EU In Vitro Diagnostic Regulation
Regulation (EU) 2017/746 governing in vitro diagnostic medical devices in the EU.
Definition
Regulation (EU) 2017/746 (IVDR) sets out the regulatory framework for in vitro diagnostic medical devices placed on the EU market, replacing Directive 98/79/EC (IVDD). It introduces a risk-based classification (Class A, B, C, D) aligned with IMDRF principles and dramatically expands the role of Notified Bodies.What this means in practice
Under IVDD, roughly 8% of IVDs required Notified Body review. Under IVDR, that figure rises to roughly 80%. Regulation (EU) 2022/112 and Regulation (EU) 2024/1860 staggered transition deadlines through 2027-2029 to prevent supply shortages. Key new obligations include a Performance Evaluation Report (Annex XIII), Post-Market Performance Follow-up (PMPF), Summary of Safety and Performance (SSP) for Class C/D, EU Reference Laboratories for Class D, EUDAMED registration, and Person Responsible for Regulatory Compliance (PRRC) per Article 15. In-house (LDT) tests are permitted under Article 5(5) only with strict justification.Examples
- A SARS-CoV-2 PCR assay: Class D (detection of transmissible agent causing life-threatening disease).
- A HbA1c self-test: Class C (management of a chronic condition).
- A pregnancy self-test: Class C (self-testing).
- A clinical chemistry calibrator: Class B.
- •Assuming legacy IVDD CE certificates transfer automatically. They require a Notified Body application and quality system compliance before the applicable Article 110 deadline.
- •Under-scoping the Performance Evaluation - IVDR requires scientific validity, analytical performance, and clinical performance as three distinct evidence streams.
- •Missing the PMPF plan. It is mandatory even for Class B devices and must be reviewed annually (PSUR for C/D).
- •Treating companion diagnostics as generic IVDs. Article 48 requires consultation with EMA or a national medicines authority.
