Proficiency Testing Service

In 2006 PNAC conducted the very first PT program in Pakistan with the collaboration of QRI. In this PT program, QRI contributed with sampling, bottling, labeling, homogeneity and stability studies. This exercise proved to be successful. In the subsequent years, QRI conducted its own PT program based upon the successful venture with PNAC. Organizing PT programs in Pakistan by QRI was need of the time as there was no such program available in Pakistan and the laboratories in Pakistan seeking accreditation from PNAC were obliged to participate in appropriate PT programs operated by foreign based organizations.

Why it is necessary to participate in Proficiency Testing ?

Participation in appropriate PT scheme is not only one of the essential tools for the external evaluation of the performance and reliability of the testing results but it is also fulfills one of the requirements of the accreditation standard ISO/IEC 17025, in order to demonstrate impartial comparability of results. Participation in PT provides the laboratories an excellent opportunity to demonstrate their performance.

Benefits of PT participation:

  • While some laboratories may view participation in PT program as a necessity only to satisfy the requirements of accreditation bodies, they could be overlooking the more fundamental benefits that can be achieved by taking part in well-designed PT program.
  • Clearly the laboratories are the major stakeholders in PT program participation, but there may be other stakeholders who also have a major interest in such programs and in the performance of laboratories involved i.e. professional bodies, regulatory authorities, reference materials producers, direct & indirect customers etc.
  • The following are some of the potential benefits for PT participating laboratories:
  • Compliance to the accreditation requirement.
  • Determining method precision and accuracy.
  • Demonstrate competence.
  • Comparing methods and procedures.
  • Improve testing performance.
  • Training & educating of staff.
  • Instilling confidence in staff, management & lab customers / clients.
  • Comparing analysts’ capabilities.
  • The remaining amount of PT sample is considered as best reference material provided it is maintained under stable conditions.
  • Finally, the successful performance of a laboratory in a proficiency test (or its effective correction of testing problems after an unsuccessful performance) may provide accreditation bodies with confidence in the laboratories for granting and/or maintaining accreditation. The clear benefit for the laboratories is the confidence of their standing as competent organizations. Repeated PT participation will provide them excellent opportunity to ensure that results of laboratory are consistent over time.
