About this test

This panel measures IgE antibodies to five tree pollens the lab groups for its Region 4, which it describes as the Great Lakes region: box elder maple, cottonwood, elm, hickory and pecan, and walnut. Check that this region fits where you live. A positive result shows sensitization, not necessarily an allergy.

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

Who should take this test?

For adults in the Great Lakes region whose sneezing, congestion, or itchy eyes follow the spring tree pollen season, who want to check several tree pollens at once.

What does this test measure?

Your results show which of these tree pollens, if any, your blood has IgE to. An allergist reads them with the timing of your symptoms and where you live.

Cottonwood pollen-specific IgE (t14)
IgE is the antibody involved in allergic reactions. This marker is the amount of IgE in your blood that recognizes cottonwood pollen, reported in kU/L. A level above the lab’s reference range means sensitization, not necessarily allergy.
Why it’s measured: To see whether you are sensitized to cottonwood pollen, a spring tree pollen.
Elm pollen-specific IgE (t8)
Specific IgE is an antibody the immune system can make against one allergen. This marker measures IgE that recognizes elm pollen, an 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 elm pollen when symptoms follow the early spring season.
Hickory and pecan pollen-specific IgE (t22)
This marker measures IgE antibodies to hickory and pecan pollen, a spring tree pollen. A level above the lab’s reference range shows the immune system is sensitized to it. Many sensitized people have no symptoms, so the result is read with your history.
Why it’s measured: Helps a healthcare provider see whether hickory and pecan pollen may play a part in seasonal symptoms.
Box elder maple pollen-specific IgE (t1)
This marker measures IgE antibodies to box elder maple pollen, a spring tree pollen. A level above the lab’s reference range shows the immune system is sensitized to it. Many sensitized people have no symptoms, so the result is read with your history.
Why it’s measured: Helps a healthcare provider see whether box elder maple pollen may play a part in seasonal symptoms.
Walnut tree pollen-specific IgE (t10)
This marker measures IgE antibodies to walnut tree pollen, a spring tree pollen. A level above the lab’s reference range shows the immune system is sensitized to it. Many sensitized people have no symptoms, so the result is read with your history.
Why it’s measured: Helps a healthcare provider see whether walnut tree pollen may play a part in seasonal symptoms.

What your results tell you

Each allergen is reported as an IgE level in kU/L and compared with the lab’s reference range. A level above the range shows sensitization.

  • Your number next to the lab’s reference range
  • Explained in plain language
  • A licensed clinician reviews your order and, if appropriate, orders the test.
  • A lab report you can download and share

An allergist or other healthcare provider reads each result with the timing of your symptoms and decides on any next steps.

The lab’s Region 4 tree panel includes 5 tree pollens:

  • box elder maple
  • cottonwood
  • elm
  • hickory and pecan
  • walnut

Each pollen is reported on its own, so you can see which, if any, show sensitization.

Region 4 is the lab’s name for a set of tree pollens grouped for the Great Lakes region. People elsewhere can be sensitized to these trees too, but other panels or single tests may fit another region better.

The licensed clinician in your state who reviews your request, or an allergist, can help you decide which tests fit.

Not on its own. A positive result means your blood has IgE to that allergen, which is called sensitization. Many sensitized people have no symptoms.

An allergist reads each result with your symptoms and when they happen. A negative result does not clear an allergy, and allergens outside this panel are not checked.

Both look for IgE sensitization. A skin test checks how your skin responds to a small amount of an allergen, while this test measures IgE in a blood sample. In many cases the two are considered comparable.

A blood test may be preferred in some situations, such as a widespread skin condition or recent use of medicines that affect skin tests. Don’t stop or change any medicine without talking with your healthcare provider.

Lab tests are informational and don’t diagnose conditions on their own. Available to adults 18 and older; test availability varies by lab location. A licensed clinician reviews your order and, if appropriate, orders the test. All testing is performed at CLIA-certified laboratories. Not for emergencies: if you think you may be having a medical emergency, call 911.
