Classification of Tests
Stem
A hospital laboratory receives a request to add a rapid antigen
test for influenza performed on a point-of-care analyzer in the
ED. The lab director must decide test complexity, oversight, and
personnel qualifications. Which laboratory action best aligns
with the federal regulation governing test complexity and
personnel requirements?
,A. Classify the test as waived so any ED staff can perform it
without laboratory oversight.
B. Classify it as moderate complexity and ensure testing
personnel have documented training and competency
assessment.
C. Defer classification to the device manufacturer’s marketing
materials without further verification.
D. Allow testing to proceed under physician supervision without
formal competency documentation.
Correct Answer
B
Rationale — Correct (B)
Moderate complexity tests require documented training and
competency assessment for personnel, and laboratory oversight
in accordance with the federal regulation. This ensures
proficiency and quality monitoring for point-of-care devices that
are not waived. Selecting B addresses both regulatory and
quality responsibilities.
Rationale — Incorrect
A. Not all rapid antigen tests are waived; misclassification risks
noncompliance and QC lapses.
C. Manufacturer materials inform but do not replace regulatory
classification and laboratory verification.
D. Physician supervision alone does not satisfy required
documented competency and quality systems.
,Teaching Point
Verify test complexity; moderate/waived classification dictates
training, QC, and personnel documentation.

Accreditation & Proficiency Testing
Stem
During a mock inspection, the laboratory’s proficiency testing
(PT) records show three PT samples with correct results but
missing signatures on the result log. The lab is accredited by the
major pathology accreditor. What is the best corrective action
to both satisfy accreditation expectations and maintain PT
integrity?
A. Repeat the PT samples outside the official PT program and
document signatures.
B. Add retroactive signatures to the logs and note that the
samples matched expected results.
C. Notify the accreditor and PT provider of the documentation
lapse, document corrective actions, and retrain staff.
D. Ignore the missing signatures since results were correct and
no patient harm occurred.
, Correct Answer
C
Rationale — Correct (C)
Accreditors and PT providers require documented chain-of-
custody and authorized signatures; notifying the accreditor/PT
provider, documenting corrective action, and staff retraining
preserve program integrity and regulatory compliance.
Transparency is essential for PT credibility.
Rationale — Incorrect
A. Repeating outside official PT invalidates the PT process and
does not retroactively correct noncompliance.
B. Retroactive signatures are falsification and violate
accreditation and legal standards.
D. Documentation lapses are regulatory issues even if results
matched; ignoring them risks sanctions.
Teaching Point
PT requires documented chain-of-custody and authorized
signatures; correct lapses transparently.
