Identification of Skin Sensitizers

Substances with the potential to cause allergic contact dermatitis (ACD) are skin sensitizers; the process by which they cause ACD is skin sensitization. Non-animal approaches to identify potential skin sensitizers are becoming widely accepted. NICEATM, ICCVAM, and ICCVAM agencies have been at the forefront of advancing these non-animal approaches.

Defined Approaches to Identify Potential Skin Sensitizers

A defined approach uses input data and a data interpretation procedure to identify potential skin sensitizers. NICEATM and ICCVAM have developed and evaluated defined approaches. Read More

ICCVAM Evaluations of the Murine Local Lymph Node Assay (LLNA)

The LLNA uses fewer animals and causes less pain than tests that use guinea pigs for identifying skin sensitizers. ICCVAM evaluated the LLNA for a number of applications. Read More
