About Onion Allergy Test | Food Allergies in Oxnard
Onion allergy testing uses a blood sample to detect sensitization to onion proteins.
The test measures allergen-specific IgE antibodies, the type of immune protein associated with immediate allergic reactions. A blood draw is performed, and the sample is analyzed in a laboratory for reactivity to onion.
Onion is a common ingredient in soups, sauces, and prepared foods, which can make it difficult to isolate as a trigger through diet alone. Testing provides objective information that can be reviewed alongside a clinical history of symptoms.
Results are reported as a quantitative or semi-quantitative value. A positive result indicates sensitization, but it does not by itself confirm that onion causes symptoms; a qualified healthcare professional interprets the result in the context of the patient's history.
