What this test is
This is a blood test that looks for immunoglobulin E antibodies directed against mesquite pollen. The presence of these antibodies suggests your immune system may react to mesquite, though it does not by itself confirm a clinical allergy. It is typically used alongside your symptom history and other allergy testing.
What it measures
- Mesquite-specific IgE — Reflects the level of allergic antibody directed against mesquite pollen.
What the test involves
A healthcare professional collects a small blood sample, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test when you report seasonal allergy symptoms such as sneezing, runny nose, itchy eyes, or wheezing that could be linked to mesquite trees. It is often part of a broader evaluation for tree pollen allergies.
