Patch Testing (For Allergic Skin Rashes)

Patch testing is a method used to identify whether a particular substance produces an allergic skin rash (contact dermatitis). During the patch test, a number of common allergy producing chemicals are placed on the skin and the skin is monitored over the course of a few days. Once the allergen is identified and if avoided, the rash usually clears. We have the North American, Cosmetic and Metal Series available.
