Walnut Tree Allergy Test is a laboratory test you can order directly. A walnut tree allergy test checks your blood for antibodies that may react to proteins from walnut tree pollen. It is usually ordered when a person has seasonal allergy symptoms such as sneezing, itchy eyes, or nasal congestion, especially in spring when walnut trees release pollen. It can help a clinician see whether walnut pollen may be contributing to your symptoms.

A walnut tree allergy test checks your blood for antibodies that may react to proteins from walnut tree pollen. It is usually ordered when a person has seasonal allergy symptoms such as sneezing, itchy eyes, or nasal congestion, especially in spring when walnut trees release pollen. It can help a clinician see whether walnut pollen may be contributing to your symptoms.
What it measures
- Walnut pollen-specific IgE — The main marker; IgE is an antibody linked to allergy reactions.
- Total IgE — A general measure of allergy-related antibody in the blood, sometimes included for context.
- Other tree pollen-specific IgE — May be checked alongside walnut to see if related pollens also trigger reactions.
- Cross-reactive allergen markers — Proteins that can overlap with certain foods or other pollens, which may explain related symptoms.
Who it is for
A primary care clinician or allergist typically orders this test after reviewing your symptom pattern and timing. It may be used when skin testing is not possible or when more information is needed.
Preparation
No fasting or special preparation is usually required. Tell your clinician about any allergy medications you take, because some can affect allergy testing.
Results and what they mean
Results are reported as a level or class for walnut pollen-specific IgE, along with any other markers tested. A clinician interprets these values together with your symptoms and history; a positive result alone does not confirm an allergy. This is general information, not medical advice.

Frequently asked questions
Does this test hurt?
It uses a standard blood draw, so you may feel a brief pinch when the needle goes in.
How soon will I get results?
Most results are ready in 1 to 3 business days, though timing can vary by lab.
Can this test tell me if I am allergic to walnuts I eat?
No. It checks pollen allergy antibodies, which are different from food allergy testing.
What if my result is positive?
A positive result means antibodies were found, but your clinician will decide what it means based on your symptoms.
