Special MDR Requirements for In Vitro Diagnostic Medical Devices (IVDs)
The Medical Device Regulation (MDR) 2017/745 has introduced new requirements for medical devices, including in vitro diagnostic medical devices (IVDs), to ensure their safety and performance. IVDs are medical devices that use reagents or other substances to diagnose diseases or conditions. They play a crucial role in patient diagnosis and treatment planning. The MDR provides specific requirements for IVDs, which are discussed in this article.
Key Changes for IVDs under the MDR
The MDR has introduced several key changes for IVDs, including:
Classification: IVDs have been reclassified based on their level of risk.
EU Declaration of Conformity: Manufacturers must ensure that their IVDs comply with EU directives and regulations.
Labelling and Instructions for Use: IVDs must be accompanied by clear labelling and instructions for use.
Detailed Requirements for IVDs
The MDR sets out specific requirements for IVDs, which can be broken down into the following key areas:
Risk Management
Manufacturers of IVDs must implement a risk management process to identify and mitigate potential risks associated with their devices.
This includes identifying hazards, assessing and evaluating these hazards, and implementing measures to reduce or eliminate them.
Detailed Requirements for Risk Management
Here are some detailed requirements for risk management in IVDs:
Risk Identification: Manufacturers must identify potential hazards associated with their IVDs. These can include biological risks (e.g., contamination), physical risks (e.g., incorrect calibration), and chemical risks (e.g., reagent toxicity).
Risk Assessment: Manufacturers must assess the likelihood of each identified hazard occurring, as well as its potential impact on patient safety.
Risk Evaluation: Manufacturers must evaluate the level of risk associated with each hazard, taking into account factors such as the severity of the potential harm and the likelihood of occurrence.
Risk Reduction: Manufacturers must implement measures to reduce or eliminate the identified hazards.
Labeling and Instructions for Use
IVDs must be accompanied by clear labeling and instructions for use. This includes:
Labelling Requirements: IVDs must have clear labeling that provides essential information about their use, performance, and limitations.
Instructions for Use: Manufacturers must provide instructions for the proper use of their IVDs, including any necessary calibration or maintenance.
Detailed Requirements for Labelling and Instructions for Use
Here are some detailed requirements for labeling and instructions for use in IVDs:
Labelling Content: The labelling must include information such as:
Device name and model number
Purpose of the device
Performance characteristics (e.g., sensitivity, specificity)
Limitations of the device
Any necessary warnings or precautions
Instructions for Use Content: The instructions for use must include information such as:
Preparation and setup procedures
Sample handling and collection procedures
Testing and calibration procedures
Maintenance and troubleshooting procedures

Q: What is the purpose of reclassifying IVDs under the MDR?
A: The reclassification of IVDs was introduced to better reflect their level of risk. This change aims to ensure that high-risk devices receive appropriate regulatory attention and oversight.
Q: How do manufacturers implement a risk management process for IVDs?
A: Manufacturers must identify potential hazards associated with their IVDs, assess and evaluate these hazards, and implement measures to reduce or eliminate them.
Q: What information must be included in the labeling of IVDs?
A: The labeling must include essential information about the use, performance, and limitations of the device, such as device name and model number, purpose of the device, performance characteristics (e.g., sensitivity, specificity), limitations of the device, any necessary warnings or precautions.
Q: What is the importance of instructions for use in IVDs?
A: Instructions for use are essential to ensure that healthcare professionals can properly operate and maintain their devices, thereby reducing the risk of errors and adverse events.
Q: How do manufacturers ensure compliance with the MDR requirements for IVDs?
A: Manufacturers must implement a quality management system (QMS) that ensures compliance with the MDR. This includes identifying potential risks associated with their devices, assessing and evaluating these hazards, and implementing measures to reduce or eliminate them.
The MDR has introduced several key changes for IVDs, including reclassification, EU Declaration of Conformity, labeling, and instructions for use. Manufacturers must implement a risk management process and provide clear labeling and instructions for use to ensure the safety and performance of their devices. This article provides detailed information on the special requirements for IVDs under the MDR.
Note: The information provided in this article is intended as general guidance only. Manufacturers should consult with regulatory experts to ensure compliance with the MDR.
