Order Onion Allergy Test | Food AllergiesAn onion allergy test measures the amount of IgE antibodies directed at onion proteins in a blood sample.

About Onion Allergy Test | Food Allergies in Springville
Onion allergy is uncommon but documented, and it can occur alongside sensitivities to related plants such as garlic, leek, and chives.
The test uses a blood sample, which means the reaction being measured happens in the laboratory rather than in the body. A laboratory technique binds the sample to onion allergen and then detects any IgE that attaches to it.
Results are usually reported as a numeric value with a reference range, and some laboratories add a class score. Higher values are more consistent with sensitization, but the number alone does not confirm an allergy; the clinical history matters as much as the result.
Onion can appear in the diet in forms that are easy to overlook, including broths, spice blends, and processed foods. Identifying a specific trigger therefore often involves reviewing ingredients alongside test results.
