Abstract
A hematology analyzer provides a pulse signal in which the number of pulses manifests the number of blood cells in a sample volume of blood and the magnitude of each pulse manifests the size of each such blood cell. The analyzer also provides an analog voltage manifesting the hemoglobin content of the blood sample. Means responsive to the pulse signal provide an analog voltage manifesting the hematocrit of the blood sample and an analog voltage manifesting the number of cells. An analog-to-digital converter is switchably responsive to the analog hemoglobin, hematocrit and cell count signals to provide required ratios reflecting the mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration of the blood sample.
