Many people who experience itchy skin or unexplained rashes could have an underlying allergy. Patch testing is a way to establish if this is the case and, if so, what the patient is allergic to.
Contact Dermatitis Patch Test: What to Expect
Allergy patch testing is a valuable diagnostic tool for uncovering the cause of contact dermatitis. This test involves applying small amounts of suspected allergens to the skin using adhesive patches, which are left in place for 48 hours. Afterward, the skin is evaluated for reactions over several days to determine which substances are causing the irritation. Patch testing provides essential insights, enabling individuals to avoid specific allergens and manage their condition effectively.
