IVDR Compliance
CE marking is mandatory for all in vitro diagnostic (IVD) devices placed on the European market. It signifies that the device complies with applicable EU legislation and can be legally commercialized across the European Economic Area (EEA).
Previously regulated under the In Vitro Diagnostic Medical Devices Directive (IVDD 98/79/EC), IVD devices are now subject to the more stringent requirements of the In Vitro Diagnostic Medical Devices Regulation (IVDR 2017/746), which became fully applicable in May 2022.
Under the IVDR, manufacturers must meet enhanced standards related to safety, performance, clinical evidence, and post-market surveillance. The new regulation also significantly expands the scope of IVDs requiring Notified Body involvement, making expert regulatory support more critical than ever.

IVD Classification under the IVDR
The In Vitro Diagnostic Regulation (IVDR 2017/746) introduces a new, risk-based classification system for IVD devices, replacing the previous self-certification model under the IVDD. Devices are now classified into four classes — A, B, C, and D, based on their intended use and potential risk to patients and public health.
Class A
Low individual and public health risk (e.g., laboratory instruments, specimen receptacles)
Class B
Moderate individual risk, low public health risk
Class C
High individual risk, moderate to high public health risk (e.g., self-testing devices, infectious disease tests)
Class D
High individual and public health risk (e.g., HIV, hepatitis testing)
