Patent ID: 7563620

Claim:
A method for correcting for cell aggregates in a cell suspension from patients comprising the steps of: obtaining samples of cells from the cell suspension; scanning by laser cytometry the samples; storing data about the samples; identifying in the data cell aggregates in the samples from the samples that have been scanned with an APT function defined by X =log(normalized nuclear area×normalized nuclear perimeter), where normalized nuclear area cell=cell nuclear area/mean nuclear area of G 1 cells with a lowest ploidy level in the sample, and normalized nuclear perimeter=cell nuclear perimeter/mean nuclear perimeter of G 1 cells with the lowest ploidy level in the sample; and Y= 1/(normalized texture value), where normalized texture value=cell texture value/mean cell texture value of G 1 cells with the lowest ploidy level in the sample according to a heuristic: for X<0.75, Y<0.5X, and, for X>=0.75, all Y.
