Cell analysis method, cell analyzer and sample screening method

摘要

Disclosed is a cell analysis method comprising: extracting target cells from a population of cells derived from an epithelial tissue on the basis of N/C ratio representing a relative size of a nucleus to a cytoplasm; classifying the target cells into at least a first group and a second group by difference of amount of DNA; and evaluating a pathology of the epithelial tissue by comparing a ratio of numbers of cells between the first and second groups with a threshold; wherein the threshold varies according to a proportion of the target cells in the population.
