Order Onion Allergy Test | Food AllergiesAn onion allergy test measures the amount of immunoglobulin E (IgE) antibodies the immune system produces in response to onion proteins.

About Onion Allergy Test | Food Allergies in Gresham
Onion is a common culinary ingredient, yet true allergy to it is uncommon and often overshadowed by non-allergic food intolerances.
Onion belongs to the Allium genus, which also includes garlic, leek, and chives. Proteins within these plants can act as allergens, and IgE antibodies directed against them may trigger symptoms such as itching, hives, or gastrointestinal discomfort after ingestion or handling.
An onion allergy test quantifies specific IgE in a blood sample. Results are reported as a numerical value, and higher concentrations generally indicate a greater likelihood of clinical reactivity, though the test alone cannot confirm that every reaction will be severe.
Interpreting results requires context. A positive IgE finding may appear alongside other Allium sensitivities, and some individuals show antibodies without symptoms. Clinicians typically combine test data with a detailed history of reactions to reach a diagnosis.
