You may need an allergy test that uses a needle to inject a small amount of allergen extract into the skin on your arm (intradermal test). The injection site is examined after about 15 minutes for signs of an allergic reaction. Your dermatologist may recommend this test to check for an allergy to insect venom or penicillin.
Your allergy treatment plan may include medications, immunotherapy, changes to your work or home environment, or dietary changes. Ask your doctor to explain anything about your diagnosis or treatment that you don’t understand. With test results that identify your allergens and a treatment plan to help you take control, you’ll be able to reduce or eliminate allergy signs and symptoms.
