Abstract
In a hematology analyzer, peaks of pulses indicative of red blood cells in a sample during a count are detected. Peak detecting means produce a gate signal connected to gate means which couple a portion of each pulse in the time vicinity of its peak to integration means. The level accumulated in the integration means is indicative of total cell volume, and hence indicative of hematocrit for a known sample volume.
