About Onion Allergy Test | Food Allergies in Orange
Onion is a common culinary ingredient, and an allergy to it can be easy to overlook when symptoms appear alongside other foods.
IgE antibodies are part of the immune system's response to substances it identifies as threats. When a person is sensitized to onion, the body may produce specific IgE antibodies that bind to onion proteins. A blood test quantifies that antibody level to help determine whether onion is a likely trigger.
Onion belongs to the Allium genus, which also includes garlic, leeks, shallots, and chives. People with an onion allergy may react to some of these related plants because their proteins share structural similarities. The test result is interpreted alongside a person's symptom history and any other testing a clinician orders.
Results are typically reported as a numerical value with a reference range. A detectable level of specific IgE indicates sensitization, but sensitization does not always equal a clinical allergy. Only a qualified healthcare professional can combine test data with symptoms to reach a diagnosis and recommend next steps.
