The result helps distinguish a true allergic sensitization from other causes of symptoms after eating nuts.
About Hazelnut (Filbert) Allergy Test | Nuts in Dana Point
Hazelnut allergy testing is a blood-based IgE assay that quantifies antibody binding to hazelnut proteins.
The test detects immunoglobulin E (IgE) directed against hazelnut (filbert) proteins in a blood sample. IgE is the antibody class most closely associated with immediate allergic reactions, and its presence at elevated levels suggests sensitization to hazelnut.
Hazelnut allergy can cause symptoms ranging from oral itching and hives to more severe reactions involving breathing or circulation. Because hazelnut is a tree nut, reactions may occur alongside sensitivities to other tree nuts such as birch pollen-related foods, though cross-reactivity patterns vary between individuals.
Results are reported as a quantitative IgE level and are interpreted alongside a person's clinical history. A positive result indicates sensitization, not necessarily a clinical allergy, while a negative result makes IgE-mediated hazelnut allergy less likely.
