Proficiency Testing General Information




Endorsed by ISBER, IBBL’s Biospecimen Proficiency Testing programme is an external quality assessment tool to verify the precision and accuracy of your biospecimen testing methods, and the efficiency of your processing methods.

Key dates to keep in mind:

  • May 20 - Registration opens online (
  • August 23 - Registration closes
  • September - Standardized samples will be shipped to your location
  • November - Data submission deadline
  • February - Your report(s) will be sent electronically

Why participate?

  • Compare your performance to others
    The principle of performance benchmarking applied in our PT programme 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 organisations that are seeking compliance with 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 programme will also prove consistency of performance over time.
  • Gain credibility & visibility
    By participating in our PT programme 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.

How does it work?

In the end, each participant receives:

  • a performance report
  • a certificate of participation
  • a label of participation
