    Notified Body Scrutiny (IVDR Class D)

    Additional expert-panel review of a notified body's assessment for certain novel or high-risk Class D devices before certification.

    Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed July 25, 2026

    Definition

    Article 48(6) requires the notified body assessing a Class D device to notify a designated expert panel of its Performance Evaluation Assessment Report (PEAR) where no CS exist for the device, the device is the first of its kind, or the CS have been recently revised. The expert panel may deliver a scientific view within 60 days that the notified body must duly consider.
    What the regulation says
    Article 48(6) and Article 106 detail the composition and functioning of the expert panels and the procedure by which their scientific views feed back into the notified body's decision.

    What this means in practice

    Scrutiny is a checkpoint intended to raise consistency across notified bodies for the highest-risk IVDs (HIV, HCV, blood grouping, novel pathogen assays). It borrows the mechanism of MDR Article 54 CECP scrutiny for implantable Class III devices.
