✍️ Sample CLIA Questions & Answers
1. During a method validation for a moderately complex test, a laboratory calculates a total allowable error (TEa) of 10%. The observed total error is 12%. What action is required?
When observed total error exceeds TEa, the method fails validation and must not be used for patient testing until the source of error is identified and corrected.
2. Why is documentation important in regulatory compliance?
Documentation is vital for regulatory compliance as it provides objective evidence that a laboratory is adhering to all applicable standards and regulations. Well-maintained records demonstrate due diligence, support internal quality assurance, and are essential for successful regulatory inspections and audits. This proof ensures accountability and transparency in laboratory operations.
3. Which type of QC procedure evaluates performance between different analysts, instruments, or time periods within the same laboratory?
Between-run (intermediate) precision captures variability across different runs, days, analysts, or instruments within one laboratory.
4. What is a biohazard?
A biohazard refers to biological substances that pose a threat to the health of living organisms, primarily humans. In a clinical lab, this includes infectious agents, human blood, body fluids, and other potentially infectious materials that can transmit disease. Identifying materials as biohazards is essential for implementing appropriate handling, containment, and disposal procedures to prevent exposure and infection.
5. Which CLIA-deemed accreditation organization is specifically known for laboratory accreditation in pathology and clinical laboratory science?
The College of American Pathologists (CAP) is a CMS-deemed authority widely recognized for laboratory accreditation.
6. Which CLIA-mandated document describes the step-by-step procedures a laboratory uses to perform each test, including specimen requirements and reference ranges?
CLIA requires a comprehensive procedure manual with detailed instructions for each test, including specimen collection, reagents, calibration, QC, and reference ranges.
