What is a PT scheme?

Proficiency testing involves the use of interlaboratory comparisons for the determination of laboratory performance. The need for ongoing confidence in laboratory performance is not only essential for laboratories and their customers but also for other interested parties, such as regulators, laboratory accreditation bodies and other organizations that specify requirements for laboratories.

ISO/IEC 17011 requires accreditation bodies to take account of laboratories' participation and performance in proficiency testing.
