Genotoxicity testing
A full evaluation of a chemical’s ability to induce the possible types of genetic damage involved in adverse human health outcomes (cancer, noncancer diseases involving somatic cell mutation, and heritable disease) includes tests that can detect gene mutation, chromosomal damage, and aneuploidy. A battery of tests is required to adequately cover all the genetic endpoints as no single test can provide information on all endpoints.
Vivotecnia offers comprehensive regulatory testing packages for chemicals which allow the full assessment of the genotoxic potential of your compound by detecting gene mutations, structural chromosomal aberrations, and numerical chromosomal abnormalities.
Evaluation of genotoxicity is an indispensable component in assessing substance safety, relevant in the context of EU and international regulations aimed at protecting human health and the environment.
Genotoxicity test results form the scientific basis for risk assessment and are used for classifying and labeling (C&L) chemical substances in the EU (see Directive 67/548/EEC and Regulation (EC) No. 1272/2008), and worldwide (see GHS), which apply in parallel with the REACH regulation (Regulation (EC) No 1907/2006).
According to REACH regulation, genotoxicity testing is tonnage triggered:
