Food Allergies: What Tests Can a Food Allergy Specialist Offer?

Scratch (Skin Prick) Test for Food Allergies



This common food allergy test identifies penicillin, food, and airborne allergies. A food allergist in Texas will prick your skin using a thin needle to deliver an allergen and check for an allergic reaction. Results are ready within 10-15 minutes.

Patch Test

Patch tests typically check for contact dermatitis. An allergy specialist at our food allergy treatment center in San Antonio will put a few drops of a specific allergen on your arm and cover it with a bandage or apply a patch infused with the allergen directly onto your arm. The specialist will then leave the patch on for 48-96 hours to see if it causes an allergic reaction.

Blood Test

Referred to as RAST tests or specific IgE tests, they check the levels of IgE antibodies in your blood to determine if you have food allergies. Food allergists recommend blood testing for patients who suffer from hives, rashes, and lesions, as well as those who cannot stop using medication long enough for a skin test.

Intradermal Skin Test

This food allergy test involves injecting an allergen into your skin and waiting to see if it causes a reaction. Intradermal tests will commonly check for venom allergies like penicillin or bee allergies.
