METHOD AND APPARATUS FOR MEASURING MEAN CELL VOLUME OF RED BLOOD CELLS

摘要

METHOD AND APPARATUS FOR MEASURING MEAN CELL VOLUME OF RED BLOOD CELLS An apparatus and method are provided for producing signals representative of the mean cell volume of red blood cells in a blood specimen. The apparatus includes means (310) for generating signals representative of the area of the cells and means (318) for measuring the optical density of the individual cells and for generating signals representative of the hemoglobin content or mass of the cells. The central pallor is measured for cells having central pallors and means (264) generate a signal representative of the central pallor of these cells. The representative area signals, hemoglobin signals and central pallor signals are sent to a means (403, 415) which generates an output (430) representative of the mean cell volume of the cells.
