PT Providers

Proficiency Test Providers

L-A-B, in seeking to maintain our ILAC and APLAC signatory status, requires that accredited laboratories participate in Proficiency Testing activities supporting their scopes of accreditation.

The use of Proficiency Testing providers, and specifically ISO/IEC 17043 Accredited PT providers, which operate a quality system in accordance with ISO/IEC 17043 are the preferred methods for assuring quality and proficiency testing per L-A-B Policy 002. L-A-B has collected a listing of PT providers that have been known to operate PT programs in accordance with ISO/IEC 17043.

It is each laboratory’s responsibility to determine if a particular PT program they are interested in is operated in accordance with ISO/IEC 17043 (formerly Guide 43) and to assure the PT program is appropriate for the measurements or test technologies on its scope of accreditation.
