About Onion Allergy Test | Food Allergies in Brea
Onion is a frequent component of many dishes, which can make avoidance difficult when a reaction is suspected.
Onion belongs to the Allium genus, a group that also includes garlic, leeks, shallots, and chives. Allergic reactions to onion are uncommon but well documented, and they can occur even when the onion is cooked, since some allergenic proteins survive heat.
The test works by drawing a blood sample and analyzing it for IgE antibodies that bind specifically to onion. The presence of these antibodies indicates that the immune system has been sensitized to onion proteins, though sensitization alone does not always produce symptoms.
Results are typically interpreted alongside a person's clinical history. A healthcare provider can explain what a positive or negative finding means in the context of symptoms, other test results, and dietary exposure.
