When you have an allergy, your immune system overreacts to a substance (allergen) to which you are exposed. Allergy testing can provide useful information which an allergist can then use to treat your symptoms.
Different types of allergy tests provide information about different types of reactions, so it is important to see an expert to get the right tests and results.
Examples of Allergy Tests We Offer
Skin Prick Tests: A very small amount of each allergen is placed into your skin by making a small prick with a plastic device. Reactions appear within about 15 minutes. Skin prick testing is one of the most accurate ways to diagnose sensitivities to foods and airborne allergens (substances you breathe in, such as pollens, molds, or animal dander).
Intradermal Allergy Tests: A small amount of allergen is placed just under the skin, slightly deeper than with skin prick testing. This test is useful in diagnosing airborne particle, insect venom, and penicillin allergies.
Blood Tests: Blood tests are most useful when interpreted by an expert, and each test is very different. For example, a certain level of antibody against cow’s milk may be very significant, while that same level of antibody against peanut may not cause problems. Results must also be interpreted in the context of your history of ingestion of that food. Our providers have extensive training on how to interpret these tests to help you feel better and stay healthy.
Challenge Tests: These are the most accurate tests for allergies. Suspected food and drug allergies are the most common reasons a challenge is needed. To keep you safe, they are done in our office where we are equipped to quickly recognize and treat an allergic reaction.
Patch Tests: The suspected culprits for your reaction are placed onto your skin for about 48 hours. The results are then interpreted at least one day after removal. Patch tests are especially useful for skin reactions.
