Order Onion Allergy Test | Food AllergiesAn onion allergy test measures the level of immunoglobulin E (IgE) antibodies in the blood that are specific to onion. IgE is the antibody class most closely associated with immediate allergic reactions, and a blood test can help identify sensitization to onion proteins. This test is typically used when a person reports symptoms after eating onion or onion-containing foods, or when a clinician wants to evaluate a suspected food allergy.
About Onion Allergy Test | Food Allergies in Galt
Onion allergy is uncommon but can occur, and it is distinct from onion intolerance, which does not involve the immune system in the same way.
An IgE-mediated reaction to onion can produce symptoms such as hives, itching, swelling, stomach upset, or in rare cases more severe breathing difficulty. Because onion is often a hidden ingredient in sauces, soups, and processed foods, identifying the trigger can be challenging without testing.
The onion allergy test uses a blood sample, so it does not require exposing the person to onion directly. The laboratory measures the concentration of onion-specific IgE antibodies, and results are usually reported as a numeric value with a reference range. A higher value may indicate a greater likelihood of clinical allergy, but results are interpreted alongside the person's history and other findings.
This test is not a standalone diagnosis. Some people have detectable IgE antibodies without symptoms, and some with symptoms may have low or undetectable levels. A clinician uses the result together with symptom patterns, other allergy tests, and possibly a supervised oral food challenge to reach a conclusion.
