About Onion Allergy Test | Food Allergies in Carson
Onion allergy testing is a blood-based assessment that looks for immunoglobulin E (IgE) antibodies directed against onion.
The test uses a blood sample to measure the presence and level of IgE antibodies specific to onion. IgE is the class of antibody typically associated with immediate allergic reactions, such as hives, itching, or gastrointestinal symptoms after eating a food.
Because the test is performed on a blood sample, it does not require exposure to the food during the test itself. Results are reported as a quantitative value that indicates whether sensitization to onion is detected.
A positive result suggests that the immune system has produced IgE antibodies to onion, but it does not by itself confirm a clinical allergy. Diagnosis should be interpreted by a healthcare provider alongside symptoms, medical history, and other findings.
