GLOSSARY
WBC (White Blood
Cell) White Blood Cell count results from the CBC analysis. The WBC count is
adjusted for interfering substances when appropriate. No further correction of
WBC is required. Interfering substances include, but are not limited to NRBC,
giant platelets, platelet clumps, unlysed RBCs and RBC fragments.
This parameter is measured directly using the Coulter Principle.
WBC = n x cells/µL
Wettability The ability of any solid surface to be wetted when in contact with a liquid.

Average (EWMA) of CBC and Reticulocyte Paramters and compares them with
known target values. See XM Analysis Overview for an explanation of intended
use.
