EU Regulation on in vitro diagnostic medical devices (IVDR)

The IVDR, which will regulate all in vitro diagnostic medical devices (IVDs) from May 2022 onwards, will have a major impact on IVD manufacturers as well as diagnostic laboratories. To aid laboratories from the ESLHO networks with their preparations for the IVDR, including compliance to the IVDR requirements for in-house devices, ESLHO provides information and support in the form of lectures, symposia, publications and a dedicated web page.


ESLHO is a Specialized Working Group of the European Hematology Association. At the annual EHA Congress, ESLHO presents its innovations in the special EHA-SWG sessions.

New Perspective on implementation of the IVDR in diagnostic labs

At the EHA2022 Congress, an EHA-IVDR session was held in which the local implementation of the IVDR was discussed. This resulted in a publication in HemaSphere with the title: “Experience With IVDR Implementation in Three Diagnostic Laboratories: Messages to EU Health Institutions, Diagnostic Healthcare Payers, and Authorities.” ESLHO, which is one of the Specialized Working Groups of the European Hematology Association (EHA), has contributed to both the 2022 EHA-IVDR session and this recent publication. The perspective summarizes the EHA-IVDR session, in which laboratory professionals from three different EU countries shared their experiences with local implementation of the IVDR. Messages to different stakeholders, aimed at supporting further IVDR implementation, are included at the end of the publication.
