Performance Evaluation

In order to put an IVD on the market or into operation, the basic safety and performance requirements relevant to the product must be fulfilled. To prove that the requirements have been fulfilled, a performance evaluation must be carried out. Regulations such as the IVDD or the new IVDR place high demands on the performance evaluation of in-vitro diagnostics. Why is this performance evaluation so important?

In-vitro diagnostics are important tools for obtaining information from human samples such as blood or tissue that allow conclusions to be drawn about, for instance, pathological or physiological processes in the body. This information is critical for the diagnosis and further treatment of the patient. A performance evaluation according to IVDD or IVDR must therefore ensure that the information obtained from the IVD is correct and accurate, and that it provides the intended clinical benefits.

The performance evaluation that precedes the market launch of a product is based on three pillars:

Because of our decade-long experience with in-vitro diagnostics, we can support manufacturers with a very extensive repertoire of products and services in the performance evaluation and in obtaining IVDR conformity for their products.
