STRD1023: Registration is now open

Following up on the positive feedback received for the first proficiency test on precision and accuracy in the analysis of standard solutions organised in 2021, the EURL Berlin is please to announce a new round of this format for October 2023. All eligible laboratories will receive the official announcement by e-mail later today. Due to the limited number of test items available, the EURL Berlin reserves the right to limit the number of participants. Please find more details on the proficiency test here.

Revised EURL guidance document on the quality control during routine analysis

The EURL guidance document on the quality control during routine analysis (ongoing performance verification) is now available as version 1.2. Taking into account the feedback received from the NRLs, a section on the selection of representative analytes on which to monitor the method performance has been introduced. The EURLs hope that this information will be helpful to the laboratories active in the field of the analysis of residues of veterinary medicinal products. The provision of constructive feedback for example during the EURL workshops or by e-mail is encouraged and helps to improve the practicality of the guidance documents.

BVL: EURL Workshop 2023

We are pleased to announce that the EURL workshop organised by the BVL is planned for 3-5 May 2023 as an on-site event in Berlin. We are very much looking forward to meeting everyone in person once again and hope for fruitful discussions. Information on the registration and a preliminary programme will be made available in April.

NIIM1122: Preliminary Report

The preliminary report for the proficiency test NIIM1122 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 porcine muscle. 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 30 January 2023.

EURL Guidance Document on Standard Addition published

In order to support the harmonised interpretation and the implementation of the Commission Implementing Regulation 2021/808 laying down requirements for the performance of methods for the analysis of veterinary drug residues, COM has asked the EURLs to provide guidance documents dealing with specific aspects which might require supplemental information. Now, the EURL Guidance Document on Standard Addition has been finalised and is available as of today.

Several laboratories had expressed a need for additional guidance on the application of the standard addition approach respecting the provisions of CIR 2021/808. In response, a working group tasked with drafting an EURL Guidance Document on this topic was formed. The working group members are: Ingrid Elbers (EURL WFSR), Andreia Freitas (NRL Portugal), Murielle Gaugain (EURL ANSES), Ulrike Mülow-Stollin (EURL BVL), Christelle Robert (NRL Belgium) and Ivana Varenina (NRL Croatia).

The first draft was circulated within the laboratory network this autumn. The NRLs’ feedback was collected via an online form and expressed during the WFSR workshop in November. The working group members would like to sincerely thank all of you for your suggestions and remarks. The feedback was considered for the version 1.1 of the Guidance Document which you may find attached to this e-mail. The colleagues of the EURL Wageningen also kindly created an Excel spreadsheet which may be used for calculations necessary for the multiple standard addition approach outlined in the Guidance. This Excel file has been validated according to WFSR procedures regarding the validation of spreadsheets.

Although the guidance document represents the EURLs’ interpretation of CIR (EU) 2021/808 and is meant as a support for all laboratories, it is not seen as mandatory to follow. Other approaches are possible, if they provide plausible and comparable results. However, we sincerely hope that you will find the document useful. As is the case with all EURL Guidances, the document is to be understood as non-static, meaning that should you notice aspects which might require further information, you are welcome to submit your remarks to the EURLs for review.
