How are allergies diagnosed?

How are allergy tests done?

There are two ways to test for allergies. (The allergy team will suggest which method is best for your child.)

Skin tests: A small droplet of solution (which contains allergens) is placed on the skin, usually on the arm. Then a small fork-like instrument is used to apply pressure (a "prick") to the skin. Results are ready for examination in 15 to 20 minutes. Sometimes if the prick test is negative, another skin test may be performed. This test is called an intradermal skin test. A small needle is used to inject a small amount of allergen-containing solution just under the skin. Like the prick skin test, results are ready in 15 to 20 minutes.

RAST: This blood test is run weekly in the laboratory. (Results are usually available two days after the test is run.)
