance of IRMS in forensic science, crime detection and reduction.
The FIRMS scheme is run by LGC Standards and is supported by the FIRMS Network which provides input for the choice of test materials.
The full range and availability of test materials in FIRMS is determined on an annual basis and further details can be found in the FIRMS application form and scheme description.

QUARTZ - Forensic blood toxicologyQUARTZ is a blood toxicology scheme and is designed for laboratories undertaking analysis of drugs in post-mortem and other blood samples for toxicological purposes, particularly in a forensic context. Case-types that are covered by the scheme include deaths, drug facilitated sexual assaults, impaired driving and other forensic toxicology criminal cases.
Test materials are prepared using pre-screened human blood. Target analytes are added at an appropriate level and the test material mixed to ensure homogeneity prior to despatch.
Drugs and metabolites are included in the scheme that are particularly relevant to forensic toxicology and are discussed regularly with the Advisory Group. The scheme includes various samples containing forensically relevant drugs, in both known quantitative samples and unknown samples involving case scenarios.
Alcohol is a major cause of road casualties and deaths and as penalties for drink-driving are severe, it is essential the accuracy of analysis can be proven in the legal case. Therefore the scheme contains a sample specifically aimed at laboratories who undertake blood alcohol determinations for Driving Offences.
In addition, it may be necessary to undertake a calculation commonly known as an Alcohol Technical Defence (ATD) calculation when there has been a delay between the incident and the evidential sample being obtained and alleged post-incident alcohol consumption during this time period. The scheme includes a case scenario which can be used to demonstrate competence in carrying out the (ATD) calculation.
The full range and availability of test materials in QUARTZ is determined on an annual basis and further details can be found in the QUARTZ application form and scheme description.

OIL PT - Oils and fuelsPetroleum products, such as oils and fuels, are tested throughout their life span, from the time the oil is taken from the ground to beyond the petroleum recyclers. The concentration of contaminants and trace elements is vital in ensuring the quality of oil and petroleum products. Regulations related to cleanliness standards in engines; contamination particles and water in diesel fuel; instability of ultra low sulfur fuels; and many more, mean it is essential that laboratories performing these measurements are capable of producing accurate data.
The OIL PT scheme is designed specifically to assist chemists and engineers working in the refinery, fuel, used oil and lubricant laboratories to meet these regulations. Laboratories performing the analysis of fuels and oils according to ASTM, IP and ISO protocols will be able to monitor their performance and compare it with that of their peers and other laboratories worldwide.
The full range and availability of test materials in OIL PT is determined on an annual basis and further details can be found in the OIL PT application form and scheme description.

QMIS - Microbiology investigation competencyAn area of increasing importance for analysts is being able to demonstrate competency in carrying out fundamental microbiological techniques. QMIS may help with this as it is designed to work alongside all the schemes that require microbiological analysis.
QMIS differs from the normal schemes in that the microbiologist must carry out laboratory techniques and apply further investigative measures in order to identify an unknown single organism. Each test is assessed in the report, as is the overall identification. There is a sample specifically for serology testing, to identify a strain of Salmonella, and a ‘case study’ for enumeration of a typical culture plate. Participants will be given a photograph of a real culture plate with the associated dilution factor. They must calculate the level of the stated organism in the original sample. This is seen as a straight forward procedure, but in our experience interpretation of colonies, enumeration and calculation can lead to significant errors.
The full range and availability of test materials in QMIS is determined on an annual basis and further details can be found in the QMIS application form and scheme description.

Frequently asked questions
70 Tel: +44 (0)161 762 2500 Fax: +44 (0)161 762 2501
Q: Which international standards are relevant to LGC PT schemes? A: All our PT schemes are operated in accordance with the international standard ISO/IEC 17043. The statistical analysis undertaken is in accordance with the international standard ISO 13528. LGC is accredited by the United Kingdom Accreditation Service (UKAS) for the provision of proficiency testing schemes against ISO/IEC 17043; a copy of our current scope of accreditation which lists the accredited schemes is available on our website: www.lgcstandards.com.
Q: How are your schemes organised? A: The day-to-day operation of each scheme is the responsibility of LGC Standards. Individual schemes are managed by a team of Scheme Coordinators, to cover reporting, customer service and technical functions. For some schemes, external advisors may also be used to provide the full range of relevant knowledge and expertise needed to operate the scheme effectively. A small number of schemes are run in collaboration with other organisations.
