Laboratory Quality Assurance

Proficiency Testing Monitoring 

The Office of Laboratory Quality Assurance (LQA) monitors proficiency testing (PT) performance according to the Clinical Laboratory Improvement Amendments (CLIA) requirements for PT.

Laboratories must authorize their proficiency testing company to release their PT results to Laboratory Quality Assurance for monitoring. This is done at the time of enrollment in the PT program for the current year. If the PT company does not send copies of PT results to LQA for monitoring, the laboratory will receive an unsatisfactory grade for non-participation and may jeopardize the facility’s Medical Test Site license. LQA will notify the federal Health and Human Services Centers for Medicare & Medicaid Services (CMS) of any adverse actions relating to PT; this information will be published by CMS in its annual Laboratory Registry Report.
