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

About Onion Allergy Test | Food Allergies in Fallbrook
The onion allergy screen is a targeted blood test for detecting sensitization to onion.
The test uses a blood sample to measure specific IgE antibodies directed against onion allergens. IgE is the class of antibody most closely associated with immediate allergic reactions, so its presence can indicate that the immune system has recognized onion proteins as a threat.
Sensitization does not always equal clinical allergy. A positive result shows that antibodies are present, but a healthcare provider interprets that finding alongside symptoms, timing of exposure, and medical history to determine whether a true allergy exists.
Onion is used widely in cooking, and reactions may be attributed to it when another ingredient or a non-allergic sensitivity is responsible. Testing for onion-specific IgE can help clarify the picture and guide appropriate next steps.
