Patch Testing for Skin Allergies
A form of an allergy skin test is the patch test. Patch tests don’t use needles. Instead, chemicals responsible for many allergic conditions are applied to patches, which are then placed on your skin. During a patch test, your skin can be exposed to dozens of potential allergens that may include latex, various medications, fragrances, preservatives, hair dyes, metals, resins, and more.
How Does Patch Testing Work?
During the test, you’ll wear the patches on your arm or back for 48 hours. During this time, you should avoid bathing and activities that cause heavy sweating. The patches are removed when you return to our office for your follow-up appointment. Irritated skin found at the patch site could indicate an allergy. Once we have these results, our team will work to make a treatment and avoidance plan with you.
Sometimes, we will examine the results again at 72 to 96 hours after application to detect any delayed reactions.
