Abstract: Today's automated hematology analyzers capable of performing a full CBC and a differential leukocyte count (DLC) on whole blood, particularly in a closed tube system, using cytochemistry or impedance-based flow cytometry technology coupled with laser light scattering, conductivity and/or differential cell lysis, are here to stay. Their need and popularity among at least the large, cost and quality-conscious clinical laboratories have been growing for the past few years and will continue to do so in the years ahead. The efficiency and reliability of several of these analyzers in performing complete CBCD (CBC and DLC) and in flagging significant abnormalities have been tested and found acceptable with the need to review a stained blood smear or perform a manual DLC to confirm or obtain additional information on selected cases.
