Why is Proficiency Testing Important?
The detailed data helps laboratories identify problem areas, take corrective action and then verify results as part of their ongoing participation in proficiency testing and commitment to quality service. It has also been demonstrated that ongoing participation in PT tends to improve laboratory quality and performance. PT participation is also a mandatory requirement of laboratory accreditation to ISO/IEC 17025, the international standard governing the operation of testing and calibration laboratories.
