Order Onion Allergy Test | Food AllergiesAn onion allergy screen is a blood test that looks for immunoglobulin E (IgE) antibodies directed at onion.

About Onion Allergy Test | Food Allergies in Fallbrook
Onion allergy is uncommon but recognized, and it can be difficult to separate from other reactions to foods.
Onion is a member of the Allium genus, a group that also includes garlic, leeks, chives, and shallots. Because these plants share some proteins, a person who reacts to one allium may sometimes react to others, though cross-reactivity is not guaranteed.
Reported symptoms of onion allergy have included skin reactions such as hives or itching, digestive upset, and in rare cases more severe responses. Some people also experience irritation of the eyes or airways when cutting or cooking onions, which is typically a non-allergic irritant effect rather than an immune reaction.
This test measures onion-specific IgE in a blood sample. A result is interpreted alongside a person's history and other findings, since the presence of antibodies alone does not always correspond to clinical symptoms, and a negative result does not rule out every form of food-related reaction.
