About Onion Allergy Test | Food Allergies in Pacifica
This test examines the immune system's antibody response to onion.
IgE antibodies are the class of immunoglobulins most closely associated with immediate allergic reactions. When a blood sample is analyzed for onion-specific IgE, the result reflects whether the immune system has produced antibodies that recognize onion proteins.
A positive result indicates sensitization, meaning IgE antibodies to onion were detected. Sensitization does not automatically confirm that eating onion will cause symptoms; the clinical picture and the person's history remain essential to interpretation.
Onion is a common ingredient in many cuisines, so identifying a true allergy can require careful review of both test results and reactions to foods. This screen provides one piece of that assessment and is typically ordered alongside a broader allergy evaluation.