Q: Do you use Advisors and Advisory Groups? A: Yes, depending upon the scheme in question. Advisors are selected on the basis of their technical knowledge and experience of the industry to which the scheme is related. Advisors may be used on an ad-hoc basis and contacted when specific issues need to be addressed.
Alternatively, formal Advisory Groups may be used. Advisory Groups consist of members who may or may not be participants on the scheme but who are experienced in the field of testing covered by the PT scheme.
The composition and terms of reference of each Advisory Group will be agreed on a scheme-by-scheme basis. Membership of the Advisory Groups is subject to change but members’ names are available on request.
Q: Do you run schemes that are jointly managed? A: Yes, some schemes are operated jointly with a partner organisation. Where schemes are operated jointly, a Management Committee may be set up to address operational issues for the scheme.
Q: How do I join a scheme? A: Participants are advised to take part in the scheme(s) that are most fitting to their own area of testing. Where necessary, appropriate staff at LGC Standards can advise on which scheme is most suitable for participants.
For each scheme, a scheme description and application form will be available, containing information about the test materials included in the scheme, and the intended distribution dates. Participants are invited to complete the application form, indicating which test materials they wish to receive during the scheme year. If the availability of test materials changes during the scheme year, participants are kept fully informed.
Once a completed application form is received, an order confirmation will be sent to the participant, confirming the test materials selected and distribution date.
Q: Can you guarantee my laboratory’s confidentiality? A: In order to ensure confidentiality, participants in all schemes are allocated a unique laboratory reference number. This number enables results to be reported without divulging the identities of participant laboratories. Only staff within the proficiency testing team and the laboratory itself will know this number.
Q: How often do I need to participate? A: The frequency that a laboratory needs to participate in proficiency testing depends on a wide range of factors specific to each individual laboratory, such as other quality tools used, the volume of work undertaken and the risk associated to the measurements. Therefore every individual laboratory may have a different need, which is why schemes provided by LGC Standards offer flexible participation, although some do have a minimum participation level. Third parties, such as regulatory bodies, may recommend minimum levels of participation. To gain the benefit from trend analysis, participation in a minimum of four rounds over a scheme year is normally recommended.
Email: [email protected] Website: www.lgcstandards.com 71
Q: What are the fees for participation? A: Fees for participation are reviewed annually and the current fees for each scheme are available on application. Payment terms are detailed on the application form and invoice. Participants are advised that delays with payments may result in test materials and / or reports being withheld until payments are made.
Q: Where do you source your test materials? A: The vast majority of test materials are manufactured by LGC Standards. Where this is not possible, test materials are carefully sourced to meet the needs of participants. Wherever practical, test materials will be as similar as possible to those routinely tested by participating laboratories. However, in some cases, in order to achieve the required degree of homogeneity and stability, test materials may be in the form of simulated matrices or concentrated spiking solutions.
The analyte concentration range of test materials will usually be varied from round to round in order to be realistic and challenging. Details of individual test material types are available in the relevant scheme description.
Q: How are test materials packaged and transported? A: Test materials are packaged appropriately to protect the contents during transit. The majority of test materials are sent using priority courier. Overseas customers must provide relevant documents to prevent delay in customs such as import permits and may be required to pay import duties locally.
Once packages have been delivered, LGC Standards cannot be held responsible if they subsequently fail to reach the correct personnel or are not stored under the recommended conditions.
Participants are asked to check the contents of packages immediately on receipt and to contact LGC Standards if there are any problems with the condition of the test materials or accompanying documentation.
Q: How is test material stability affected by time, distance and temperature? A: The test materials are all stable at the stated storage temperatures for at least the period of the proficiency test round. Studies have shown there is no significant difference between results of test materials tested the day after despatch and those tested on the deadline date. There is also no evidence that results are influenced by different climatic conditions of participating countries.
Distance travelled does not affect test material results. We have undertaken studies on a number of our PT test materials comparing the average result according to distance travelled, and no correlations have been found. Stability consideration is an important part of the design and feasibility process for a PT scheme, where transport conditions such as temperature, humidity, pressure, exposure to x-rays etc are taken into account.
