摘要
A method and apparatus for determining the hematocrit of a blood sample disposed within an analysis chamber, the method including the steps of: a) imaging at least a portion of the sample that contains one or more red blood cells and one or more areas void of red blood cells; b) determining a representative optical density value for a plurality of image units optically aligned with portions of the red blood cells, and assigning an optical density first boundary value to those image units; c) determining a representative optical density value of a plurality of image units optically aligned with the one or more regions of the sample devoid of red blood cells, and assigning a second optical density boundary value to those image units; and d) determining the hematocrit of the sample.
