proficiency testing
External quality assessment using standardized samples to evaluate laboratory testing accuracy and precision.
Full Definition
Proficiency testing involves laboratories analyzing standardized samples with known values to assess their analytical performance and ensure accurate results. In newborn screening, laboratories must participate in proficiency testing programs for each analyte they test. Results are compared against target values and peer laboratories to identify potential analytical problems. Poor proficiency testing performance triggers investigation and corrective action requirements under regulatory oversight.
Usage
Usage note: Hyphenate when used as an adjective: 'proficiency-testing program'.
