Allergy Skin Testing in New York City
Allergy skin testing is the most sensitive form of allergy testing and continues to be the benchmark used by most allergists to diagnose the cause of allergies.
Our office uses a Skin Prick Method where the skin is pricked with a disposable plastic applicator that delivers a very small amount of allergenic extract into the skin surface. Each applicator tests eight (8) allergens and as many as six (6) applicators will be applied to your arms or back. No needles are used in this method.
You will be tested to a variety of airborne and or food allergens. These include pollens (from trees, grasses, & weeds), molds, dust mites, and animal dander.
The procedure takes less than 10 minutes to administer and the results are read approximately 15 to 20 minutes after the application of the allergen.
You will feel a pricking sensation during the application of allergen and will experience some itching. The testing staff will provide a cream to help relieve itching after the test results have been recorded. In rare cases, some local swelling may occur several hours after the skin tests are applied. Any positive reactions will gradually disappear over a period of 30 to 60 minutes.

- Dopamine: Intravenous infusion of dopamine may inhibit skin test responses.
