Order Hazel Nut Tree Allergy Test | Tree PollenThe Hazel Nut Tree Allergy Test measures specific IgE antibodies in the blood to hazel tree pollen and hazelnut allergens.

About Hazel Nut Tree Allergy Test | Tree Pollen in Durham
This test evaluates immune system reactivity to hazel tree pollen and hazelnut proteins using a blood sample.
Hazel trees release lightweight pollen in late winter and early spring, and their pollen is a common trigger of seasonal allergic rhinitis in many regions. Because hazelnut proteins can share structural similarities with pollen allergens, some individuals with hazel pollen allergy also experience oral itching or mild swelling after eating hazelnuts, a pattern known as pollen-food syndrome.
The test detects allergen-specific IgE antibodies, the immune proteins associated with immediate hypersensitivity reactions. A blood draw is performed, and the sample is analyzed in a laboratory to determine whether IgE antibodies bind to hazel pollen or hazelnut extracts. Results are reported as a quantitative or semi-quantitative value, which is interpreted alongside the patient's clinical history.
A positive result indicates sensitization, meaning the immune system has produced IgE antibodies against hazel allergens, but it does not by itself confirm that symptoms will occur on exposure. Conversely, a negative result makes IgE-mediated allergy less likely but does not entirely exclude it. Healthcare providers use the result in combination with symptom timing, exposure history, and other findings to guide diagnosis and management.
