Quick answer
The Onion Allergy Test measures immunoglobulin E antibodies against onion. Onion is a staple ingredient in many kitchens, and allergy to it is uncommon, though reactions can occur and are sometimes linked to cross-reactivity with other alliums or pollen. The test is typically ordered when symptoms follow onion intake or when a wider food panel is being reviewed.
What this test measures
Onion belongs to the allium family along with garlic, leek, and chives. Allergy to onion is relatively rare, and some people who react to raw onion tolerate it when cooked, since heating changes some proteins. Reactions may appear as skin symptoms, digestive upset, or in more serious cases, breathing difficulty.
The test measures onion-specific IgE in a serum sample. A single blood draw provides the sample, and the laboratory reports a quantitative antibody level or reactivity class. When the test is part of a food panel, each allergen is reported separately, which helps show whether reactivity extends to related alliums.
A positive result indicates sensitization, not a guaranteed allergy. Some people have antibodies without symptoms, and others react only to certain forms of the food. A healthcare provider interprets the result with the person's reaction history and any other allergy testing that was performed.
