Study of the in vitro cytotoxicity testing of medical devices

★ ★ ★ ★ ★

6/19/2015 · The cytotoxicity test is one of the biological evaluation and screening tests that use tissue cells in vitro to observe the cell growth, reproduction and morphological effects by medical devices. Cytotoxicity is preferred as a pilot project test and an important indicator for toxicity evaluation of medical devices as it is simple, fast, has a high sensitivity and can save animals from toxicity.

Every medical device must be subjected to three common biocompatibility tests (often referred to as the Big Three): cytotoxicity, sensitization and irritation tests. Each test screens for the presence of toxic, leachable materials. Based on the category of the device, as many as five additional testing categories may be required (see test matrix ).
