About Onion Allergy Test | Food Allergies in Estero
Specific IgE testing is a well-established laboratory method for investigating food-related allergic sensitization.
The test uses a blood sample to measure immunoglobulin E antibodies directed against onion proteins. IgE is the antibody class most closely associated with immediate allergic reactions, including hives, itching, and in some cases breathing difficulty.
Results are reported as a quantitative level of specific IgE. A detectable level indicates sensitization to onion, meaning the immune system has produced antibodies that recognize the allergen. Sensitization does not always translate into clinical symptoms, so results are interpreted alongside a person's history and other findings.
Onion is used widely in cooking, and reactions are sometimes attributed to other ingredients in a dish. Testing for onion-specific IgE can help clarify whether onion is a plausible trigger when symptoms occur after eating foods that contain it.
