BETA0622: Postponement of sample shipment

We regret having to inform you that, due to a strike by our carrier TNT/FedEx we have to cancel the shipment of the proficiency test samples which had been scheduled for 14 June 2022. Unfortunately, the strike is for an indefinite period of time, so that we are unable to give you a new shipment date at the moment. In any case, the period allowed for the analysis of the PT samples will be prolonged respectively. We hope to be able to provide you with more information soon.

STRD0521: Final Report

We are pleased to announce that the final report for the interlaboratory study on accuracy and precision in the analysis of standard solutions – STRD0521 – is now available. Thank you for your patience. Please retrieve your copy from the FIS-VL. We would be grateful if you would fill out the follow-up questionnaire available here. All participants have received the password via e-mail.

NIIM1021: Delay in the publication of the final report

Due to a shortage of staff the publication of the final report for the proficiency test NIIM1021 has to be postponed to June 2022.Following up on the preliminary report, only minor changes were necessary and therefore, the z-scores will only change minimally for the final report. Any specific questions regarding the proficiency test or the analysis of nitroimidazoles in plasma and milk in general can be submitted to the EURL Berlin.

2022 EURL Berlin Proficiency Tests

The EURL Berlin is planning to organise two proficiency tests in 2022. Scheduled for the first and second quarter is a proficiency test on the determination of beta-agonists in bovine urine (BETA0422). Participating laboratories will be provided with 3-4 incurred samples containing an unknown number and amount of beta-agonists. The test items are projected to ship in April.

The EURL Berlin’s second PT in 2022 is planned for the third and fourth quarter. As regards the substance group of interest, there are currently two options. The PT will either deal with the analysis of coccidiostats in liver or the analysis of nitroimidazoles in porcine muscle. The laboratory network will be informed which PT will be organised as soon as a decision has been taken. Further details on all PTs will be announced in due time.

NIIM1021: Preliminary Report

The preliminary report for the proficiency test STRD0521 is now available on the FIS-VL. The objective of this proficiency test was to allow the participants to assess the performance of their routine methods for the analysis of nitroimidazoles in plasma. Additionally, a milk sample was supplied, which participants were asked to analyse using their routine method for the analysis of milk, or, if no such method was available, their analytical method for plasma. All participants are asked to have a look at their results and communicate any deviations from the results they submitted to the EURL Berlin by 15 December 2021.
