Abstract: The present invention provides a method for determining a success or failure of a measurement of a target particle contained in a measurement sample. The method includes: detecting the target particle and other particle other than the target particle in the measurement sample; and determining the success or failure of the measurement of the target particle based on at least a detection result of the other particle.

Abstract: A method of determining a quality of a cell separation, according to an aspect, includes: separating, by running a specimen containing a first particle and a second particle in a flow path, the specimen to a first specimen containing the first particle and a second specimen containing the second particle, based on a difference in magnitude of a force exerted on each particle contained in the specimen; measuring first information on an amount of the first specimen and second information on an amount of the second specimen; and determining a quality of the separating based on the first information and the second information.

Abstract: A cell detection method and a cell detection system capable of performing target cell detection satisfactorily without interference and reducing the time required for detection of target cells are provided. The cell detection method includes a separation step of step S1 to obtain a sample containing target cells by removing at least a part of the non-target cells from a biological sample including target cells and non-target cells based on a difference in forces acting on target cells and non-target cells; a concentration step of step S3 of obtaining a measurement sample having a target cell concentration increased from the sample containing target cells; a detection of step S4 of detecting target cells by subjecting the measurement sample to an imaging flow cytometer.
