Order Onion Allergy Test | Food AllergiesAn onion allergy screen measures the amount of immunoglobulin E (IgE) antibodies in the blood that are specific to onion proteins.

About Onion Allergy Test | Food Allergies in Lemoore
This test examines the immune system's antibody response to onion using a single blood sample.
Onion is a common culinary ingredient, and reactions to it are often attributed to non-allergic irritation such as tearing or nasal congestion. A true allergy involves the immune system producing IgE antibodies that recognize specific proteins in the food. When those antibodies bind to their target, they can prompt cells to release histamine and other mediators, which produce symptoms that may include hives, itching, swelling, stomach upset, or, in severe cases, difficulty breathing.
The onion allergy screen detects onion-specific IgE in serum. Because antibody levels reflect sensitization rather than a guaranteed clinical reaction, results are interpreted alongside a person's history and, when appropriate, additional evaluation by a qualified health professional. A negative result does not entirely rule out allergy, and a positive result does not by itself confirm that symptoms will occur on exposure.
Blood testing offers a standardized way to look for antibody sensitization without relying on the food itself. The sample is collected at a laboratory and analyzed for onion-specific IgE. Turnaround is typically one to three business days, and preparation follows the instructions provided by the laboratory performing the collection.
