Allergen Patch Testing

Allergen patch testing is a medical procedure used to identify specific substances that may cause allergic skin reactions. During the test, small amounts of various allergens are applied to the skin on adhesive patches, usually placed on the back. The patches remain in place for 48 hours to allow the skin to react. After removing the patches, a healthcare provider examines the skin for signs of allergic reactions, such as redness or swelling. This test helps diagnose contact dermatitis and guide treatment by avoiding identified allergens. It’s a crucial step in managing allergies and skin health.
