Test Methodology

SYSMEX XN Series or XE Series. 

Clinical Utility

This assay measures the hematologic parameters of the blood. It aids in the evaluation of anemia, leukemia, reaction to inflammation and infections, peripheral blood cell characteristics, state of hydration and dehydration, polycythemia, hemolytic disease of the newborn, and ABO incompatibilities.
