Abstract
A cell analyzing method includes measuring cells that are nuclear stained, by a cytometric device, to obtain a histogram of a parameter of a fluorescence signal, where the parameter indicates an amount of DNA in a nucleus of a cell. A number of cells that are distributed in an area where the parameter of the fluorescence signal is larger than normal cells are obtained by a computer having at least one processor. The possibility of cancer is determined based on the obtained number of cells and the histogram.
Claims20
A cell analyzing method comprising:
- measuring, by a cytometric device, cells that are nuclear stained, to obtain a histogram of a parameter of fluorescence signal, the parameter indicating an amount of DNA in a nucleus of a cell;
- obtaining, by a computer comprising at least one processor, a number of cells that are distributed in an area where the parameter of the fluorescence signal is larger than normal cells;
- and
- determining possibility of cancer based on the obtained number of cells and the histogram.
A cell analyzing method comprising:
- measuring, by a cytometric device, an intensity of fluorescence emitted from each of cells that are nuclear stained to prepare a distribution of the cells according to an amount of DNA in a nucleus of a cell;
- analyzing, by a computer comprising at least one processor, the distribution of the cells to calculate a ratio of abnormal cells which have an amount of DNA greater than normal cells;
- and
- displaying the calculated ratio.
A cell analyzer comprising:
- a cytometric device which measures cells that are nuclear stained;
- a display which displays a histogram of a parameter of fluorescence signal by using a result of the measurement by the measuring portion, the parameter indicating an amount of DNA in a nucleus in a cell;
- and
- a computer comprising at least one processor configured to obtain a number of cells that are distributed in an area where the parameter of the fluorescence signal is larger than normal cells, and determine possibility of cancer based on the obtained number of cells and the histogram.
