About Onion Allergy Test | Food Allergies in Estero
Onion is a common culinary ingredient, and reactions to it are reported less often than reactions to other foods, which can make the cause of symptoms difficult to identify without testing.
Onion belongs to the Allium genus, a group that also includes garlic, leeks, and chives. People who react to onion may sometimes react to these related plants because their proteins share structural similarities.
An IgE antibody test for onion uses a blood sample rather than a skin prick. The laboratory adds onion allergen to the sample and measures any specific IgE that binds to it, producing a quantitative or semi-quantitative result.
A positive result indicates that IgE antibodies to onion are present. It does not, by itself, establish that onion is the cause of a particular symptom, so results are interpreted alongside a person's history and other clinical findings.
