EU IVDR: Class C IVD Devices Face 2026 Compliance Deadlines

In vitro diagnostic manufacturers are approaching an important milestone under the

European Union’s In Vitro Diagnostic Regulation (IVDR). By May 26, 2026, Class C IVD

devices must comply with the new IVDR requirements, marking the end of the transition

period for this category. This deadline will affect many moderate risk tests, including

infectious disease assays, companion diagnostics, and genetic tests.

Manufacturers that currently hold legacy CE certificates under the old In Vitro Diagnostic

Directive (IVDD) must transition their products to the IVDR framework by this date. To

remain on the EU market, these companies need to submit applications to a Notified Body,

update their technical documentation, and demonstrate compliance with stricter

performance evaluation and post market surveillance requirements.

The IVDR significantly raises the bar for evidence and documentation. It requires

continuous performance evaluation, clinical evidence, and a proactive approach to risk

management. The role of Notified Bodies has expanded, and the number of available bodies remains limited, which means companies that delay their submissions may face review backlogs and potential market interruptions.

To stay on track, manufacturers should be completing gap assessments and engaging with

Notified Bodies as early as possible in 2025. Updating labeling, data management systems,

and vigilance reporting processes will also be necessary to meet the 2026 expectations. For

companies that operate globally, aligning IVDR compliance efforts with FDA or other

international requirements can help streamline regulatory operations.

Class C IVD manufacturers cannot afford to wait. The 2026 compliance deadline represents

a pivotal moment for market access and regulatory credibility in Europe. Those that act now

will be positioned to maintain business continuity and build stronger, more resilient quality

systems for the future.
