FAQ: MDR & IVDR

Quick answers to common questions about compliance, documentation and conformity assessment under EU MDR (2017/745) and IVDR (2017/746).

MDR (medical devices) — FAQ

Do all MDR devices need a Notified Body?

No. Many Class I devices can be self‑declared, but certain Class I subcategories (Is/Im/Ir) and higher classes require Notified Body involvement.

Is ISO 13485 mandatory under MDR?

MDR requires an appropriate QMS; ISO 13485 is the most common framework used to demonstrate this in practice.

What is the difference between Annex II and Annex III?

Annex II describes the structure and content of the technical documentation. Annex III focuses on post‑market surveillance (PMS) documentation, including plans and reports.

Do we need PRRC and EUDAMED?

PRRC is required under MDR. EUDAMED/UDI obligations depend on module availability and your role; we help you navigate the requirements.

Where do projects typically get stuck?

Common bottlenecks include misclassification, weak GSPR mapping, insufficient clinical evidence for the intended purpose/claims, and QMS not being audit‑ready for Notified Body review.

IVDR (IVDs) — FAQ

What is IVDR and when does it apply?

IVDR (EU 2017/746) is the EU regulation for in vitro diagnostic medical devices (IVDs). It applies to IVDs and related accessories placed on the EU market.

How are IVDs classified under IVDR?

IVDs are classified into Classes A, B, C and D based on intended purpose and risk. Correct classification sets your conformity assessment route and evidence expectations.

See IVD classification (IVDR).

What is performance evaluation (and how is it different from clinical evaluation)?

Under IVDR, performance evaluation is the framework for demonstrating scientific validity, analytical performance and clinical performance. It is not identical to MDR clinical evaluation, although the concepts are related.

See Performance evaluation (IVDR).

Do IVDR devices need a Notified Body?

Often yes. Many Class B/C/D IVDs require Notified Body involvement. The exact route depends on class and the selected conformity assessment procedure.

What are typical IVDR pain points?

Common issues include unclear intended purpose, underestimating evidence needs (especially clinical performance), and timelines for Notified Body availability.