Q: How do I treat my PT test material? A: It is important for laboratories to understand how to get the optimum benefit from PT participation. To do this, a laboratory must participate in an open and honest fashion, being prepared to, on occasion, be evaluated as unsatisfactory. If PT is to achieve its aims, laboratories need to treat the PT test materials the same as routine test materials, and staff must be encouraged to treat them appropriately and learn from their results in a constructive manner.
Laboratories will learn very little about the quality of their routine work if the PT test materials are given special treatment, such as carrying out a much higher number of analyses, in order to be evaluated as satisfactory. This may in fact compromise the quality of routine measurements as a disproportionate level of effort is being expended for the PT.

Q: Do I have to use specific methods to analyse the test materials? A: Unless otherwise instructed, participants should analyse the test materials using any method that they feel is appropriate. Participants are asked to treat the PT material in the same way as a routine test material.
Participants may be asked to state their method when reporting results. It is important that this information is accurate as results are analysed and reported according to the method stated.
Q: Do I have to report my results within a specific timescale? A: Deadlines are specified for the return of results, to ensure the timely issue of assigned values and reports to participants. For each scheme a closure date will therefore be specified. For certain tests there may also be a date specified by which examination of the test material is recommended to have been commenced. This is to ensure that sufficient time is available to complete the test and report results in time for the deadline date.
Q: How should I report my results using PORTAL? A: For the majority of schemes, results are returned through our bespoke electronic reporting software, PORTAL. Once you are ready to report your results, please go to: www.lgcpt.com/portal You will need to log in using your lab ID, username and password. We advise that prior to using PORTAL you read the user guide which is available at: www.lgcpt.com/portal select ‘help’ from the menu.
If you require further assistance please contact our support team:
Tel: +44 (0)161 762 2500 Email: [email protected] or your local LGC Standards office.
For some schemes (or parts of a scheme) alternative reporting mechanisms are provided, details of which will be emailed to participants prior to test materials receipt.
It is recommended that results and calculations are checked thoroughly before reporting. Results should be reported clearly, in the format and units detailed in the scheme description. If calculations are used, unless
instructed otherwise, the laboratory is to report only the final calculated result.
In general, results of zero should not be reported; results should be reported depending upon the detection limit of the method used, for example, <10. The exception is a small number of parameters, where it may be appropriate to report a result of zero, depending on the measurement scale being used. Results of zero and truncated results, such as < or > cannot often be included in the data analysis and therefore allocated a performance score.
Results will be rounded up or down to the number of reporting decimal places stipulated in the scheme description and may not therefore be identical to your original reported result. The effects of rounding may also mean that occasionally percentage totals do not add up exactly to 100 %.
Part of the challenge of proficiency testing is the ability to perform calculations and transcribe results correctly. The proficiency testing team cannot interpret or calculate results on participants’ behalf. Once submitted and received, results cannot be amended and no changes can be made after the report has been issued. However, if you notice an error in your result before the reporting deadline, this can be corrected using PORTAL until the round closes.
Q: How many results may I submit? A: Although it is desirable for participants to submit multiple results in order to compare results between different analysts, methods or instruments, a single laboratory reporting a large number of results could potentially bias the dataset. In order to minimise the effects of bias, LGC Standards therefore limits the number of results participants are able to report. Each participant is able to enter up to 13 different results. Of these results a maximum of 3 results can be ‘nominated’ results. Nominated results are included in the statistical analysis of the dataset whilst non-nominated results are not, however all results will receive z performance scores and assessments as appropriate. Nominated results must be obtained using different methods, again to minimise the effects of bias.
Email: [email protected] Website: www.lgcstandards.com 73
Further information is available in the PORTAL User Guide and the PORTAL Nominated Results FAQ, both of these documents are available for download from the PORTAL website and further information is available from [email protected].
Q: Can my results be included in the report if I’ve missed the deadline for reporting? A: Participants are asked to return results by the given deadline in order to ensure that their results are included in the statistical analysis and the scheme report. Results received after the closure date will not be included in the report.
For schemes where a generic report is issued, this is available to all participants subscribing to the round regardless of whether their results were submitted or not.
