About Onion Allergy Test | Food Allergies in Merced
Onion allergy testing focuses on the immune system's response to onion proteins rather than on digestive intolerance.
An onion allergy involves IgE antibodies that recognize specific proteins in onion. When these antibodies bind to onion proteins, they can trigger the release of histamine and other chemicals from immune cells, leading to symptoms that may include itching, hives, swelling, or gastrointestinal discomfort.
A blood test for onion-specific IgE provides a laboratory measure of sensitization. The result is reported as a numerical value or class, which a healthcare provider interprets alongside a person's history of symptoms and other clinical findings.
Onion is used in many prepared foods, sauces, and seasonings, so identifying a sensitivity can be useful when evaluating reactions that occur after meals. Testing does not replace a medical evaluation, and results should be reviewed with a qualified healthcare professional.
