How does patch testing work?

Alergy patch test on the back of a young womanDo you have skin allergies? Do you find yourself confused as to why you’re developing rashes and itching on the skin? Do you think you may have an allergy to something at work, school, or home and want some answers?

If this sounds like you, skin patch testing may be the solution for you. Patch testing is a way to test for skin allergies by placing small patches of potential allergens on your skin. This allows your dermatologist to determine which substances are causing your allergic reactions. Our team at the Skin and Beauty Center of California will discuss how patch testing works and what you can expect from the process.

How does patch testing work?

The patch testing process begins with your dermatologist reviewing your medical history and conducting a physical examination of your skin. Once they have a better understanding of your symptoms, they will select a variety of potential allergens to test. These allergens can include things like metals (nickel and chromium), fragrances, medications, plants, and latex. A small patch containing the allergen is then applied to your skin and left in place for 48 hours. During this time, you’ll need to avoid contact with water as much as possible so that the patch doesn’t come off. After two days, you return to the office and the patch test results are evaluated by our team at the Skin and Beauty Center. If you’re allergic to any of the substances tested, your dermatologist will provide you with a treatment plan to help manage your symptoms.

  • You’re experiencing unexplained rashes or itching on your skin
