Skin sensitizing potency classification according to GHS/CLP

GARDpotency is an in vitro add-on test to GARDskin for potency classification according to GHS/CLP. The assay can subcategorize sensitizers that have been identified by GARDskin (OECD TG 442E) into strong sensitizers (1A) or weak sensitizers (1B).


GARDpotency is included in the OECD Test Guideline Program (TGP 4.106). The ESAC considers that GARDpotency is a functional and valid test method ready for use in industrial screening applications.

GARDpotency is accepted by the ECHA and the results can be used as weight-of-evidence in REACH dossiers for sub-categorization of confirmed skin sensitizers into 1A or 1B according to the GHS/CLP system.
