About this test

This blood test checks for IgE sensitization to peppertree pollen, a fall tree pollen. Peppertree is common in Florida and California. Sensitization is not the same as allergy, so the result is read with your history. There is nothing to do ahead of your visit.

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 peppertree pollen, often when sneezing, congestion, or itchy eyes follow the fall season, or before seeing an allergist.

What does this test measure?

The result shows your level of IgE to peppertree pollen, one piece of information an allergist or other healthcare provider reads alongside when and where your symptoms happen.

Peppertree pollen-specific IgE
This marker measures IgE antibodies to peppertree pollen, a fall 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 peppertree pollen may play a part in seasonal symptoms.

What your results tell you

Results come back as an IgE level in kU/L, compared with the lab’s reference range. Above the range shows sensitization, not necessarily allergy.

Questions

It does not tell you whether you will react to peppertree pollen, or how strongly. IgE shows sensitization, and many sensitized people have no symptoms. A negative result does not clear an allergy either.

Decisions about pollen exposure or care belong with an allergist or other healthcare provider who knows your history.

Peppertree pollen is a fall tree pollen, common in Florida and California. Pollen seasons can shift with weather and location, so timing varies from year to year.

When your symptoms happen is one clue an allergist or other healthcare provider uses alongside a result like this. A positive result shows sensitization, not that this pollen is the cause of your symptoms.

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 to peppertree pollen 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.
