About Onion Allergy Test | Food Allergies in Gresham
This test uses a blood sample to detect IgE antibodies specific to onion.
When the immune system identifies a food protein as a threat, it can produce IgE antibodies tailored to that protein. Those antibodies bind to immune cells, and subsequent exposure to the same protein may prompt the release of histamine and other mediators that cause allergy symptoms.
An onion allergy test quantifies the amount of onion-specific IgE circulating in the blood. The result is reported as a numerical value that a clinician interprets alongside a person's symptom history, because a detectable antibody level alone does not always correspond to a clinical reaction.
Onion is used widely in cooking, and reactions to it are uncommon but documented. Testing can be useful when symptoms such as hives, itching, or gastrointestinal discomfort occur after eating onion or foods that contain it. Results should be reviewed with a qualified healthcare professional who can determine their significance.
