Abstract: Automation of analysis of cells contained in different types of specimens collected from different organs or sites is enabled. This sample preparation method is a method for preparing a sample for analyzing cells contained in a specimen, and includes: obtaining a dispersion condition corresponding to the type of the specimen; and dispersing the cells aggregated and contained in the specimen, according to the obtained dispersion condition.

Abstract: A sample pretreatment apparatus includes: a plurality of sample pretreatment sections, each of which executes a sample pretreatment prior to a measurement; and a robotic arm including: an articulated arm member; and a hand attached to the articulated arm member. The plurality of sample pretreatment sections includes a sample dispenser that dispenses a sample in a first sample container into a second sample container. For a first measurement, the robotic arm holds the second sample container with the hand and transports the second sample container to a pretreatment group of the plurality of sample pretreatment sections, the pretreatment group including the sample dispenser. For a second measurement, the robotic arm holds the second sample container with the hand and transports the second sample container to another pretreatment group of the plurality of sample pretreatment sections, the another pretreatment group including the sample dispenser.

Abstract: The method includes a counting step of counting, among cells included in a sample, a first cell number indicating the number of cells classified into a first group based on cell size and cell nucleus size and having a DNA amount greater than a threshold value, and a second cell number indicating the number of cells classified into a second group that is different from the first group based on the cell size and cell nucleus size and having a DNA amount greater than the threshold value; and a comparing step of comparing the first cell number with the second cell number.
