Oral allergy to food

Skin-prick testing is easy to do and results are available in minutes. Different allergists may use different devices for testing. Some use a " bifurcated needle ", which looks like a fork with two prongs. Others use a "multitest", which may look like a small board with several pins sticking out of it. In these tests, a tiny amount of the suspected allergen is put onto the skin or into a testing device, and the device is placed on the skin to prick, or break through, the top layer of skin. This puts a small amount of the allergen under the skin. A hive will form at any spot where the person is allergic. This test generally yields a positive or negative result. It is good for quickly learning if a person is allergic to a particular food or not, because it detects IgE. Skin tests cannot predict if a reaction would occur or what kind of reaction might occur if a person ingests that particular allergen. They can, however, confirm an allergy in light of a patient's history of reactions to a particular food. Non-IgE-mediated allergies cannot be detected by this method.

If you or your child experience a reaction beyond the mouth area after eating a fresh fruit or raw vegetable, that food could be considered a risk for anaphylaxis , a serious reaction that is rapid in onset and may cause death. In one study, researchers found that oral allergy syndrome symptoms may progress to systemic symptoms in nearly 9 percent of patients and to anaphylactic shock in percent of patients. Consult with your allergist for more information and to determine whether you should carry an epinephrine auto-injector to treat such potential severe reactions.
