摘要： A method and apparatus for determining hemoglobin concentration is provided. A method aspect includes the steps of: a) depositing an unlysed, substantially undiluted blood sample into an analysis chamber adapted to quiescently hold the sample for analysis; b) imaging the sample in a region of the analysis chamber where the height of the chamber is no more than about twenty microns (20μ) or no less than about two microns (2μ), to produce image signals representative of the optical density of the imaged region; c) determining a sample representative optical density value using the image signals representative of the optical density of the imaged region; and d) determining the hemoglobin concentration of the sample using the sample representative optical density value.

摘要： A method and apparatus for determining a cell volume of a red blood cell is provided. The method includes the steps of: a) depositing a sample into an analysis chamber, the chamber defined by an first panel interior surface, a second panel interior surface, and a known or determinable height, which height is such that at least one red blood cell subject to a sphering agent assumes a partially compressed spherical shape in contact with the interior surfaces; b) imaging the at least one partially compressed spherical red blood cell contacting the interior surfaces, and producing image signals; c) determining a radius of the partially compressed spherical red blood cell from the image signals; and d) determining a volume of the imaged red blood cell using the determined radius.
