Sample 3 To prepare BS-3, urine was spiked with Sodium gammahydroxybutyrate (14427ng GHB/ml, ). The spiked urine was dispensed in 50ml aliquots and lyophilised

Sample 4 BS-4 was a blank test sample prepared from urine containing no substance in the ICE menu. The sample contained urine spiked with Ephedrine hydrochloride (2700ng/ml, 2308ng base/ml). The spiked urine was dispensed in 50ml aliquots and lyophilised.

Introduction

An important element of the UNODC International Quality Assurance Programme (IQAP) is the implementation of the International Collaborative Exercises (ICE). The exercises allow laboratories, from both developing and developed countries, to continuously monitor their performance in drug testing on a truly global scale. Two rounds are offered per year with each round presenting participants with four different test samples for analysis.

This report provides information on the analytical results of laboratories participating in the Biological Specimens (BS) group. In order to maintain confidentiality, the participating laboratories have been assigned random “Web Codes”, which change every round. The analytical results returned by laboratories participating in ICE are evaluated by UNODC and a confidential report is provided to each laboratory on its own performance. The overall analytical results are reviewed by the UNODC’s International Panel of Forensic Experts which oversees the implementation of these exercises, and offers guidance and support in addressing relevant quality issues. The exercises provide an overview of the performance and capacity of participating laboratories and enable UNODC to tailor technical support in the laboratory sector for greatest impact.

Comments from the International Panel of Forensic Experts

Participation of laboratories

Samples within both the Seized materials (SM) and Biological Specimens (BS) test group were sent to 167 laboratories in 57 countries. 68 laboratories participated in the BS test group and 58 (85%) laboratories submitted the results of their analysis in time for inclusion in the summary report, with 96% using the ICE portal for return of results. The almost universal usage of the ICE portal continues to be a high endorsement of its utility.

Qualitative and Quantitative Analysis of the biological specimens test samples

Overall, the level of performance in identification of the test samples was good given the inherently higher level of difficulty in the analysis of biological specimens compared to seized materials. The complexity of the test samples in ICE 2013/1 was increased in order to challenge the participants. BS-1 contained morphine, 6-monoacetylmorphine and codeine, which were identified by 79%, 79% and 91% of participants respectively. It is encouraging to note that 71% of participants identified all three components in BS-1 and only five false positive results were reported. BS-2 contained amphetamine and a mixture of three benzodiazepines (nordazepam, oxazepam and temazepam). While only 42% of participants identified all four components, 86% identified at least one of the benzodiazepines and 65% identified the amphetamine present. There were eight false positive results including four for diazepam. While the benzodiazepines present are metabolites of diazepam, their presence alone does not represent use of diazepam. BS-3 contained gammahydroxybutyric acid (GHB), a new substance on the ICE menu for the BS test group and 22% of participants identified its presence, while 64% of participants did not carry out analysis for identification of GHB. It is recognized that while GHB may not be commonly analysed by all participants, it has been included in the ICE menu as it represents an example of a more recently abused substance and at the Commission on Narcotic Drugs in March 2013, GHB was transferred from schedule IV to schedule II of the Convention of Psychotropic Substances of 1971. BS-4 was a blank test sample containing no substances from the ICE menu. Although it did contain ephedrine, a precursor to methamphetamine. 19% of participants identified the ephedrine and among five false positives, there was one for methamphetamine.

The results for quantitative analysis within the BS test group were excellent. For BS-1 24 out of 25 (96%) laboratories quantified the morphine, 21 out of 22 (95%) quantified 6-MAM and 22 out of 23 (96%) quantified codeine with acceptable Z-scores. Within BS-2, the quantitation results were equally as good with 20 of 21 (95%) laboratories quantifying the amfetamine, 20 out of 22 (91%) the nordazepam, 13 of 16 (81%) the oxazepam and 14 out of 16 (88%) the temazepam with acceptable Z-scores. Within BS-3, 7 out of 9 (87%) participants quantified the GHB present with acceptable Z-scores. It is encouraging to note that of those laboratories who did carry out quantification, 52% performed quantification on at least seven of the eight substances in all test samples. The predominant analytical techniques used by participants for quantification within the BS test group were GC/MS (79%), followed by LC/MS (38%) and others at (17%).

Laboratories are encouraged to carry out quantification as it can improve the quality of laboratory analyses and can be helpful in assessing the significance of the results. Also, laboratories reporting false positive or false negative results should investigate the reasons for this and corrective actions should be taken in order to continuously improve performance. Participation in ICE also helps in monitoring the effect of corrective actions.
