ABSTRACT:
The present invention relates to a method and apparatus for analyzing a blood or other biological fluid sample in a quiescent state, whereby particulate constituents of biological samples that contain sparse populations of interesting cellular species can be enumerated and inspected using an optical scanning instrument. Specifically, this invention relates to a method and apparatus for obtaining increased cellular or particulate concentrations within the use of said optical scanning method.
