Estimating Hematocrit from Hematologic Parameters
The hematocrit is the ratio of the red blood volume to the volume of whole blood. A close relationship exists between hemoglobin and hematocrit which can be used if only one value is available or for quality control. In automated hematologic analyzers, the hematocrit is not directly measured. Rather, it is calculated from the red blood cell count and MCV, which are measured.
