The EURL Berlin is planning to organise two proficiency tests in 2023. Scheduled for the first and second quarter is a proficiency test on coccidiostats in liver. The participants will be provided with 3-4 test items produced from incurred samples.

Due to the positive feedback to the first proficiency test using standard solutions conducted in 2021 (STRD0521), the EURL Berlin has decided to conduct a PT of the same type in late 2023. Participating laboratories will be provided with 3-4 mix solutions of analytes belonging to several substance groups and are asked to determine the analyte contents. This PT shall give the participants the opportunity to check their own standard solutions against a gravimetrically prepared solution.

Laboratories eligible for participation in any of the projected PTs will be contacted in due time regarding the registration process.
