Skin Prick Allergy Test ( used for airborne allergy, food allergy, drug allergy, insect allergy):

Testing is briefly placed on the forearms (for older children and adults) or back (for younger children) with  a small plastic device that applies a drop of the various allergens just under  the outer layer of the skin. This is not a shot and is well tolerated by patients of all ages (even infants) with minimal discomfort. The test sites are measured after a fifteen minute wait.

Intradermal Test:

 This test is performed by placing a small amount of allergen under the second layer of skin (similar to a tuberculosis test). This test is mainly used to test for specific allergies when the skin prick test fails to reveal a highly suspected allergy. It is not routinely performed.

Patch Test:

Patch testing involves applying patches that contain small amounts of various substances known to cause dermatitis. The patches are worn for two days at which time they are removed and the sites are measured for any reactions. The sites are viewed again in two days for any delayed reactions.


Spirometry is the  most common of Pulmonary Function Tests used to assess how well your lungs work. This test measures how much air you inhale, how much air you exhale and how quickly you exhale. This test is used to diagnose and monitor asthma and other conditions that affect breathing.

Oral Food Challenge Test:

If we believe that your risk of a severe food reaction is minor,we can do a food challenge.  A food challenge test is the definitive way to disapprove a food allergy, or see if your child has outgrown a food allergy. Your child will be given small but increasing amounts of the food and monitored very closely for any reactions. Medications will be given as needed due to any adverse reaction.

Immune Deficiency Evaluation:

In order to address the immune system, a detailed medical history will be performed along with the physical exam. Blood tests will be ordered and reviewed. Possible vaccines may be administered in order to test the immune response.


Allergists aren't just about giving allergy shots. The first line therapy for many allergic and sinus conditions involve avoidance, or medication treatment, or both. Medications range from antihistamines, nasal steroid aerosols, antihistamine nasal aerosols, antibiotics and inhaled medications.
