What it measures
- Onion-specific IgE — Antibodies made by the immune system that can recognize onion proteins.
- Total IgE — A general measure of allergic antibody levels in the blood.
- Allergen component profile — A closer look at which specific onion proteins may trigger a reaction.
Preparation
No fasting or special preparation is usually needed. Tell your clinician about any medicines you take, because some antihistamines can affect allergy test results.

How long does it take to get results?
Results are usually available within 1 to 3 business days.
Can this test tell me how severe a reaction will be?
No. The test helps show whether you are sensitized to onions, but it cannot predict how mild or severe a future reaction might be.
