The micronucleus test is also known as the erythrocyte micronucleus assay, micronucleus assay or MN assay. In addition to this, it has also been referred to as the peripheral blood micronucleus test and the peripheral blood lymphocyte micronucleus assay. The Micronucleus Cytome assay is a more recent term that incorporates both micronucleus and cytome damage measurements. The test is a widely used genotoxicity test for detecting DNA damage and chromosome breakages. It is used to evaluate the mutagenic potential of various environmental agents, such as radiation, chemicals, and drugs. The versatility of the test has made it an integral component of several fields, including toxicology, genetics, and environmental health.
