What is a major requirement for labs performing moderate- to high-complexity tests?

• A. Proficiency testing
• B. Staff training
• C. Patient consent
• D. Insurance verification

Answer: (A)

External quality assessment through proficiency testing is required for labs that perform moderate- to high-complexity tests. Proficiency testing involves sending blinded samples to multiple labs, which analyze them and report results. The performance is then compared across labs and to reference values; consistent acceptable performance demonstrates the lab’s ability to produce accurate results. If results fall outside acceptable ranges, the lab must investigate, implement corrective actions, and continue PT as mandated. This external check helps ensure accuracy and reliability of complex testing across different laboratories. Staff training is essential for maintaining competency, but proficiency testing is the formal, regulatory mechanism that directly safeguards test accuracy across labs. Patient consent and insurance verification relate to patient rights and billing, not the regulatory requirement for test performance quality.
