Diagnosis & Treatment Options
When an allergist feels that other testing has been inconclusive or a person may have outgrown a food allergy, an oral food challenge will be recommended. During this testing, you will ingest a small amount of the possible allergen and be observed for signs of adverse reaction. If no symptoms appear, you will receive larger doses until an allergy can be ruled out.
If you begin to have an adverse reaction such as flushing or hives, the food challenge will stop, and you will receive medication for symptoms if needed. Very rarely, a serious anaphylactic reaction results, which is why this challenge must occur under medical supervision of an Southern Nevada Allergy specialist.
Patients undergoing an oral food challenge must be in good health. The test should be postponed if you are just recovering from an illness, show signs of coming down with one, or are having a flare-up of asthma, hay fever, or eczema. Any of these health issues could alter or mask test results. Additionally, your allergy specialist will let you know when to stop taking antihistamines before the challenge. If you have any in your system for the test, results will be inaccurate.
Regardless of the results, knowledge is power. If a food allergy is confirmed, your doctor will discuss food avoidance strategies and medication options. If no adverse reaction occurs, you can check this food off your avoidance list and expand your diet accordingly.
