Patch Testing

A patch test, unlike a skin injection or skin prick tests, does not scratch or puncture the skin. Instead, it tests delayed allergic reactions through patches places on your back to expose your skin to some 20 to 30 allergen extracts that commonly cause contact dermatitis. These patches are left on for two days and removed at your doctor’s clinic where they will inspect your skin for reactions to the various components. These may include anything from medications and hair dyes to metals and fragrances. Once you get your results, which they can tell you after taking the patches off, you’ll be able to make lifestyle changes to avoid unnecessary skin irritation.
