Order Onion Allergy Test | Food AllergiesAn onion allergy test measures the amount of immunoglobulin E (IgE) antibodies in the blood that are specific to onion. IgE is the class of antibody the immune system produces when it identifies a substance as a threat. In a true allergy, that response can trigger symptoms such as hives, itching, swelling, or digestive upset after onion is eaten or handled. A blood test offers an objective way to look for sensitization when the cause of symptoms is unclear.
About Onion Allergy Test | Food Allergies in Burke
Onion allergy testing is a focused IgE blood test that looks for antibodies directed at onion proteins.
The test requires a blood sample, which is drawn and then analyzed in a laboratory for onion-specific IgE. Results are reported as a numerical level that reflects how much of that antibody is present. A higher level generally indicates a greater likelihood of sensitization, though the number alone does not predict how severe a reaction will be.
Onion belongs to the Allium genus, along with garlic, leek, chives, and shallot. Proteins shared across these plants can sometimes cause reactions that overlap, so a clinician may consider results alongside a person's history and other tests. Cooking can change some food proteins, but it does not reliably remove the risk for everyone who is allergic.
This test is used to help evaluate suspected food allergy. It does not diagnose every kind of adverse reaction to onion, such as intolerance or irritant contact reactions, which do not involve IgE. A qualified health professional interprets the result together with symptoms, timing, and exposure history to reach a conclusion.
