Biologic fluid analysis system with sample motion

摘要

An apparatus for and method of analyzing a biologic fluid sample is provided. The method includes the steps of: a) providing a sample cartridge having at least one channel for fluid sample passage; b) providing an analysis device having imaging hardware, a programmable analyzer, and a sample motion system, which sample motion system includes a bidirectional fluid actuator operable to selectively move a bolus of sample axially within the channel, and to cycle the bolus back and forth within the channel; and c) cycling the bolus of sample disposed within the channel at a predetermined frequency until constituents within the sample are substantially uniformly distributed, using the bidirectional fluid actuator.
