About this test

Hazel pollen, a late winter to early spring tree pollen, is the allergen this blood test checks your IgE against. It is a pollen test, not a test for hazelnut as a food. Sensitization is not the same as allergy, so the result is read with your history. No fasting is needed.

For adults 18 and older. Test availability varies by lab location.

Who should take this test?

For adults who want to check for sensitization to hazel pollen, often when sneezing, congestion, or itchy eyes follow the late winter to early spring season, or before seeing an allergist.

What does this test measure?

The result shows whether you have IgE to hazel pollen. With the timing of your symptoms, it can help a healthcare provider see whether this pollen may play a part.

Hazel pollen-specific IgE
Specific IgE is an antibody the immune system can make against one allergen. This marker measures IgE that recognizes hazel pollen, a late winter to early spring tree pollen. A level above the lab’s reference range shows sensitization, read with the timing of your symptoms.
Why it’s measured: Checks for IgE sensitization to hazel pollen when symptoms follow the late winter to early spring season.

Questions

Not on its own. A positive result means your immune system has made IgE to hazel pollen, which is called sensitization. Many people who are sensitized have no symptoms when they are exposed.

A diagnosis of allergy is made by a healthcare provider who looks at your symptoms and history along with results like this one. A negative result also does not by itself mean you are not allergic.

No. This test measures IgE to hazel pollen, which is usually checked for seasonal symptoms. Hazelnut as a food has its own test, so this result does not tell you whether you will react to eating hazelnuts.

Decisions about eating any food belong with an allergist, who reads pollen and food results together with your history.

Hazel pollen is a late winter to early spring tree pollen. Pollen seasons can shift with weather and location.

When your symptoms happen is one clue an allergist uses alongside a result like this. A positive result shows sensitization, not that this pollen causes your symptoms.
