Proficiency Testing General Information

Biorepository Proficiency Testing Program

Endorsed by ISBER, IBBL’s Biospecimen Proficiency Testing program is an external quality assessment tool to verify the precision and accuracy of your biospecimen testing methods, and the efficiency of your processing methods. At the end of the program, each participant will receive a performance report, a certificate of participation, and a label of participation.

Registrations of the 2025 PT programme are now open until August 31, 2025! ISBER members receive a 15% discount. Learn more below or sign up now.

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.

*For Testing Schemes (except the THIS25 scheme), you may test multiple methods in the same run according to the lists of accepted methods. You will however only be able to submit one result per method. For all testing schemes, you may enter replicate measurements in order to assess the within-laboratory variability.

For shipments of PT schemes form/to IBBL:

For participants outside EU and US/Canada: the shipment effective cost of PT schemes from
IBBL to participants will be covered by the participants.
For the shipment of PT derivatives to IBBL, the cost will be covered by the participants.

The street address on the registration form will be used as the SHIPPING address. If the samples should be shipped to a different address, please send that address to ISBERPT@lih.lu.For more information visit us on Biospecimen Proficiency Testing Luxembourg Institute of Health lih.lu or contact us at ISBERPT@lih.lu.
