An onion allergy screen is a blood test that measures immunoglobulin E (IgE) antibodies directed at onion proteins. IgE is the antibody class most closely associated with immediate allergic reactions, so its presence in the blood can help clarify whether a person's symptoms are consistent with a true onion allergy rather than another cause.

About Onion Allergy Test | Food Allergies in Independence

This test uses a blood sample to detect IgE antibodies that bind to onion.

Allergic reactions to onion are uncommon but well documented. When the immune system mistakenly identifies onion proteins as harmful, it can produce IgE antibodies specific to those proteins. Those antibodies attach to mast cells and basophils, and on later exposure they trigger the release of histamine and other mediators that produce symptoms such as itching, hives, swelling, or gastrointestinal discomfort.

An onion allergy screen quantifies the level of onion-specific IgE in the bloodstream. A detectable result indicates that the immune system has been sensitized to onion proteins, which may support a diagnosis when considered alongside a person's history and physical findings. Sensitization does not always equate to clinical allergy, so results are interpreted in context rather than in isolation.

Onion can appear in the diet in many forms, including cooked, raw, powdered, and as part of spice blends, which can make avoidance and symptom tracking challenging. A blood-based IgE test offers a standardized way to assess sensitization without relying on skin testing, and it can be useful when skin testing is not practical or when a clinician wants an additional data point.
