About Onion Allergy Test | Food Allergies in Tuckahoe
Onion allergy testing is a blood-based immunoassay that quantifies IgE antibodies directed against onion allergens.
The test requires a blood sample, which is processed in a laboratory to measure the concentration of onion-specific IgE. IgE is the class of antibody most closely associated with immediate hypersensitivity reactions, and elevated levels can indicate that the immune system has been sensitized to onion proteins.
Sensitization does not always translate into clinical symptoms, so results are interpreted alongside a person's history and other findings. A qualified healthcare professional can explain what a given value means in context and whether additional evaluation is appropriate.
Onion is a common ingredient in many prepared foods, which can make avoidance challenging for individuals with a confirmed allergy. Testing can help clarify whether onion is a likely trigger and support informed decisions about dietary management.
