Patch testing is not the same as allergy prick testing. Allergies to dyes, fragrances, chemicals, metals, and personal care products that come into direct contact with the skin often result in a type of skin irritation known as contact dermatitis. A person can develop an allergy to a product at any time, even to products that have been used for many years.

The patch test consists of 70 of the most common chemicals/products. You may also bring a few of your own products to test. The patches are placed across your upper and middle back and left in place for 48 hours. Patch test results are read at 48 hours and 72 hours. At the 72-hour patch test reading, you will meet with your allergist to review the test results and create a specialized treatment plan.
