A 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 test provides objective information that helps distinguish a true hazelnut sensitization from other causes of symptoms.

About Hazelnut (Filbert) Allergy Test | Nuts in Pasadena

Hazelnut allergy testing is used when a person reports symptoms after eating hazelnuts or foods containing them, or when a clinician needs to confirm or rule out sensitization to this tree nut.

The test detects allergen-specific IgE antibodies in a blood sample. When the immune system identifies hazelnut proteins as harmful, it can produce these antibodies, which bind to mast cells and trigger the release of histamine and other chemicals during exposure.

Results are reported as a quantitative value, often in kilounits of antibody per liter (kU/L), along with a reference range. A detectable level indicates sensitization, but sensitization alone does not always mean a clinical allergy will occur; the result is interpreted alongside symptoms, history, and other findings.

Hazelnut proteins can cross-react with pollen allergens, particularly birch pollen, which may cause oral allergy syndrome in some individuals. Because of this, a positive result should be evaluated in the context of the person's specific reactions and exposure history.
