    摘要： A method and apparatus for analyzing white blood cells (WBCs) within a whole blood sample quiescently residing within a chamber is provided. The chamber is defined by at least one transparent panel, and the whole blood sample includes at least one colorant operable to differentially identify at least one WBC type from another WBC type within the sample. The method includes the steps of: a) creating at least one image of the sample quiescently residing within the chamber; b) identifying portions of the sample image, with each portion representing a single WBC; c) compressing the sample image portions using a first compression algorithm; and d) one of compressing a remainder of the sample image not included in the portions using a second compression algorithm, or discarding the remainder.

    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.
