What is Proficiency Testing?
DRIVING QUALITY TOGETHER
WHAT IS PROFICIENCY TESTING? Proficiency testing (PT) is a mechanism for objectively evaluating a laboratory’s performance by the use of independent external means, and includes regular comparisons of a laboratory’s measurement or test results with those of other laboratories. PT is widely recognised as an essential tool for demonstrating the competence of laboratories, providing the infrastructure for a laboratory to monitor and improve the quality of its routine analytical measurements. PT can provide both evidence of competence and an indication of an underlying or emerging problem.
