​​Update 6-19-18  Hi Everyone, it's Dr Feigenbaum. WE ARE LIMITING our new patients for the summer.  Other than patients with chronic dermatitis who need patch testing and patients with asthma, we're limiting our new patients for now and You could try my great colleagues at Scripps Clinic Allergy Carmel Valley. My wonderful assistants have all just moved on to med school and I'm on my own right now in the office. I apologize if you've been waiting for a call back or email reply.  I should be able to catch up today,

I also just had an very exciting research finding which may allow the diagnosis and easy treatment for a condition not currently considered treatable.  As you can understand, I've been spending a lot of time on that.  I'm going to focus on that and vacation over the summer.  I'll continue to be available for current patients. 

Have a great summer.  Thanks!      Please communicate over patient portal or email.  My cell phone is 858 215 2201 if you need me urgently.

San Diego Food Allergy Test Specialist

(Food Allergy Testing, Food Intolerance, Gluten Sensitivity)

(Only your personal physician can provide you with medical advice.  If Dr. Feigenbaum is not your physician, the following should not be construed as medical advice.)


We perform comprehensive food allergy skin testing to: wheat, soy, cow's milk, peanut, tree nuts, fish, shellfish, fruit, vegetables, spices and other foods.  (Results in 15 minutes)


Allergy testing is considered by most Board-Certified Allergists to be the best way to identify your allergens.  Allergy testing is performed by scratching/pricking a small amount of allergen into your arm and seeing how much reaction it causes within 15 minutes.  The reaction is caused by the interaction between the allergens, allergy antibodies (IgE) and your immune cells (mast cells.)  Mast cells release histamine and other chemicals, causing itching, swelling, and redness at the site of the skin test.


Testing involves being “pricked” with several plastic Multitest devices.  Each white Multitest device has 8 skin testing prongs. Each prong is dipped in a well and each well contains a different food allergen.  15 minutes later, the results are written down and interpreted. Interpretation involves measuring the wheal and flare response to each of the allergens which were tested. Usually (but not always), the larger the wheal and flare response, the worse the allergy.  The wheal is the raised area of skin. The flare is the red area of skin surrounding the wheal.  Your testing sheet will indicate the size of the wheal and the size of the flare. For example, a result of 5/15 for alder tree indicates that there was a 5 mm wheal and a 15 mm flare.   
One of the testing prongs contains histamine, which is used as a positive control. Another prong contains saline, which is used as a negative control.
