Allergen Prick Skin Test

What To Expect
After cleansing the skin on the upper back, the patient is pricked with approximately 50 local allergens to determine if the reaction is negative or positive to the allergen. The prick site will either disappear without any further sequelae or become a red and itchy bump. Those allergens which react are considered positive. Positive reactions indicate the presence of an allergy to this specific allergen. The allergens we test for are Trees, Weeds, Grasses, Molds and Environmentals (dog, cat, horse, dust, roach, mosquito).

Pre-Procedure

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 7 days prior to their skin test. CALL YOUR PHARMACIST TO CHECK ALL YOUR MEDICATIONS – PRESCRIBED AND OVER THE COUNTER....they will be happy to tell you if a medication blocks an allergy skin test. 

Post-Procedure

The area may be very itchy if there is a positive reaction. After the test we can apply a topical treatment to relieve the itching.
