Which external quality assurance program is required for COVID-19 testing laboratories?

• A. NEQAS
• B. CAP proficiency testing
• C. CLIA proficiency
• D. IQCP

Answer: (A)

External quality assurance involves an independent check on how well a lab performs its tests by using blinded samples and comparing the results to known reference values. For COVID-19 testing, this external benchmark is crucial because accurate and consistent results across many laboratories directly affect patient care and public health decisions. NEQAS, the National External Quality Assessment Service, is a well-established external QA program that provides proficiency testing specifically for SARS-CoV-2 assays and related virology testing. Participation in this kind of external scheme offers objective evidence that a lab can produce correct results, identify areas needing improvement, and maintain reliability over time. This is why it is widely recognized as the required external program for COVID-19 testing laboratories. CAP proficiency testing and CLIA proficiency relate to proficiency testing in general, with CAP being one provider of external PT and CLIA describing requirements in the U.S. context, while IQCP refers to an internal quality control plan. These are not the named external QA program specific to the standard requirement for validating COVID-19 test performance in the same way NEQAS is.
