What is Proficiency Testing (PT)??
Proficiency testing is a very important QC tool for every testing laboratory and helps in determining the performance of individual laboratories for specific tests or measurements. It also gives confidence in the laboratory equipment, methods and staff, and also assures that lab is delivering the quality results demanded by customer.
In a proficiency test one or more well homogenized samples are sent to number of participating laboratories. Each laboratory measures the measurand and reports its results to the Proficiency Testing Provider. The results are compared with the reference value for that measurand by using various statistical tools and the participants are informed.
