About Onion Allergy Test | Food Allergies in Poway
Onion allergy testing evaluates the immune system's response to onion allergens through a blood sample.
IgE antibodies are produced by the immune system in response to substances it mistakenly identifies as harmful. When a person is sensitized to onion, these antibodies can bind to onion proteins and trigger the release of chemicals such as histamine, which cause allergy symptoms. A blood test detects the level of onion-specific IgE in the bloodstream.
Symptoms of an onion allergy may include itching, hives, swelling of the lips or tongue, digestive discomfort, or in severe cases, difficulty breathing. Because reactions can vary and some symptoms overlap with other conditions, testing provides objective information that helps a healthcare provider distinguish a true allergy from other causes.
The test requires a blood draw, which is typically performed in a clinical setting. Results are reported as a numerical value or a class score indicating the concentration of onion-specific IgE. These results must be interpreted by a qualified healthcare professional alongside the patient's medical history and reported symptoms.
