Patent number: 9945783Abstract: Provided is a canceration information providing method capable of presenting the information related to canceration of the cells with high reliability. A cell in which the amount of DNA is greater than or equal to the amount of DNA of the normal cell in the S period is extracted from a cell group of V11?N/C ratio?V12 (first counting step). If the number of cells obtained in the first counting step is greater than or equal to the threshold value S1 (S107: YES), “Cancer” is set to a flag 1. A cell in which the amount of DNA is 2C is extracted from a cell group of V13?N/C ratio?V11 (second counting step). A ratio of the number of cells obtained in the second counting step and number of cells obtained in the first counting step is calculated, and “Cancer” is set to a flag 2 if the ratio is greater than or equal to a threshold value S2 (S111: YES). If one of the flags 1, 2 is “Cancer” (S113: YES), the display of retest necessary is performed.Type: GrantFiled: March 18, 2013Date of Patent: April 17, 2018Assignee: SYSMEX CORPORATIONInventors: Ryuichiro Ebi, Koki Tajima, Shigeki Abe
