Designation of EU reference laboratories for high-risk in vitro diagnostic medical devices

On 5 December 2023, the European Commission adopted an implementing act designating 5 EU reference laboratories (EURLs) in the field of in vitro diagnostic medical devices (IVDs). These EURLs will be involved in conformity assessment of high-risk (class D) IVDs as well as carry out certain advisory tasks. 

Commission Implementing Regulation (EU) 2023/2713 of 5 December 2023 designating European Union reference laboratories in the field of in vitro diagnostic medical devices

The designated EURLs together cover the following categories of class D IVDs:

  • Hepatitis and retroviruses
  • Herpesviruses
  • Bacterial agents
  • Respiratory viruses that cause life-threatening diseases


The implementing act includes transitional arrangements to allow the EURLs to form a network and harmonise their working methods, and for manufacturers and notified bodies to adapt their processes to include EURL testing. The EURLs are expected to take up their tasks in conformity assessment of devices on 1 October 2024.

The act includes provisions to minimise disruption to ongoing conformity assessment processes. In particular, only new applications submitted to notified bodies after the end of the transition period will be subject to performance verification by the EURLs. On the other hand, batch testing of devices already CE-marked under Regulation (EU) 2017/746 will begin after the end of the transitional period to ensure appropriate control of those IVDs.

More information on the background and the selection procedure of the EURL can be found here.

What does this mean to you?

Finally, the first EURLs have been designated under IVDR. This is important news for all Class D manufacturers.
