About Onion Allergy Test | Food Allergies in Gilroy
Onion is a common culinary ingredient, and reactions to it can arise through several mechanisms that are not always allergic in nature.
An IgE-mediated allergy to onion occurs when the immune system identifies onion proteins as harmful and releases IgE antibodies against them. On subsequent exposure, these antibodies can trigger the release of histamine and other mediators from immune cells, producing symptoms that may include itching, hives, swelling, or gastrointestinal discomfort.
Not every adverse reaction to onion is a true allergy. Some people experience irritation of the skin or mucous membranes from the pungent compounds released when onion is cut, while others may have non-allergic food intolerance or reactions related to other conditions. An IgE blood test helps distinguish sensitization from these other causes.
Because onion is often consumed alongside other ingredients, identifying it as the trigger can be difficult from symptoms alone. Testing for specific IgE to onion provides objective information that a clinician can interpret alongside the history and, when appropriate, other evaluation.