Q: How do you prevent collusion and falsification of results? A: It defeats the objective of taking part in proficiency testing if participants are not returning genuine results. Certain measures are built into the schemes to try and prevent collusion but, ultimately the responsibility rests with each participating laboratory to behave in a professional manner.
Q: How is the assigned value established? A: ISO 13528: ‘Statistical Methods for use in Proficiency Testing by Interlaboratory Comparisons’ sets out how the assigned value and performance assessment criteria can be established and describes the options for the various performance scoring systems.
The assigned value is the value selected as being the best estimate of the ‘true value’ for the parameter under test. The method used to determine the assigned value may vary depending upon the particular scheme and test material and is detailed in the relevant scheme description.
For quantitative tests, where it is appropriate, practicable and technically feasible, the assigned value will be derived through formulation (or occasionally through the use of a certified reference material) to provide metrological traceability; the associated uncertainty of the value can therefore be estimated. However, in many cases the use of a consensus value is the only practicable
and technically feasible approach to use. When the assigned value is determined from the consensus value of participant results, or from expert laboratories, robust statistical methods are used for calculation of the consensus value, the estimated standard uncertainty and the robust standard deviation.
For qualitative tests, participant results are compared against the intended result (assigned value) based on formulation or expert assessment.
For interpretive schemes where the result is subjective rather than quantifiable, a model answer produced by appropriate experts will be published in the report.
For microbiology test materials, all participant results are transformed by converting them to log10 before the statistical analysis is undertaken.
Q: How do I evaluate measurement uncertainty? A: The aim when evaluating measurement uncertainty is to combine the effects of all the errors that will influence the measurement result, into a single value. There are many different guides available which provide advice on evaluating measurement uncertainty. There are two specific guides that are internationally recognised:
• ISO (BIPM, IEC, IFCC, IUPAC, IUPAP and OIML) ‘Guide to the Expression of Uncertainty in Measurement’
• EURACHEM/CITAC Guide ‘Quantifying Uncertainty in Analytical Measurement’ (available at: www.eurachem.org)
Further information on approaches to evaluating measurement uncertainty may also be available from your national accreditation body.
74 Tel: +44 (0)161 762 2500 Fax: +44 (0)161 762 2501
Q: Can I use PT data to estimate my measurement uncertainty? A: It is possible, but must be regarded as a very rough estimate, and is not an approach addressed in many guides to evaluating measurement uncertainty. However documents that do address the use of PT data are:
• EURACHEM/CITAC Guide ‘Quantifying Uncertainty in Analytical Measurement’ (available at www.eurachem.org)
• NORDTEST Report TR 537 ‘Handbook for Calculation of Measurement Uncertainty in Environmental Laboratories’
• ISO/TS 19036 ‘Microbiology of Food and Animal Feeding Stuffs - Guidelines for the Estimation of Measurement Uncertainty for Quantitative Determinations’
Q: What is the Standard Deviation for Proficiency Assessment (SDPA)? A: The SDPA expresses the acceptable difference between the laboratory result and the assigned value. An acceptable z performance score represents a result that does not deviate from the assigned value by more than twice the SDPA. The method used to determine the SDPA may vary depending upon the particular scheme and test material and is detailed in the relevant scheme description.
Q: How do I report a ‘presumptive’ result in microbiology? A: Report your result as usual but record in the comments section that the result is ‘Presumptive’.
Q: What is the purpose of scoring my result? A: Once the assigned value for the parameters under test has been established, participant laboratories are assessed on the difference between their result and the assigned value, with this difference being represented by a performance score called a z score. This provides a simple and consistent measure of performance which is the key to monitoring competence and implementing an improvement programme as required.
Q: How is a z perfomance score calculated? A: The participant’s result, x, is converted into a z performance score using the following formula:
z = (x - X) SDPA
Where: X = the assigned value
SDPA = Standard Deviation for Proficiency Assessment
For small data sets, there will be increased uncertainty around the assigned value if derived from a consensus value from participants’ results. In such cases, z performance scores may not be provided, or may be given for information only.
The z score expresses performance in relation to the assigned value and the standard deviation for proficiency assessment (SDPA). A z performance score of 2 represents a result that is a distance of 2 x SDPA from the assigned value.
