Order Hazelnut (Filbert) Allergy Test | NutsA hazelnut allergy test measures the amount of specific IgE antibodies in the blood that react to hazelnut proteins. Hazelnuts, also called filberts, are tree nuts that can trigger immune responses ranging from mild oral itching to more serious reactions. This blood-based test provides objective information that helps distinguish a true hazelnut allergy from other causes of symptoms.
About Hazelnut (Filbert) Allergy Test | Nuts in Berkeley
Hazelnut allergy is an immune-mediated response to proteins found in hazelnuts and filberts.
When a person with a hazelnut allergy is exposed to hazelnut proteins, the immune system produces specific IgE antibodies that bind to mast cells and basophils. On subsequent exposure, these antibodies trigger the release of histamine and other mediators, which cause symptoms such as hives, swelling, stomach upset, or breathing difficulty.
Hazelnut is one of the tree nuts most often associated with food allergy, and reactions can occur after eating the nut, inhaling dust from processed hazelnuts, or occasionally through skin contact. Because hazelnut proteins can cross-react with certain other tree nuts and with pollen allergens, a positive test result is interpreted alongside the patient's history and other findings.
The test uses a blood sample to quantify hazelnut-specific IgE. Results are reported as a concentration or class and are used by clinicians to help confirm or rule out sensitization to hazelnut. A negative result generally makes IgE-mediated hazelnut allergy less likely, while a positive result indicates sensitization that may or may not correspond to clinical symptoms.
