Hematology analyzers.

An overview of current hospital hematology analyzers has been presented. The technology involved is extraordinarily sophisticated and has provided us with interesting new and potentially useful parameters. Even the instrument evaluation process is becoming increasingly complex, but new standards are being developed that provide guidance for users. As the forces of technology and cost-containment converge, pressures arise to alter our thinking about traditional laboratory testing. Recent interest has been particularly focused on the differential count. The hematology laboratory is vastly changed from that of 25 years ago, and it's almost impossible to speculate on what it will be like a quarter century from now.
