About Onion Allergy Test | Food Allergies in Gresham
Onion allergy is an immune-mediated reaction to proteins found in onion.
When the immune system mistakenly identifies onion proteins as harmful, it produces immunoglobulin E (IgE) antibodies. These antibodies bind to mast cells and basophils, and upon subsequent exposure to onion, they trigger the release of histamine and other mediators, leading to allergy symptoms.
Symptoms of onion allergy can include itching, hives, swelling, nasal congestion, sneezing, abdominal pain, nausea, vomiting, or in severe cases, anaphylaxis. Reactions may occur after eating raw or cooked onion, and some individuals react to onion powder or other forms.
This test detects the presence of onion-specific IgE in the blood. It is used alongside a clinical history to support the diagnosis of onion allergy. A positive result indicates sensitization, but it does not alone confirm that symptoms will occur upon exposure.
