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:
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.
