About this test

Eucalyptus pollen is a winter to spring tree pollen, and this test measures IgE antibodies to it in your blood. Eucalyptus is common in California. A positive result shows sensitization, which does not by itself mean allergy. No fasting or other prep is needed.

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

Who should take this test?

This test is for adults whose sneezing, congestion, or itchy eyes seem to line up with the winter to spring season and who want to check IgE to eucalyptus pollen.

What does this test measure?

Your result shows whether you are sensitized to eucalyptus pollen, which a healthcare provider reads alongside when your symptoms happen and where you live.

Eucalyptus pollen-specific IgE (t18)
IgE is the antibody involved in allergic reactions. This marker is the amount of IgE in your blood that recognizes eucalyptus 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 eucalyptus pollen, a winter to spring tree pollen.

No. Sensitization means your body has made IgE to eucalyptus pollen. An allergy means that exposure causes symptoms. Many people are sensitized without having symptoms, so a positive result alone does not mean you are allergic.

A negative result does not clear an allergy either. An allergist or other healthcare provider reads your result with what happens when you are exposed.

Eucalyptus pollen is a winter to spring tree pollen, common in California. 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.

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 eucalyptus 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.
