The Reference Institute for Bioanalytics (RfB), part of the non-profit Foundation for Pathobiochemistry, has published the program booklet for the 2026 proficiency tests (https://rfb.bio/download/ringversuch-programm-2026/). All information on dates, prices and offers is now available on the redesigned website www.rfb.bio . The revised structure facilitates access to all relevant content and supports laboratories and specialist staff in planning their participation.

Why the proficiency tests are important

For decades, the RfB’s proficiency tests have made a significant contribution to external quality assurance in medical laboratories. The DAkkS accreditation according to DIN EN ISO/IEC 17043 confirms the high reliability of the programs. In this way, the proficiency tests create trust among laboratories, doctors and patients and ensure permanently high quality standards in laboratory medicine.

What’s new in 2026

1. More practical structures: The interlaboratory tests were reorganized in order to better map processes in everyday laboratory work and to use resources more efficiently.
2. Expanded educational offerings: New training formats and debriefings enable participants to analyze and improve their results in a targeted manner.
3. International cooperation: Closer cooperation with international partners will make quality standards more comparable worldwide.
4. Digital solutions: Improved online features and new digital tools simplify participation and accelerate the delivery of results.
