Skill Check
You are about to perform an Human Immunodeficiency Virus
(HIV) enzyme-linked immunosorbent assay (EIA) run on 24
specimens. Upon recording the PIDs on the plate template, you
notice two specimens that have the same PID. How would you
proceed?
A. Consult with the supervisor; discard the two specimens;
notify study clinic
B. Abandon the whole run and seek clarification before proceeding
C. Consult with the supervisor; proceed with testing; if both
negative or positive, report results
D. All of the above
E. None of the above

Skill Check
A Section Supervisor notes that the potassium value generated
by the analyzer is 9.2 mmol/l (reference range 3.1 – 5.0).
Select the most appropriate steps that should be taken.
A. Release the results
B. Verify that quality control (QC) and calibration are
acceptable before releasing the results
C. Verify QC and calibration; notify the clinic and document
notification before releasing the results
D. Check the specimen for hemolysis; verify QC and
calibration; notify the clinic; and document notification
before releasing the results

attention to avert significant study
participant/patient morbidity or mortality
Values should be defined by the Laboratory
Director, in consultation with clinicians served
Policy/procedure for immediate contact of key
study personnel
36
Critical Values (cont'd)
Date and time of notification
Notification
records should
include:
ID of personnel making the
contact
Person notified and
message relayed
Problems encountered with
accomplishing the task
37
Critical Values (cont'd)
An emergency telephone
contact list for the key study

entire order to verify accuracy of
transcription
38
Skill Check
The only sample for the day from the study clinic (30-minute
drive away) is received at the Central Laboratory for CBC
testing on a Friday afternoon. A PID number mismatch is
noted between the request form and the specimen label
although it appears that one digit seems to have been
omitted on the specimen label. The clinic closes early on
Fridays. Per the Laboratory Standard Operating Procedure
(SOP), specimens with PID mismatches should be rejected.
39
Skill Check
What should the laboratory personnel do?
A. Assume that this was a transcription error and process
the sample
B. Reject the sample as per SOP instruction
C. Process the sample and withhold release of results
until the issue is resolved
D. Place the specimen in the refrigerator for resolution of
the query the following week

Repositories
Sample
repositories
should be
created by
suitably
storing the
samples
44
Relevant
records for
repositories
should be
traceable and

be properly
labeled before
storage
Specimen Shipping
Proper organization, packaging,
shipping, and handling of
specimens ensure specimen
integrity, while maintaining
timely and safe transfer of

All federal and in country
Transportation of Dangerous
Goods Regulations must be met
for the transportation of specimens
45

Matches the number of specimens in the box

Matches the ID numbers on specimen tubes

Contains the necessary data for each PID

Certification
Personnel who
ship specimens
must have
