The Committee on Mutagenicity has published A Strategy for Testing of Chemicals for Genotoxicity. The 2011 Guidance document recommends a staged approach to testing chemicals with no existing genotoxicity data. Stage 0 consists of preliminary considerations which include physico-chemical properties, toxicological properties, structure-activity relationships and information from screening tests. A “core-test battery” consisting of the Ames test combined with the in vitro micronucleus test is recommended for Stage 1 in vitro testing. For Stage 2 in vivo genotoxicity testing, the COM recommends the core tests of rodent micronucleus/chromosome aberrations assays for aneuploidy and clastogenicity, transgenic rodent gene mutation assay and the rodent Comet assay for DNA damage, but advises that the strategy be developed on a case-by-case basis in response to observations made at the earlier stages.
