IgE is the class of antibody most closely associated with immediate allergic reactions, so its presence can help a clinician evaluate whether onion is a trigger for symptoms.
About Onion Allergy Test | Food Allergies in Normal
The test measures antibody activity rather than the physical reaction itself, which makes it a useful piece of a broader allergy workup.
Onion belongs to the Allium genus, a group that also includes garlic, leek, chives, and shallot. Reactions to onion are uncommon compared with many other foods, but they are reported, and they can occur even when the onion is cooked.
An IgE blood test works by exposing a sample of serum to onion allergen and measuring how much specific antibody binds to it. A positive result indicates sensitization, meaning the immune system has produced IgE that recognizes onion proteins; it does not by itself confirm that eating onion will cause symptoms.
Because sensitization and clinical allergy are not identical, results are interpreted alongside a person's history. A clinician may combine the antibody finding with symptom timing, other allergy tests, or a supervised oral food challenge to reach a conclusion.
