Abstract
A method for the quality control of nucleated red blood cells on a hematology analyzer using a mixture of human and animal blood, particularly chicken blood and fixed human blood with nucleated red blood cells. The control material illustrated good stability over a fifty day period when stored at 4 degrees Celsius. The cell morphology showed good cell shape and the equipment had a stable nucleated red blood cell number and nucleated red blood cell per 100 white blood cells number. The method is used for quality control as for calibration for nucleated red blood cell counting or staging, on a hematology analyzer.
