Allergy Skin Test Intradermals

What To Expect:
This procedure is performed on the upper arm and is used ONLY FOR SUBLINGUAL IMMUNOTHERAPY PRESCRIPTIONS. It entails using common allergens and allergen mixes (mixes are not used in prick testing) in order to determine problem allergens and dosing for sublingual immunotherapy. This test CAN NOT BE USED FOR IMMUNOTHERAPY VIA INJECTION.

The test is performed by cleansing the skin of the upper arm with alcohol, which is allowed to dry, and is then marked for allergen placement with a pen. A miniscule amount of allergen is then injected under the dermis of the skin with the thinnest and smallest of needles (similar to a beading needle). The needle is inserted ever so slightly under the skin at the time of injection such that the tip is still visible while in the skin. Injecting the allergen intradermally creates a small bump similar to a mosquito bite which will either disappear without any further sequelae or will become red and itchy with time. Those that react are considered positive for the allergen.

The patient must not consume any antihistamines such as Allegra, Zyrtec, Benadryl, Clarinex, Claritin, Alavert or Cold preparations, nor any H2 blockers such as Zantac, Pepcid or Tagamet at least 5 days prior to their skin test. CALL YOUR PHARMACIST IF IN DOUBT....they will be happy to tell you if a medication blocks an allergy skin test.

The area may be very itchy if there is a postive reaction. After testing, we can apply a topical treatment to relieve the itching. We will ask the patient to read the test on their arm at 24 hours and 48 hours (similar to a TB Test). This is especially important for mold testing as molds are notorious for producing DELAYED REACTIONS.
