What it measures
- Japanese cedar pollen-specific IgE — The main marker; it shows whether your immune system makes antibodies against this pollen.
- Total IgE — A general measure of allergy-related antibodies in your blood, sometimes included for context.
- Other pollen-specific IgE — Sometimes tested alongside to compare reactions to different pollens.
Who it is for
A primary care clinician, allergist, or immunologist typically orders this test. It may also be ordered for people who live in or travel to regions where Japanese cedar pollen is common and who have seasonal allergy symptoms.
Preparation
No fasting or special preparation is required for this blood test. You can eat, drink, and take your usual medications unless your clinician gives other instructions.
Results and what they mean
Results are reported as a level of specific IgE, often as a number or a class range, and are interpreted alongside your symptoms and history. A clinician, not the lab report alone, determines what the result means for you. This information is general and not medical advice; discuss your results with a qualified healthcare professional.

Frequently asked questions
Do I need to stop my allergy medication before this test?
Usually not. Allergy medications do not affect blood IgE levels the way they can affect skin tests, but check with your clinician before making any changes.
How long does it take to get results?
Results are typically available within 1 to 3 business days after your blood sample is collected.
Can this test tell me if I will have symptoms?
It shows sensitivity, but sensitivity does not always mean you will have symptoms. Your clinician will interpret the result with your symptom history.
Is this test painful?
It is a standard blood draw, so you may feel a brief pinch when the needle goes in. The sample is usually taken from a vein in your arm.
