Patent ID: 8284384

Claim:
An apparatus for analyzing a blood sample, comprising: a chamber adapted to quiescently hold the sample; an illuminator operable to illuminate the sample along one or more fluorescent excitation wavelengths and one or more absorption wavelengths; an image dissector operable to image the sample, and produce image signals representative of fluorescent emissions from, and optical density of, first constituents and second constituents disposed within the sample, which first constituents are different from the second constituents; and an analysis device adapted to determine one or more fluorescent emission values for each of the first constituents and second constituents using the image signals, and adapted to determine one or more optical density values for each of the first constituents and second constituents using the image signals, which optical density is a function of the colorant absorbed by the constituents, and adapted to identify the first constituents and the second constituents using the determined fluorescent emission and optical density values.
