About Onion Allergy Test | Food Allergies in Algonquin
Understanding onion allergy and IgE testing
Onion is a common culinary ingredient, and allergic reactions to it are relatively uncommon but can occur. When the immune system mistakenly identifies onion proteins as harmful, it can release IgE antibodies and histamine, leading to symptoms that may appear within minutes to hours after exposure.
This test uses a blood sample to measure specific IgE antibodies directed against onion. Unlike skin prick testing, a blood test does not require direct exposure to the allergen on the skin, making it a useful option for certain individuals. Results are typically reported as a numerical value or class, which a healthcare provider interprets alongside clinical history.
A positive result indicates sensitization to onion, meaning the immune system has produced IgE antibodies. However, sensitization does not always equate to a clinical allergy. Diagnosis should be made by a qualified healthcare professional who considers symptoms, medical history, and test findings together.
