About Onion Allergy Test | Food Allergies in Pacifica
Onion allergy is uncommon but can occur, and reactions may range from mild oral itching to more significant symptoms in sensitive individuals.
Onions belong to the Allium genus, which also includes garlic, leeks, and chives. People who react to onion may sometimes react to these related plants, though cross-reactivity is not guaranteed.
An IgE blood test works by exposing a sample of your serum to onion allergen and measuring the antibody binding that occurs. The result is reported as a level that, alongside your clinical history, can help a clinician assess sensitivity.
A positive result does not by itself diagnose an allergy. Some people have detectable IgE without symptoms, and some reactions involve non-IgE mechanisms that this test cannot detect. Only a qualified healthcare professional can interpret the result in context.
