IVDR Performance Evaluation Explained: A Complete Guide for Manufacturers

Performance Evaluation is one of the most important requirements under the EU In Vitro Diagnostic Regulation (IVDR). Every manufacturer must demonstrate that their in vitro diagnostic medical device achieves its intended purpose through robust scientific validity, analytical performance and clinical performance evidence. This guide explains every stage of IVDR Performance Evaluation, including Performance Evaluation Plans (PEPs), Performance Evaluation Reports (PERs), Post-Market Performance Follow-up (PMPF) and how Performance Evaluation supports successful CE marking under Regulation (EU) 2017/746.

When Do You Need New Biocompatibility Testing for a Medical Device?

A material change, supplier switch, manufacturing transfer or design modification does not automatically require new ISO 10993 biocompatibility testing. Learn how manufacturers use Biological Evaluation Plans (BEPs), chemical characterisation, toxicological risk assessments and Biological Evaluation Reports (BERs) to determine whether existing biological evidence remains valid or whether additional testing is required under ISO 10993-1, the EU MDR and FDA expectations.

Why Notified Bodies Reject IVDR Performance Evaluation Reports: The Top 3 Mistakes Manufacturers Make

More than half of IVDR submissions face deficiencies during Notified Body review, with Performance Evaluation Reports (PERs) among the most common areas of concern. Learn the three critical mistakes that lead to PER rejections—including weak State of the Art justification, non-systematic literature reviews, and poor traceability between Scientific Validity, Analytical Performance, and Clinical Performance data—and discover how to build a compliant, audit-ready IVDR technical file.

Illustration of an IVD Essential Requirements Checklist showing the transition from the IVDD Essential Requirements to the IVDR General Safety and Performance Requirements (GSPRs) for in vitro diagnostic medical devices.

IVD Essential Requirements Checklist: Transitioning to IVDR GSPRs

The shift from the In Vitro Diagnostic Directive (IVDD 98/79/EC) to the In Vitro Diagnostic Regulation (IVDR EU 2017/746) represents a fundamental overhaul of how technical files are structured. Under the legacy Directive, manufacturers relied on an Essential Requirements Checklist to demonstrate safety and performance. Under the IVDR, this has been completely replaced by the General Safety and Performance Requirements (GSPRs) found in Annex I.

If you are updating a legacy device technical file or migrating a quality management system, you cannot simply copy and paste your old compliance arguments. The GSPRs require a much higher degree of clinical evidence, lifecycle risk tracking, and technical specificity.
