Comprehensive Allergy Testing for Accurate Diagnosis

Allergy testing is a diagnostic procedure that identifies what substances (allergens) trigger your allergic reactions. Tests like skin prick tests, blood tests, and patch tests expose your body to potential allergens in a controlled way to observe reactions. These tests help our allergists create accurate diagnosis and personalized allergy treatment plans.

We offer several types of allergy tests: Skin Prick Test (SPT) for quick results on environmental and food allergies; Intradermal Test for more sensitive detection of drug and venom allergies; Blood Tests (IgE) for patients who can't stop antihistamines or have skin conditions; and Patch Tests for diagnosing contact dermatitis and delayed skin reactions.

To prepare for allergy testing: stop taking antihistamines 3-7 days before your appointment (consult your doctor first); avoid allergy medications like Benadryl, Claritin, Zyrtec, and Allegra; don't apply moisturizers or creams to the test area on the day of testing; wear short-sleeved clothing; and bring a list of current medications. For food allergy testing, you may be asked to avoid certain foods beforehand.

The actual allergy test takes 20-60 minutes depending on the type. A skin prick test takes about 20-30 minutes including the waiting period for reactions. Blood tests only require a quick blood draw. Patch tests require three appointments: one to apply patches, one to remove them 48 hours later, and one to read final results 48-96 hours after removal.

Allergy testing is generally well-tolerated with minimal discomfort. Skin prick tests feel like a light scratch on the skin surface. Intradermal tests involve a tiny injection that may sting briefly. Blood tests feel like a standard blood draw. Patch tests involve no needles—just patches applied to your back. Most patients find the procedures virtually painless.

Food allergies involve the immune system and IgE antibodies, causing immediate reactions like hives, swelling, or anaphylaxis. Food intolerance (like lactose intolerance) affects digestion and causes symptoms hours later, like bloating or stomach cramps. Our allergy tests specifically detect IgE-mediated true food allergies, while intolerance testing requires different methods.

Yes! Pediatric allergy testing is safe and recommended for children with suspected allergies. Skin prick tests can be performed on infants as young as 1 month old. Blood tests are especially useful for young children since they only require one needle stick. Our board-certified allergists specialize in pediatric allergy care and make testing as comfortable as possible for children of all ages.
