Skin testing includes several procedures to identify the substances causing your allergies (allergens). When performing skin testing, the team at Allergy & Asthma Institute of Southeast Michigan exposes your skin to your potential allergens and watches for signs of an allergic reaction.
Your provider begins with a skin prick test, which can detect nearly every type of allergen except those that come into contact with your skin. If needed, they may do an intradermal skin test.
Your provider marks your skin so they can keep track of the allergens being tested. Your provider uses a small disposable plastic device dipped in the allergen to gently prick the skins surface. They can test for many allergens at once, so they repeat that process for each.
You relax in the office for 15 minutes, then your provider checks for skin reactions to the allergens. If a red bump develops, you’re allergic to that substance. Your provider evaluates the size of the skin reaction to estimate your sensitivity to the allergen.
Your provider injects a tiny amount of allergen in the skin’s surface. Like a skin prick test, they closely watch for a reaction to learn if you’re allergic to that allergen.
The team at Allergy & Asthma Institute of Southeast Michigan often does an intradermal skin test for insect venom, penicillin and environmental allergens. They also use it to verify the results if your skin prick test was negative but your symptoms indicate you have an allergy.
Contact allergens activate an immune response when they come into direct contact with your skin. This includes many possible allergens, ranging from poison ivy to latex, nickel, soaps, and chemicals in skin care products.
To identify contact allergens, your provider performs a skin patch test. They put allergens on a self-adhesive patch and place the patch on your back.
You wear the patch for two days (being careful to keep it dry) before returning to the office so they can check for skin reactions.
