Allergy Testing

There are several types of allergy testing that your E.N.T. Allergy specialist can perform to test you for allergies. The two most common types of allergy testing performed are skin tests and blood tests.


Skin Tests

First, a screening “prick” test is performed on the skin of the forearm. A small amount of certain allergens is put into the skin by making a small indentation or “prick” on the surface of the skin.
If you have allergies, a small amount of swelling, redness and itching occurs on the skin surface at the prick test site.

Next, based on the results of the initial screening “prick” test, more sensitive “intradermal” tests may be done to further evaluate your allergies. The intradermal skin test is performed on the upper arm where a small amount of allergen is injected within the skin.
The results of the intradermal test are measured and recorded several minutes after they are applied.  After the skin testing is complete, you and your physician will discuss the results and develop a treatment plan.

Skin tests are best performed in a physician’s office to assure the test results are read properly and to minimize the risk of rare, but potentially serious side effects.

Blood Tests

This type of allergy test is typically reserved for patients who are unable to undergo allergy skin testing, due to medication side-effects or skin conditions that may interfere with skin testing.

Blood tests are also used to test for Food allergies, such as to peanuts, when warranted by a patient’s history. Because the blood drawn for this type of allergy test is sent to an outside laboratory for processing, the results are not as rapidly available as with skin tests.
