About Onion Allergy Test | Food Allergies in Algonquin
Onion allergy is uncommon, but it can occur as part of a broader pattern of reactions to foods in the Allium genus.
The test works by exposing a blood sample to onion allergen and measuring any IgE that binds to it. A positive result indicates sensitization, meaning the immune system has produced onion-specific IgE. Sensitization and clinical allergy are not identical, so results are interpreted alongside symptoms and medical history.
Reactions to onion are often reported as oral itching or tingling, and in some cases hives, eczema flares, or gastrointestinal upset. More severe reactions are possible but rare. Because onion is frequently cooked into mixed dishes, identifying it as a trigger can require careful attention to ingredient labels and food preparation.
Onion belongs to the Allium family, which also includes garlic, leek, chives, and shallot. Some individuals react to several of these foods, while others tolerate them. Testing can help clarify which specific allergens are relevant, but it does not by itself predict the severity of a future reaction.
