The European Commission offers a series of documents to assist stakeholders in implementing IVDR and MDR.

The guidance documents have been endorsed by the Medical Device Coordination Group (MDCG) and aim at a uniform application of MDR and IVDR within the EU. These documents can be found at: Guidance - MDCG endorsed documents and other guidance.

The website of the European Commission provides information on the national requirements for IVD performance studies and the pilot coordinated assessment.
