less than 5 minutesReplace, Reduce, Refine - How Lhasa Limited are supporting the 3Rs
Last year, a revolutionary guideline on Defined Approaches for Skin Sensitisation (OECD GL No.497) was released by the OECD. It is the first ever guideline that recommends the use of a combination of non-animal methods to predict whether a chemical can cause skin allergies. Since the publication of this guideline, Lhasa Limited have developed ‘Skin Sensitisation Defined Approach ITSv1 1.0’ – a web application containing one of the defined approaches published by the OECD, which provides hazard and potency skin sensitisation predictions without the use of animal tests. This tool is a step towards full replacement of animal testing for skin sensitisation and employs the 3Rs principle.
