ABSTRACT:
Apparatus and method are provided for determining mean corpuscular volume of cells in a sample passing through a conductivity cell. A coincidence corrected red blood cell count is generated by conventional means, and a signal indicative of hematocrit level is provided. A digital representation of the corrected red blood cell count is loaded into a register connected to comparator means. A digital output generated in response to the hematocrit level indicated by the hematocrit signal is utilized as a clock pulse train. The clock pulse train has a total length indicative of the hematocrit level, or a multiple thereof. The count indicated by the clock pulse train is compared by the comparator means, which acts as a divider, to the red blood cell count. The output of the comparator means comprises a digital number which is indicative of the mean corpuscular volume of a sample.
