Hazelnut (Filbert) Allergy Test in Tennessee

The hazelnut (filbert) allergy test is a blood test that checks for an allergic response to hazelnut proteins. It is often ordered when a person has had symptoms like hives, itching, or breathing trouble after eating hazelnuts, or when a clinician needs to confirm or rule out a hazelnut allergy.

What it measures

Hazelnut-specific IgE antibodies — The main marker; it measures antibodies your immune system may make against hazelnut proteins.
Total IgE — A general allergy antibody level that can help put the specific result in context.
Other tree nut-specific IgE — Sometimes tested together to see if reactions may involve other nuts.

Who it is for

A clinician such as an allergist, primary care doctor, or pediatrician typically orders this test after a suspected reaction or when evaluating ongoing allergy symptoms.

Preparation

No fasting or special preparation is needed. The blood sample can be collected at any time of day.

Results and what they mean

Results are usually reported as a number for hazelnut-specific IgE, often with a reference range or class score. A clinician interprets the result along with your symptoms and history; a positive test alone does not always mean a true allergy. This is general information, not medical advice.
