A hazelnut allergy test, also called a filbert allergy test, uses a blood sample to measure allergen-specific IgE antibodies against hazelnut proteins. Hazelnut is a tree nut and a common trigger of food allergy symptoms. Because hazelnut shares proteins with birch pollen, some people react to hazelnut as part of pollen-related food sensitivity. A provider may order the test after a reaction to hazelnuts or nut spreads, or as part of a broader tree nut panel. It is a screening tool and is interpreted with symptoms and history.

• Hazelnut-specific IgE Antibodies produced against hazelnut (filbert) proteins; used to assess sensitization to hazelnut.

• People who develop hives, itching, or swelling after eating hazelnuts
• Individuals with tingling or itching in the mouth after hazelnut or nut spreads
• Those with digestive upset, vomiting, or diarrhea after tree nuts
• People with eczema or skin reactions who suspect a tree nut trigger
• Anyone with a history of birch pollen allergy and reactions to hazelnut

• No fasting is required for this IgE allergy test
• The blood sample can be collected at any time of day
• Tell the provider about medications such as antihistamines
• No special diet is needed beforehand

Results are reported as an IgE level or class for hazelnut. An elevated value may indicate sensitization, but sensitization does not always mean a person will react when eating hazelnuts. A low or undetectable level makes a true allergy less likely, though it does not completely rule one out. Hazelnut proteins can cross-react with birch pollen, so a provider may consider pollen-related food sensitivity. Discuss results with a healthcare provider before removing tree nuts from your diet.
