Abstract:
1. A cell analyzer comprising: a detecting section comprising an optical device that detects information of each cell from a measurement specimen containing cells harvested from an epithelial tissue including parabasal cells, wherein the epithelial tissue includes surface layer cells, intermediate layer cells, and the parabasal cells, where the intermediate layer cells are between the surface layer cells and the parabasal cells, and a controller comprising a CPU and a memory device programmed to: acquire a feature parameter of each cell based on the detected information, wherein the feature parameter includes a first parameter related to a size of a cell, and a second parameter related to a size of a cell nucleus, and; determine appropriateness of the cell harvesting of the parabasal cells based on the feature parameter, wherein the controller sorts the parabasal cells and cells in the surface layer cells and the intermediate layer cells based on the first parameter and the ratio of the second parameter with respect to the first parameter, and determines the appropriateness of the cell harvesting of parabasal cells based on the sorting result; and determine canceration of the parabasal cells based on the feature parameter, wherein the determination of appropriateness of the cell harvesting is performed independently from the determination of canceration.
