    Regulatory

    ISO 20916

    In one line
    International standard for Good Study Practice for clinical performance studies of IVDs using specimens from human subjects.
    Definition
    ISO 20916 is the IVD analogue to ISO 14155 - defining responsibilities, design, conduct, recording, and reporting of IVD clinical performance studies. EU IVDR Annex XIII references it as state of the art. The 2019 edition covers study planning, ethics committee review, informed consent, conduct, monitoring, data management and reporting for studies using specimens from human subjects. It is widely used to support the performance study requirements in IVDR Articles 57 to 77.
    Why it matters
    Required reading for any IVD sponsor designing performance studies under IVDR; closes a long-standing gap in IVD-specific GCP guidance.
    Common pitfalls
    • •Confusing ISO 20916 requirements with those of ISO 14155, which applies to non-IVD medical devices.
    • •Failing to establish a comprehensive clinical performance study plan as required by ISO 20916 clause 5.2.
    • •Neglecting to appoint a qualified principal investigator and clearly define their responsibilities according to ISO 20916 clause 4.2.
    • •Not adequately documenting adverse events and their causality assessment during an IVD clinical performance study.
    • •Applying ISO 20916 retrospectively to studies initiated before its publication without a clear justification or transition plan.

    Why compare MedTech terms side by side?

    MedTech terminology is full of pairs that look interchangeable but carry very different regulatory, clinical, and commercial consequences. Picking the wrong framework, pathway, or standard early in a project can add months to a submission, invalidate clinical evidence, or trigger an audit finding. Side-by-side comparison is the fastest way to surface those differences before they become costly mistakes.

    Each comparison on this page pulls from the same vendor-neutral, sourced definitions used throughout the MedTech Terms glossary. You see the one-line summary, the formal definition, why it matters in practice, common pitfalls, and the primary sources (FDA guidance, EU MDR/IVDR articles, ISO/IEC standards, MDCG documents, IMDRF principles) that back each entry. That makes the comparison defensible in regulatory strategy memos, design reviews, and submission narratives.
