Quick answer
This test detects IgE antibodies that react to hackberry tree pollen in a blood sample. It is used when seasonal sneezing, nasal congestion, or itchy eyes coincide with hackberry pollination. A healthcare provider interprets the result together with the full timing and pattern of your symptoms.
What this test measures
Hackberry trees release lightweight pollen that can travel long distances on the wind and trigger allergic rhinitis in sensitive people. Because the pollen season overlaps with other trees, it can be hard to identify the source from symptoms alone. The test measures specific IgE antibodies formed against hackberry pollen proteins.
The sample is a serum specimen collected by a standard blood draw, and testing can be performed year-round. Laboratories report hackberry-specific IgE, total IgE, and a reactivity class. Panels may also include related tree pollens and cross-reactive proteins such as profilin to help explain the overall pattern.
People order this test when spring or early summer symptoms are severe, when over-the-counter measures are not enough, or when allergy shots or avoidance planning are being considered. The report is one element of a full evaluation performed by a qualified healthcare provider.

No fasting is required, and the blood sample can be collected at any time of year. Timing relative to pollen season does not change the sample requirements. Follow the laboratory instructions.
Understanding your results
Results are generally available within one to three business days. A positive finding indicates sensitization to hackberry pollen, which a healthcare provider interprets together with symptom timing and other allergy results.

Hackberry typically pollinates in spring, though timing varies by climate and weather patterns.
Do I need to be tested during pollen season?
No. The antibody response persists, and the sample can be collected at any time.
Can tree pollen allergies cause asthma symptoms?
Pollen can worsen airway symptoms in some people, and a healthcare provider can evaluate whether asthma is involved.
Will this test show which tree is responsible?
It measures hackberry specifically, while additional tree markers in the panel help map the wider picture.
What sample is needed?
A small venous blood sample collected at a laboratory is all that is required.
