Order Onion Allergy Test | Food AllergiesAn onion allergy test measures the presence of immunoglobulin E (IgE) antibodies directed at onion proteins in a blood sample. IgE is the antibody class most closely associated with immediate allergic reactions, so this test is used to help evaluate whether a person's symptoms may be linked to an immune response to onion.
About Onion Allergy Test | Food Allergies in Pasadena
This test is a specific IgE blood assay for onion, intended to support the assessment of suspected food allergy.
The test detects IgE antibodies that bind to onion proteins. When a person is sensitized to onion, their immune system produces these antibodies, which can be measured in serum. The result is reported as a quantitative or semi-quantitative value, often alongside a reference range or class score.
Onion is a common ingredient in many prepared foods, and reactions to it can be difficult to distinguish from reactions to other foods eaten at the same time. A specific IgE test for onion helps isolate the response to this particular food, which can be useful when symptoms occur after meals containing onion.
As with other specific IgE tests, the result must be interpreted in the context of a person's clinical history. A positive result indicates sensitization, not necessarily a clinical allergy, and a negative result does not entirely rule out a reaction. Healthcare providers use the test alongside symptom patterns and other findings to reach a conclusion.
