摘要：
A method and apparatus for determining the hematocrit of a blood sample disposed within an analysis chamber, the method comprising the steps of: a) imaging at least a portion of the sample that contains one or more red blood cells contacting the interior surfaces of the chamber 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 that are in contact the interior surfaces, 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.
