Order Onion Allergy Test | Food AllergiesAn onion allergy test measures the presence of immunoglobulin E (IgE) antibodies specific to onion proteins in a blood sample. IgE is the class of antibody the immune system produces when it mistakenly identifies a harmless substance as a threat. Detecting onion-specific IgE can help clarify whether a person's symptoms are consistent with an allergic response to onion.
About Onion Allergy Test | Food Allergies in Bothell
Onion allergy is uncommon but recognized, and it differs from food intolerance or irritation.
An allergic reaction to onion involves the immune system rather than the digestive system alone. When sensitized individuals encounter onion proteins, IgE antibodies bind to them and trigger the release of mediators such as histamine from mast cells. This process can produce symptoms that may include hives, itching, swelling, nasal congestion, or, in severe cases, breathing difficulty.
Onion belongs to the Allium genus, which also includes garlic, leeks, shallots, and chives. Some people react to more than one member of this group because the proteins involved can be similar. A clinician may therefore consider testing for related Allium foods alongside onion when evaluating a suspected allergy.
Diagnosis is not based on a single test result. A blood test for onion-specific IgE is interpreted together with a person's history, symptom pattern, and sometimes other testing such as skin prick tests or supervised oral food challenges. Results can support or argue against an allergy but do not by themselves confirm or exclude it.
