Allergy Testing

 

Skin Prick Testing involves pricking the skin with allergic substances (allergens) so that the allergen goes under the skin’s surface. The health care provider then closely watches the skin for swelling and redness or other signs of a reaction. Results are usually seen within 15-20 minutes. A large panel allergic substances can be tested at the same time.

Intradermal (IDT) Skin Testing 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 used to find out if you are allergic to something specific, and results in a raised bump (wheal) and redness (flare) within a few minutes if allergic antibodies that are specific to that allergen are present in the skin.

The results of your tests are what the physician uses to determine what you are allergic to and what further treatment options might work best for you.
