About Hazelnut (Filbert) Allergy Test | Nuts in Norco
Hazelnut allergy testing is a blood-based assessment of sensitization to hazelnut proteins.
The test detects immunoglobulin E (IgE) antibodies that bind to hazelnut allergens. IgE is the antibody class most closely associated with immediate allergic reactions, so its presence can support a diagnosis when considered alongside a person's history and symptoms.
Hazelnuts are the fruit of the hazel tree and are known as filberts in some regions. Reactions to hazelnut can range from mild oral itching to more serious symptoms such as hives, vomiting, or breathing difficulty. Because tree nut allergies can be severe, testing is typically interpreted by a clinician rather than used alone.
A blood sample is collected and analyzed in a laboratory, with results generally available within a few business days. A positive result indicates sensitization, not necessarily a clinical allergy, and a negative result does not entirely rule out a reaction. Follow the lab's instructions before the draw.
