STRD0521: 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 check the accuracy of the standard solutions participants apply in routine analysis. 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 24 September 2021.

STRD0521: New deadline

The replacement sample sets for the proficiency test STRD0521 have been picked up by the logistics provider at BVL yesterday. The parcels are currently en route and are scheduled to arrive at their destination today or tomorrow. All participants expecting a replacement shipment are asked to confirm the sample receipt immediately using the form available here. The password has been provided by e-mail.

Considering the delay caused by the loss of the shipments by the logistics provider which now shifts the time alotted for the sample analysis into the summer holiday season, the EURL Berlin has decided to adjust the deadline for result submission. The new deadline will be 06 September, 2021.

STRD0521: Delay of shipments Update 14.06.2021

Unfortunately, a number of the sample sets shipped on Monday, 7 June, 2021, have not yet been delivered to the participants. We have contacted our logistics provider about the issue and have been informed, that they are dealing with an increased number of shipments. Additionally, they experienced issues with their software, but expressed that they were hopeful, that the delay caused by this should not exceed 24 hours. All participants in the proficiency test STRD0521 who have not yet received their sample set can however be assured that any influences on the analytical results arising from possible instabilities of the solutions will be accounted for in the performance assessment. For general information on the proficiency test, please refer to the following page: STRD0521.

Update 14.06.2021

Today, we have once more requested delivery services company to track the whereabouts of the parcels and will inform you of any news right away. Internally, we have discussed to wait until the end of this week and then try to re-ship the samples using a different logistics provider, if possible.

Some of the participants have also expressed concerns about the sample stability. We have conducted a short-term stability study and luckily the majority of the analytes does not show any significant instability, even when stored at room temperature for 28 days. Taking into account last week’s weather, we will also try to accommodate for any additional analyte loss due to the elevated temperatures. As the performance assessment will be conducted using consensus values, participant scores will not be influenced by a loss of analyte due to instability. We have also decided to prolong the deadline for the proficiency test due to the problems with the sample shipment. We have not determined a new date, yet but we will let you know right away.

Thank you for your understanding.

NSAI1120: Final Report

We are pleased to announce that the final report for the interlaboratory study on the analysis of NSAIDs in bovine and equine muscle NSAI1120 is now available. 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.

STRD0521: Postponement of the sample shipment

Due to unforeseen circumstances it is necessary to postpone the sample shipment for the proficiency test STRD0521. The new envisaged shipment date will be Monday, 7th June, 2021. In order to accommodate for the upcoming summer break, the time allotted for the analyses will also be extended. The deadline for result submission will be 30th July, 2021.

NSAI1120: Follow-up workshop (“special workshop”)

The workshop will take place on 1 June 2021 in the afternoon and is reserved for those who have participated in proficiency test NSAI1120.

Topics to be covered:

  • results of the interlaboratory study