A fit for purpose value for SDPA, rather than being derived from participant results, is preferable as this enables z scores to be compared from round to round to demonstrate general trends.
For each scheme, the value of SDPA and the method used to derive it is reported in the scheme description and / or report.
Q: How do I interpret my results? A: For quantitative examinations, participant performance is assessed using the z score, and the following interpretation is given to results:
|z| ≤ 2.00 Satisfactory result
2.00 < |z| < 3.00 Questionable result
|z| ≥ 3.00 Unsatisfactory result
For qualitative examinations or semi-qualitative results, laboratories reporting the assigned result or range of results will be considered correct, and therefore have satisfactory performance.
Email: [email protected] Website: www.lgcstandards.com 75
Q: What are the advantages of a z performance score? A: • Results can be expressed in a form that is easy to interpret and understand • Results can be summarised in graphical or tabular form to depict overall performance • A performance score allows participants to directly compare their own result with others • If consistent statistical values are applied, a performance score enables participants to monitor and trend their own performance over time
It is important to interpret any performance score in the full context of the overall results and in the context of a laboratory’s own quality control measures.
Q: What is the estimated uncertainty of the assigned value? A: The assigned value has a standard uncertainty (ux) that depends upon the method used to derive the assigned value. When the assigned value is determined by the consensus of participants’ results, the estimated standard uncertainty of the assigned value can be calculated by:
ux = 1.25 x Robust standard deviation/√n
Where n = number of results
When the assigned value is determined by formulation, the standard uncertainty is estimated by the combination of uncertainties of all sources of error, such as gravimetric and volumetric measurements.
If ux is ≤ 0.3 x SDPA, then the uncertainty of the assigned value can be considered negligible and need not be considered in the interpretation of results.
If ux is > 0.3 x SDPA, then the uncertainty of the assigned value is not negligible in relation to the SDPA and so z’ performance scores (z-prime), which takes into account the standard uncertainty of the assigned value in their calculation, will be reported in place of z performance scores.
Q: How is z’ performance score (z-prime) calculated? A: A z’ performance score (z-prime) incorporates the standard uncertainty of the assigned value and is calculated as follows:
z’ = (x - X) √ SDPA2 + ux
2
Where: x = participant result
X = the assigned value
SDPA = Standard Deviation for Proficiency Assessment
ux = standard uncertainty of the assigned value X
A z’ performance score is interpreted in exactly the same way as a z performance score, ≤2 is satisfactory, >2 but <3 is questionable and ≥3 is unsatisfactory.
Q: Do you include outlying results due to ‘errors and blunders’ in the statistical analysis of the data? A: Although robust estimators are used in order to minimise the influence of outlying results, extreme results or results that are identifiably invalid should not be included in the statistical analysis of the data. For example, these may be results caused by calculation errors or the use of incorrect units. However, such results can be difficult to identify by the PT organiser.
For this reason, the robust mean and standard deviation will be calculated in the usual way, but those results that are out of the range of the assigned value ± 5 x SDPA will be excluded and the robust mean and standard deviation will then be recalculated. These recalculated values will be used for the statistical analysis. By removing these ‘blunders’ from the dataset any influence on the summary statistics is completely removed.
All results, including excluded results, will be given performance scores.

Q: What could be the cause of my poor performance? A: A single poor result is not indicative of overall laboratory performance but neither is a single good result. Ideally, PT results should be monitored over time to detect potential bias or repeated unsatisfactory results.
There are many possible reasons for a single poor result. It is therefore important to interpret the results from PT schemes within the context of an all-round quality assurance programme, including internal quality control, use of validated methods and reference materials.
There are numerous potential causes of poor performance in a PT scheme which may include analytical and non-analytical errors.
Analytical errors • Calibration / instrument problems • Extraction / clean-up • Interferences / matrix effects • Diagnostic kits / reagents • Analyst / method performance
Non-analytical errors • Calculation / transcription • Reporting format / units • Poor / incorrect storage • Test material defects
Test materials are subjected to rigorous quality control testing before being distributed to participants, and are unlikely to be the cause of a poor z performance score. All possible reasons for a poor performance should be investigated fully in order to identify the most likely cause and to enable action to be taken to prevent recurrence. Repeat test materials are available after every distribution, but it is most important to investigate and understand the reason(s) for the failure, document this fully, and carry out corrective actions before repeating a test.
