  • Ensuring MDR compliance in the EU is crucial for manufacturers.
  • Key steps include understanding MDR requirements, conducting gap analysis, developing a compliance strategy, updating technical documentation, implementing robust QMS, engaging with notified bodies, and maintaining continuous compliance.
  • Partnering with EU medical device consulting experts like Cliniexperts can streamline this complex process.


For manufacturers of in vitro diagnostic (IVD) devices seeking to market their products in the European Union, ensuring MDR compliance is a critical requirement. The EU Medical Device Regulation (MDR) has brought about significant changes in the regulatory landscape, and manufacturers must navigate these new rules to achieve and maintain compliance. Before divulging details, it is essential to understand IVD compliance.

Understanding IVD compliance

IVD (In Vitro Diagnostic) Compliance refers to the adherence of IVD devices to the regulatory requirements set forth by the European Union (EU) to ensure the safety and performance of these devices in the EU market. 

The EU IVDR (In Vitro Diagnostic Medical Device Regulation) 2017/746, which came into effect on May 26, 2022, replaced the In Vitro Diagnostics Medical Device Directive 98/79/EC and introduced significant changes to the regulatory framework for IVD devices.

IVD devices are classified into four classes based on their intended purpose and inherent risk:

Class of medical deviceRisk of medical device
Class Alow individual and public health risks
Class Bmoderate individual risks and potentially low public health risks
Class Chigh individual risks and moderate public health risks
Class Dhigh individual risks and high public health risks

Based on these classifications, manufacturers must apply for Medical device registration in EU with a proper justification. To ease the process for manufacturers, here is the step-by-step guide to understand IVDR and MDR compliance in detail.

Step Involved in IVDR and MDR compliance

To ease the process for manufacturers, here is a step-by-step guide to understand IVDR and MDR compliance in detail.

Understand the MDR Requirements

The first step for manufacturers is to gain a comprehensive understanding of the MDR requirements. The regulation has introduced more stringent rules for clinical evidence, post-market surveillance, and vigilance reporting.

Additionally, it has expanded the scope of regulated devices, including certain products that were previously unregulated.

Manufacturers should consult reputable sources, such as the European Commission’s official website or EU medical device consulting firms like CliniExperts for guidance regarding documents from notified bodies, to ensure they have a thorough grasp of the applicable requirements.

Conduct a Gap Analysis

Once the MDR requirements are well understood, manufacturers should conduct a gap analysis to identify areas where their existing processes and documentation may not meet the new standards.

This analysis should cover various aspects, including technical documentation, clinical evaluation, risk management, and quality management systems.

Develop a Comprehensive Compliance Strategy

Based on the gap analysis, manufacturers should develop a comprehensive compliance strategy that outlines the steps and resources required to achieve MDR compliance.

This strategy should include timelines, budget allocations, and responsible personnel for each task.

It is important to prioritize high-risk areas and address any critical gaps first. Manufacturers may also consider seeking EU medical device consulting services from experienced professionals to ensure their compliance efforts are on the right track.

Update Technical Documentation

Manufacturers must update their technical documentation to meet the MDR requirements. This includes revising the clinical evaluation, risk management documentation, and instructions for use (IFUs).

The technical documentation should demonstrate how the device meets the essential safety and performance requirements outlined in the regulation.

Implement a Robust Quality Management System (QMS)

A robust QMS is essential for MDR compliance. Manufacturers should review and update their QMS to align with the new requirements, including those related to post-market surveillance, vigilance reporting, and complaint handling.

The QMS should also incorporate processes for monitoring and maintaining compliance on an ongoing basis, as well as mechanisms for addressing any non-conformities or corrective actions.

Engage with a Notified Body

Under the MDR, most IVD devices require intervention from a notified body, which is an independent organization designated by the European Commission to assess and certify medical devices.

Manufacturers should select a notified body and initiate the conformity assessment process early on.

This process typically involves submitting technical documentation, undergoing audits, and obtaining the necessary certifications or approvals from the notified body.

Plan for Continuous Compliance

MDR compliance is an ongoing process, and manufacturers must be prepared to maintain compliance throughout the product lifecycle.

This includes monitoring and addressing any changes in regulatory requirements, updating technical documentation as needed, and implementing effective post-market surveillance and vigilance reporting processes.

Manufacturers should also plan for periodic audits and assessments by the notified body to ensure continued compliance and maintain their certifications.

By following these essential steps, manufacturers of IVD devices can navigate the complexities of the EU medical device registration process and achieve MDR compliance.

Failure to comply with the MDR can result in significant consequences, including product recalls, fines, and potential market exclusion.

Manufacturers are encouraged to seek guidance from regulatory experts, industry associations, and EU medical device consulting firms to ensure they are taking the appropriate measures to meet the MDR requirements and maintain compliance throughout the product lifecycle.
