For a skin test, the doctor uses small drops of allergen extracts that include some wheat proteins. The doctor puts the allergens into contact with the patient’s skin. After 15 minutes, he inspects the patient for any symptoms of allergic reactions. If the doctor notices a red, itchy bump, the doctor concludes that the patient has a wheat allergy, as Mayo Clinic indicates.

In case a patient has a skin condition that makes a skin test impossible, the doctor may order a comprehensive blood test, as Mayo Clinic advises. Through the test, doctors look for certain allergy-causing antibodies in the blood, especially those caused by allergens such as wheat. If the physician discovers these antibodies, the chances are that the patient has a wheat intolerance.

A food diary keeps a detailed record of eating habits and the symptoms developed after eating certain foods. In an elimination diet, the doctor recommends that the patient eliminates certain foods, especially those that contain allergens such as wheat. If the patient recovers after removing wheat from the diet, it is possible that he has a wheat allergy, as Mayo Clinic observes.
