What is this test?

This test measures allergen-specific IgE antibodies in your blood for a panel of 10 foods. IgE is an immune-system protein that can respond to substances in food.

Why might I need this test?

It may be used when you have symptoms such as hives, swelling, wheezing, vomiting, or abdominal discomfort after eating. Your clinician may also use it to investigate a suspected food allergy.

How is the test performed?

A blood sample is collected and tested in a laboratory using an immunoassay. The report identifies the foods for which IgE antibodies were detected and provides a measured result for each food.

How do I prepare for the test?

Fasting is usually not required. Tell your clinician about any food allergies, recent reactions, and medicines you take, especially antihistamines, because these may affect interpretation; do not stop prescribed medicines without advice.

Reference range

Adult: 10-40 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.

Frequently asked questions

Does a positive result mean I am allergic to that food?
Not always. It shows that IgE antibodies were detected, which can be consistent with sensitization or allergy, but your clinician must interpret it alongside your symptoms, medical history, and sometimes other testing.
Can I eat a food because its result is negative?
A negative result lowers the likelihood of IgE-mediated allergy, but it does not rule out every type of food reaction. If you have had a serious reaction, do not reintroduce the food without medical guidance.
Which foods are included in this panel?
The panel includes 10 foods, but their exact identities are not specified by the abbreviated test name. The laboratory report should list the individual foods and results.
