Automated differentials: a strategy.

A strategy for the use of the newer technology for automated leukocyte differential counting is proposed. The design of the system is felt to be cost effective, yet guarantees that patients with mild or early stages of potentially serious hematologic diseases will not be missed. A key feature of this system is a rapid visual scan of the blood film by an expert morphologist. Implementation of this system should permit significant reductions in personnel as well as reagents and other supplies.
