About Onion Allergy Test | Food Allergies in Normal
The Onion Allergy Screen uses a blood sample to assess sensitization to onion proteins.
Specific IgE antibodies are produced by the immune system when it mistakenly identifies a harmless substance, such as a food protein, as a threat. This test quantifies the level of IgE antibodies directed against onion in the bloodstream.
Elevated IgE results indicate sensitization to onion, but they do not by themselves confirm a clinical allergy. A diagnosis depends on the combination of test results, reported symptoms, and a clinician's evaluation.
Blood testing is one approach among several for investigating food allergies. It offers a standardized measurement that can be tracked over time, though it cannot predict the severity of a future reaction.
