Allergy testing identifies allergens, like mold, pet dander, bee stings and peanuts, that can cause allergies. During a skin prick test, a healthcare provider introduces allergens into your skin to check for a wheal (raised mark), rash or other reactions. Blood tests can check for IgE antibodies. The results can help you take steps to manage allergies.
Healthcare providers perform allergy tests to determine whether your immune system overreacts to certain substances (allergens). If you have an allergic reaction, it means you have an allergy. People can be allergic to things in the environment like mold, pollen and pet dander. Some people have allergic reactions to bee stings or latex. People with food allergies may not be able to tolerate peanuts, milk or soy.
