About Onion Allergy Test | Food Allergies in Hackensack
Onion allergy is uncommon but possible, and it is often confused with other reactions to the vegetable.
True onion allergy involves the immune system recognizing specific proteins in onion as harmful and releasing IgE antibodies against them. When onion is eaten or sometimes handled, those antibodies can prompt cells to release histamine and other chemicals, producing symptoms such as hives, itching, swelling, stomach upset, or in severe cases difficulty breathing.
Not every unpleasant reaction to onion is an allergy. Some people experience irritation of the mouth or digestive tract, or they react to compounds such as fructans or sulfur-containing substances, without any immune involvement. An IgE blood test helps distinguish an antibody-driven allergy from these other sensitivities.
The test itself requires only a blood sample, which is analyzed in a laboratory for onion-specific IgE. Results are reported as a numerical level that a clinician interprets alongside your symptom history, because a positive result alone does not always mean you will react, and a negative result does not entirely rule out every form of sensitivity.