Q: How can I measure my laboratory’s performance over time? A: You can do this by trend analysis. A single result simply reflects the performance of the laboratory on the particular day that the test was carried out and therefore gives limited information. Frequent participation in PT schemes over time can give greater insight into long-term performance and can help identify where internal bias may be occurring. One of the best methods of summarising performance scores over time is graphically as this gives a clear overview and is less prone to misinterpretation than numerical methods. Participants are therefore advised to monitor their PT results over time. An online trend analysis tool is included in the cost of your PT participation with LGC. The online tool is built into the PORTAL reporting system and allows you to quickly plot your results over a range of rounds and easily download the charts for further circulation. More information regarding interpretation and trend analysis of proficiency results is given in the Eurachem guide on ‘Selection, Use and Interpretation of Proficiency Testing (PT) schemes (available at www.eurachem.org), IUPAC ‘International Harmonised Protocol for the Proficiency Testing of Analytical Chemistry Laboratories’, 2006 and ISO 13528.
Q: How can I graphically plot and analyse trends for qualitative results? A: Qualitative results are difficult to depict graphically as they are not normally allocated a performance score. However for qualitative results, a correct result could be allocated a performance score of 0 to represent a satisfactory result. A false positive result can be represented by a performance score of + 3, whilst a false negative result can be represented by a performance score of - 3. If plotted graphically over time, this should give a clear visual indicator of performance in qualitative tests.
Q: How will I receive my report? A: Following statistical evaluation of the results, the reports will generally be available on the website within 4 to 10 working days of round closure (see specific scheme description). We aim to provide 95 % of our reports to participants within 5 working days. Participants will be emailed when the report is available. The content of reports vary from scheme to scheme
Email: [email protected] Website: www.lgcstandards.com 77
but include details of the composition of test materials, the assigned values, and tabular and / or graphical representations of participants’ results. Paper copies are also available for an additional charge.
Q: How do I assess the reproducibility standard deviation from the PT report? A: The robust standard deviation provided in the PT report for a specific method can be taken as an estimate of the reproducibility standard deviation for the PT round for that specific method.
Q: Can I have a report that only includes my group laboratories? A: Yes, we can produce reports tailored to a customer’s specific requirement. There may be an additional charge for administration and computer programming costs.
Copyright to all reports remains with LGC Standards but permission is granted to participants to make copies for their own internal use, for example for quality control and regulatory purposes. No other copies may be made without obtaining permission.
Q: My results have not been included in the report can I calculate my performance z / z’ performance score? A: To calculate your performance score please visit: www.lgcpt.com/portal.
Select ‘help’ from the menu and download the z / z’ performance score calculator.
Q: How can I receive advice and feedback? A: Communication with participants will be carried out through scheme-related documentation, emails, letters, or through local LGC Standards offices. Open meetings may also be organised and all interested parties invited to attend.
Q: How can I send feedback? A: Comments on any aspect of our products and services are welcome either by phone, fax, letter, email or by contacting your local LGC Standards office.
Q: Can I suggest a scheme or test material? A: We welcome suggestions any time. Please complete the ‘Wish list’ form on our website: www.lgcstandards.com.
Quality control materials
Post-report PT test materials availableAt the end of PT rounds, material is available for up to 3 months to the participants in order to investigate any issues with the analytical process. This is often required by accreditation bodies where there is no obvious non-analytical error (such as a transcription error) that could explain the occurrence of a poor score in a PT round.
Value quality control materialsFor many of our schemes there is ample stock available after the report has been issued, and these are ideal for use as quality control materials within the day-to-day laboratory programme. For many schemes, the samples are commercially produced materials with long shelf-lives, making them the perfect solution for many of your QC requirements.
Proven qualityThe assigned value for the PT test materials is supported by the analysis of many laboratories (in some cases hundreds) and statistical data processing, to ensure the reported values are reliable*.
Benefits of PT test materials for quality control • Proven values, fully documented in the PT report• Excellent value for money• Ideal for method validation• May be used to help establish measurement uncertainty• Perfect for process control between PT rounds• Excellent training tool for new staff• Saves time preparing in-house controls• Helps validate internally prepared materials• Underpins your internal quality procedures
