Accredited Proficiency Testing Providers

Accreditation bodies use Proficiency Testing- PT (external quality assurance) programs as part of their procedures to evaluate the capabilities of the laboratories to perform tests at a highly professional level (particularly for the tests which have been accredited).

Standards ISO 15189 and ISO/IEC 17025 requirements for participation in an appropriate proficiency test, when this is available.

Preferable suppliers for PT schemes are those accredited according to ISO /IEC 17043. If there are no suppliers accredited to ISO/ IEC 17043, it is preferable to use those declaring that they implement the rules of ISO/IEC 17043.
For your convenience, please find a reference to the list of suppliers:

  • See link to EPTIS, including a database of hundreds of PT schemes operated in Africa, Europe, USA & Australia.
  • In addition please find the following partial lists of suppliers. Those lists provide no recognition for the PT suppliers.

For your information, this list is incomplete as several other suppliers for proficiency testing scheme are available.

If you are unable to find a relevant program from the list, contact us and we will do our best to assist you.

Inter-laboratory Comparisons

Inter-laboratory comparison is an alternative means of checking for a laboratory’s competence where specific PT schemes don’t exist.
