Reviewer: Rory Huschka, M.Ed., MT(ASCP)

This course addresses proficiency testing (PT) in the clinical laboratory. It outlines the guidelines for performance, documentation, result reporting, and corrective action of PT samples. The course describes circumstances that constitute PT referral and inappropriate communication related to PT events, the use of alternate PT procedures in laboratory practice, compliant modification in standard PT protocols for multiple testing methods for a single analyte and molecular test methods among other topics.
