Order Onion Allergy Test | Food AllergiesAn onion allergy is uncommon but real, and it belongs to the broader category of food allergies that can be evaluated with a targeted blood test. This test measures immunoglobulin E (IgE) antibodies specific to onion, giving a clear, objective signal about whether the immune system recognizes onion proteins as a threat.
About Onion Allergy Test | Food Allergies in Long Beach
Onion allergy testing looks for IgE antibodies that bind to onion allergens in a blood sample.
IgE is the antibody class most closely tied to immediate allergic reactions. When someone is sensitized to onion, their immune system produces IgE that recognizes specific proteins in the vegetable. A blood test detects those antibodies directly, without exposing the person to the food itself.
Symptoms of an onion allergy can include itching or tingling in the mouth, hives, stomach upset, and in more serious cases, breathing difficulty or a drop in blood pressure. Because onions are used in so many prepared foods, identifying the trigger can help people manage their diet with more confidence and avoid unnecessary restrictions.
Results are reported as a quantitative level of onion-specific IgE. A detectable level suggests sensitization, but sensitization and clinical allergy are not always the same thing. A clinician interprets the number alongside a person's history and symptoms to determine what the result means in practice.
