Cytotoxicity is the most common test category utilized in ensuring the safety of medical devices.  Used as an important screening tool as well as a significant biological endpoint for submission requirements, these tests assess the cytotoxic potential of a device or material to inhibit cell growth or cause cell death. These in vitro assays can be performed in both qualitative and quantitative methods. The appropriate test method is selected based on the nature of the sample to be evaluated, the potential site of use and the nature of use.
