Genotoxicity tests are used to screen for possible carcinogenic potential (short-term carcinogenesis tests).

Most carcinogens identified in humans have mutagenic properties in one or more experimental tests.

Numerous genotoxicity tests are available.

The most common tests encountered in chemical toxicology dossiers are :

gene mutation tests, including: a) in vitro tests on bacteria, such as the Ames test; b) in vitro tests on mammalian cells;
Clastogenesis tests, including: a) in vitro tests on mammalian cells, including the micronucleus test, and b) the micronucleus test in vivo on mice;...
