Safe & Accurate Food Allergy Testing
Whether it be for safety, relief or any other reason, we’re here to help answer your questions and guide you through the process.
Adult & Pediatric Allergy Testing Services
At Texan Allergy & Sinus Center, we have the ability to perform food allergy testing and treatment on patients ages six months and older, for many common food allergens.
Options for food allergy testing include:
- Skin testing
- Blood testing
- Oral Food Challenge
Skin Testing for Food Allergies
Skin tests involve lightly pricking the skin with a tiny drop of the liquid food allergen. This is not painful. Some patients even think it tickles! After about 20 minutes, we’re able to see the results by measuring the reaction on the skin. This can range from a just a bit of redness to a raised “mosquito bite” looking bump. A raised bump generally indicates an allergic reaction and that treatment may be necessary.
Blood Testing for Food Allergies
Food allergy blood testing detects and measures the amount of allergen-specific antibodies in your blood. Test results are usually available in one to two weeks. Allergy blood testing is performed at an outside lab, and results are then sent to Texan Allergy & Sinus Center where they are reviewed by our team of allergy specialists.
Oral Food Challenge
An oral food challenge may be recommended if results from a food or blood test are uncertain. To confirm your food allergies, one of our allergists may recommend an oral food challenge. During this process, you’ll eat or drink small portions of a food in increasing amounts over a period of time to see if an allergic reaction occurs. This is always done under a doctor’s supervision.
While skin and blood testing are both accurate ways to test for food allergies, oral food challenges are known as the “gold standard” for diagnosing food allergies.
What to Expect During the Oral Food Challenge
Supervision – The challenge will be conducted by a board-certified physician, Dr. Stacy Silvers, who has been trained to manage oral food challenges and extensive food allergy therapy.
Safety – Emergency medications (including epinephrine, antihistamine and other emergency medications) will all be on hand and ready to be used, if needed.
Incremental doses – At the start of the challenge you’ll be given a very small, measured amount of the allergen and observed closely. Rest assured, full servings are not given on the first day. If no symptoms develop after 20 minutes, then another, slightly larger amount of the food will be given. This process will be repeated over the course of about three to four hours. The goal is to work up to a full serving size of the food you’re allergic to.
