Peer reviews of ecotoxicity and human health test methods


Peer Review of the Comet assay validation exercise.  The international validation of the in vivo Comet assay was led by Japan. The experimental phases started in 2006 and the validation reports below (including pre validation report and validation report) were peer reviewed in January and February 2013. The validation and the peer review reports were endorsed by the WNT  in April 2013. A Test Guideline is currently under development.
