About Onion Allergy Test | Food Allergies in Ocoee
Onion allergy is uncommon but can occur. The body may treat certain onion proteins as harmful and produce IgE antibodies against them.
When someone with an onion allergy eats onion, IgE antibodies bind to the proteins and trigger the release of chemicals such as histamine. This can lead to symptoms that may include hives, itching, swelling, stomach upset, or, in severe cases, difficulty breathing.
An onion allergy test detects the presence of IgE antibodies directed at onion. A blood sample is drawn and analyzed in a laboratory. Results are reported as a numerical value or a class, which helps a clinician assess whether onion-specific IgE is present.
A positive result indicates sensitization to onion, but it does not by itself confirm that symptoms will always occur. Diagnosis considers the test result alongside a person's history and, when appropriate, other evaluation. A negative result generally makes an IgE-mediated onion allergy less likely.
