摘要： A method and apparatus for determining hemoglobin concentration is provided. A method aspect includes the steps of: a) depositing an unlyzed, 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.
