POCT oversight requires that analytical systems demonstrate acceptable performance before patient testing. Out-of-range QC indicates potential problems with reagents, strip lot, environmental conditions, operator technique, or device malfunction. The correct response is to take the meter out of service immediately, perform troubleshooting per procedure (verify strip lot and expiration, control vial integrity, environmental temperature/humidity, operator steps), and repeat QC. Patient testing must not proceed or be reported until QC is within manufacturer and laboratory-defined limits. Option A violates quality policy by continuing clinical testing with an unverified system. Option C has no scientific basis; averaging does not restore accuracy. Option D assumes the issue is coding; modern meters often auto-code, and changing codes without root-cause assessment can mask underlying failures. Documentation of the event, corrective actions, and successful repeat QC is essential for compliance, traceability, and patient safety. These steps reflect competency expectations for phlebotomists with POCT responsibilities under waived and moderate-complexity testing frameworks.
