Proficiency Testing General Information

Why participate?

  • Compare your performance to others
    The principle of performance benchmarking applied in our PT program means that your results will be compared to those of other laboratories, from different sectors all over the world.

  • Comply with certification & accreditation requirements
    Proficiency testing offers organizations that are seeking compliance with ISO 20387, ISO 17025, ISO 15189, CLIA, CAP or equivalent, the opportunity to fulfil the respective normative requirements.

  • Improve performance & prove consistency
    The assessment of your laboratory’s proficiency allows you to monitor and improve performance by identifying potential problems and providing additional motivation. Regular participation in our PT program will also prove consistency of performance over time.

  • Gain credibility & visibility
    By participating in our PT program you can assure customers, collaborators, funding agencies and regulatory bodies of the validity of your results. This can help build your reputation for high quality laboratory methods and gain international visibility.
