External Quality Assessment (EQA) or Proficiency Testing in Molecular Diagnostics There are four methods for EQA/PT: rechecking or retesting samples that have previously been tested by an reference laboratory, on site evaluation, inter-laboratory exchange of samples (usually between a few laboratories), and proficiency testing.
It primarily measures accuracy because each laboratory's results are compared to the interlaboratory mean, which is assumed to be the true value. It is a key indicator of laboratory quality monitored on an ongoing basis. The Clinical Laboratory Improvement Amendments of 1988 (CLIA 88) applies to all facilities that perform tests on human specimens. In today's global marketplace, companies must look beyond themselves to attain the pinnacle of quality. ISO/IEC 17043:2010 Conformity Assessment—General Requirements for Proficiency Testing. It is the laboratory's responsibility to effectively troubleshoot and resolve all proficiency testing failures. PT is educational and promotes continuous learning; it supports laboratories in implementing new biomarkers into clinical testing as well as maintaining . The download section below contains a list of the Clinical Laboratory Improvement Amendments (CLIA) approved proficiency testing (PT) programs for 2021 and a list of the non-waived testing for which PT is required.
External Quality Assurance also known as proficiency testing is an interlaboratory peer program that compares a laboratory's test results using unknown specimens to results from other laboratories using same or similar methods.
