ABSTRACT:
An apparatus and method for directly determining the hemoglobin content (CH) of individual sphered red blood cells and for directly determining the width of the cell hemoglobin distribution of a red blood cell sample. Such apparatus and method monitors the light reflected by individual sphered cells as they are made to pass through an optical flow cell while being irradiated by a suitable source of radiation.
