Order Onion Allergy Test | Food AllergiesAn onion allergy screen measures the amount of immunoglobulin E, or IgE, that the immune system produces in response to onion proteins.

About Onion Allergy Test | Food Allergies in Cypress
Onion is a culinary staple that appears in countless prepared foods, which can make an allergy to it difficult to isolate through diet alone.
Onion belongs to the Allium genus, a group that also includes garlic, leeks, shallots, and chives. Because these plants share similar proteins, a person who reacts to onion may also react to related alliums, though cross-reactivity is not guaranteed.
Symptoms of an onion allergy can include itching or tingling around the mouth, hives, swelling, stomach upset, or in more serious cases, difficulty breathing. These reactions typically occur soon after eating the food, and they differ from the digestive discomfort some people experience when eating large amounts of raw onion.
The test itself requires only a blood draw. A laboratory then analyzes the sample for onion-specific IgE antibodies and reports the result, which a healthcare provider interprets alongside a person's history and other findings.
