Objectives
At the end of this module, you will be able to: Describe the importance of specimen
management. Define the specimen management process
for receipt, rejection, identification, transport, storage, inventory and disposal.
Identify policies and procedures needed to support specimen management.

importance of specimen managementWhy is specimen management important?

Specimen Management Means…
Policies, procedures and infrastructure to
support the safe handling and treatment of
biological specimens

Specimen Management Leads to High Quality Testing
Lab test results are only as good as the condition of the specimen allows– Garbage in, garbage out!
Ensures the result is connected to the right specimen and patient
Ensure quality specimen management for accurate test results
Lab safety

components of specimen managementWhat is involved in specimen management?In what parts of the process is it especially important to control quality?
![Page 9: HIV Drug Resistance Training](https://reader036.fdocuments.net/reader036/viewer/2022062723/56813ffe550346895dab2d13/html5/thumbnails/9.jpg)

What can happen to a specimen?
Map it out! Trace the path of a single specimen (plasma or DBS) from the time it enters your lab to the time you dispose of it.
What happens to the specimen during that time? What could happen to the specimen to compromise lab safety or testing quality?

11
Receiving Specimens
Inspect specimens upon receipt:– Treat shipping package and specimens as
potentially infectious material. Open containers within a Biological Safety Cabinet.
– Examine incoming specimens and paperwork. Document date and time received and receiver’s initials on Requisition Form.
– Complete and submit Data Clarification Form if there are any discrepancies or problems with shipment.
– Complete the Specimen Tracking Log by using the data from the electronic requisition form.
![Page 12: HIV Drug Resistance Training](https://reader036.fdocuments.net/reader036/viewer/2022062723/56813ffe550346895dab2d13/html5/thumbnails/12.jpg)
12
Specimen Quality Evaluation
Inspect specimen quality based on genotyping requirements– Plasma specimen—frozen and shipped with dry
ice– Dried blood spots—shipped either at ambient
temperature or frozen, based on the lab SOP Check label
– Compare specimen label to shipment paperwork– If discrepancies are noted, resolve the issue
before testing.

13
Rejecting Samples
Reject specimens with incomplete identification on the requisition and/or specimen. Do not test these samples unless the information is clarified.
Reject specimens with evidence of contamination, leakage or spillage in transit. Report back to the client with the appropriate rejection message.
Reject if insufficient volume for testing. Reject specimens whose integrity/stability
is questionable due to improper storage conditions during transportation.
![Page 14: HIV Drug Resistance Training](https://reader036.fdocuments.net/reader036/viewer/2022062723/56813ffe550346895dab2d13/html5/thumbnails/14.jpg)
14
Labeling specimens
Once all the samples have been inspected and met acceptance criteria, – Assign a unique lab specimen ID to each
specimen– Place the label on each specimen
![Page 15: HIV Drug Resistance Training](https://reader036.fdocuments.net/reader036/viewer/2022062723/56813ffe550346895dab2d13/html5/thumbnails/15.jpg)
15
Pre-testing Storage andGenerating Pending List
Generate a pending list for specimens received.
Assign testing responsibility. Communicate with requesting clients and
determine turn around time (usually 2 wk-6 months depend on the quantity of the shipment).
![Page 16: HIV Drug Resistance Training](https://reader036.fdocuments.net/reader036/viewer/2022062723/56813ffe550346895dab2d13/html5/thumbnails/16.jpg)
16
Specimen Inventory and Post-Testing Storage
Store specimens in the appropriate freezers for at least 6 months post testing. (Special purpose specimens can be stored for up to 5 years.)
Record the storage location on the Freezer Inventory Form and document it.– How to label specimen
storage location:• Freezer name/number• Shelf number• Box number/location
– Example: H-2-5A5
![Page 17: HIV Drug Resistance Training](https://reader036.fdocuments.net/reader036/viewer/2022062723/56813ffe550346895dab2d13/html5/thumbnails/17.jpg)
17
Disposing of the Specimens
Establish policies on when and how to dispose stored specimens.
Usually maintain specimens in the laboratory a minimum of six months to allow for repeat testing or verification of data purposes.
If any specimens are discarded, update the information in the electronic/hard copy Specimen Tracking Log.
Discard Date Discard By

Policies and Procedures
What policies do we need to develop or enhance to ensure the quality control and safety of specimens used for genotyping?
![Page 19: HIV Drug Resistance Training](https://reader036.fdocuments.net/reader036/viewer/2022062723/56813ffe550346895dab2d13/html5/thumbnails/19.jpg)
19
Policies: Turnaround Time
Lab should have clear policy on turnaround time.
Turnaround time is one of the key factors that evaluate lab service quality to its clients.
Specify priority for genotyping specimen testing.
Usually patient specimens should be tested as soon as possible and return results with the minimal turnaround time.

Discussion
Think of your current lab policies related to specimen management.
What changes, if any, should be made to policies to ensure the quality of genotyping results?– Transcription errors
• Mislabeling DBS card• From lab register to specimen transfer log• From reference lab to testing site
– Inadequate specimens

Procedures and Forms
SOP for specimen management Related document and forms:
• Results Reporting Procedure • Shipping and Export Procedure • Occurrence Management Form• Customer Communication Form• Specimen Tracking Log• Drug Resistance Requisition Form• Data Clarification Form• Freezer Inventory Form
Examples of these forms in handout

Reflection
What does specimen management mean? What are the different components of
specimen management in the life cycle of the sample?
What work does your lab need to do in this area?
![Page 23: HIV Drug Resistance Training](https://reader036.fdocuments.net/reader036/viewer/2022062723/56813ffe550346895dab2d13/html5/thumbnails/23.jpg)
23
Key Messages
Specimen management ensures accurate genotyping results.
If needed, the original specimen can be easily traced and pulled out for retesting or verification purpose.
