Genetic toxicology studies are conducted early in the safety testing program of pharmaceuticals, medical devices, chemicals, food additives, etc. Charles River conducts its genetic toxicology studies in a tiered approach, starting with an Ames test and progressing to the conduct of mammalian cell and in vivo assays, which are designed to assess the toxicological relevance of any earlier observations.
