Allergic contact dermatitis is an inflammation of the skin that occurs when a person is allergic to a substance that is touching his or her skin. Duke dermatologists use patch tests to determine which allergen is causing a patient's skin to be inflamed. In this test, small amounts of potential allergens are applied to patches that are then placed on a patient's skin. The dermatologist examines the patient's reaction to the substances to see if an allergy is present. Once the doctor has determined the allergy, patients are able to avoid that substance and receive medication for any current rash. A consultation may be necessary prior to the placement of patch tests.
