What this test is

This test measures specific IgE antibodies in the blood that are associated with allergic sensitivity to onion. It is typically used alongside a clinical history to help evaluate whether onion may be triggering allergic symptoms.

What it measures

  • Onion-specific IgE — Reflects the level of IgE antibodies that bind to onion proteins.
  • Total IgE — Sometimes measured to provide context for allergic tendency, though not specific to onion.

What the test involves

A healthcare professional collects a small blood sample, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test when a person reports symptoms such as hives, itching, or digestive upset after eating onion or foods containing onion. It is often part of a broader evaluation for food allergies.

Preparation

How results are reported
