About Onion Allergy Test | Food Allergies in Fallbrook
The Onion Allergy Screen measures specific IgE antibodies against onion in a blood sample.
IgE antibodies are part of the immune system's response to substances it treats as threats. When a person is sensitized to onion, their immune system may produce IgE that binds to onion proteins. A blood test can detect those antibodies and report the level present.
This test is typically ordered when someone reports symptoms after eating onion or foods that contain onion, such as itching, hives, swelling, stomach upset, or breathing changes. Because onion is often mixed into prepared foods, identifying it as a trigger can be difficult without testing.
Results are reported as a numeric value that reflects the amount of onion-specific IgE in the sample. A higher value suggests sensitization, but it does not by itself confirm that eating onion will cause symptoms. Sensitization and clinical allergy are related but not identical, so results are best interpreted alongside a person's history and other findings.
