IgE is the class of antibody most closely associated with immediate allergic reactions, so its presence can help clarify whether onion is a trigger for symptoms.
About Onion Allergy Test | Food Allergies in Gresham
This test uses a blood sample to detect an allergic reaction to onion.
The body's immune system sometimes identifies a harmless food protein as a threat and produces IgE antibodies against it. When onion is eaten again, those antibodies can prompt cells to release histamine and other chemicals, which may lead to itching, hives, swelling, or digestive upset.
A blood test for onion-specific IgE looks for those antibodies directly. It does not require eating onion during the visit, which makes it a practical option when a reaction has been severe or when skin testing is not suitable.
Results are reported as a level of specific IgE. A detectable level suggests sensitization to onion, but sensitization alone does not always mean symptoms will occur. The result is best interpreted alongside a person's history and other clinical findings.
