Order Onion Allergy Test | Food AllergiesAn onion allergy test measures the immune system's response to onion proteins. It is used when a person reports symptoms after eating onion or foods that contain it. The test relies on a blood sample and looks for specific IgE antibodies.
About Onion Allergy Test | Food Allergies in Algonquin
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.
