Abstract
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.
