Proficiency Testing, commonly referred to as "PT," was originally developed as an educational tool to help laboratories investigate internal procedural problems and take corrective action to minimize the effect on patient results. PT is the practice of testing specimens of unknown values sent from an outside source three times a year.
After submitting test results, the laboratories receive data that compares their performance with that of other labs that did the same procedures on the same specimens. To ensure the quality of these tests, the law requires that most facilities participate in proficiency testing PT procedures as an external quality control. Physicians who perform any testing procedures in their offices, therefore, are subject to these CLIA regulations.
