WBC
WBC : Abbreviation for White blood cell, White blood count. The WBC is really a nonparameter, since it simply represents the sum of the counts of granulocytes, lymphocytes, and monocytes per unit volume of whole blood. Automated counters do not distinguish bands from segs; however, it has been shown that if all other hematologic parameters are within normal limits, such a distinction is rarely important. Trying to reliably distinguish bands from segs under the microscope is fraught with reproducibility problems
