We are experts at the two main methods of allergy testing in Gainesville, Florida. These include the testing of the skin (prick or intradermal) and testing of the blood. Both skin and blood tests are very good, but we usually recommend skin testing since we think it is more accurate than blood testing.
Allergy testing will identify specific substances to which an individual patient will react. Allergy tests are done to determine what the individual is allergic to before starting allergy drops (sublingual immunotherapy, also called SLIT) or allergy shots. However, it is also possible for patients to have allergy tests to learn which substances to avoid. Whether you have seasonal (part of the year) or perennial (all year) allergies our goal is to develop a treatment plan for you!
How the Test is Performed
The skin prick test involves:
- Placing a small amount of substances that may be causing your symptoms on the skin, most often on the forearm, upper arm, or back.
- The skin is then pricked so the allergen goes under the skin’s surface.
- The health care provider closely watches the skin for swelling and redness or other signs of a reaction. Results are usually seen within 15 to 20 minutes.
- Several allergens can be tested at the same time.
The intradermal skin test involves:
- Injecting a small amount of allergen into the skin.
- The health care provider then watches for a reaction at the site.
- This test is more likely to be used to find out if you are allergic to bee venom or penicillin. Or it may be used if the skin prick test was negative and the provider still thinks that you are allergic to the allergen.
