MDCG guidance (by topic)
MDCG guidance is published by the Medical Device Coordination Group and represents the authoritative interpretation of MDR/IVDR requirements by the European Commission and member states. It is not legally binding but is followed by notified bodies and competent authorities and departing from it requires justification.

MEDDEV, NB-MED & Blue Guide
MEDDEV and NB-MED documents were produced under the old MDD/AIMDD/IVDD framework. While many remain relevant as interpretive guidance, they must be read in the context of MDR/IVDR requirements, which supersede them where inconsistent.
