A walnut tree IgE blood test detects antibodies against walnut tree pollen. Walnut trees release airborne pollen that can contribute to seasonal allergy symptoms in sensitized people. This test focuses on pollen rather than the nut itself and is a screening tool rather than a diagnosis on its own. It may be ordered when symptoms follow a spring pollen pattern or when a broader tree pollen panel is being reviewed.

• Walnut tree pollen-specific IgE Antibodies produced against walnut tree pollen proteins; used to assess sensitization to the tree's pollen.

• Spring-season sneezing, nasal itching, or congestion around walnut bloom
• Itchy or watery eyes that flare with tree pollen
• Cough or wheezing associated with a pollen season
• Suspected walnut tree pollen allergy being evaluated
• Testing within a larger tree pollen panel

• No fasting is required for this IgE antibody test.
• Tell the collector about allergy medicines you use, as some may affect testing.
• No dietary changes or special timing are needed.

The test reports walnut tree pollen-specific IgE. A low or undetectable level suggests no meaningful sensitization, while an elevated level may indicate the immune system recognizes walnut pollen and can be associated with seasonal symptoms. This test measures pollen sensitization and is distinct from a walnut food allergy test. Discuss your results with a healthcare provider for accurate interpretation.
