Cell analysis apparatus and cell analysis method

A cell analyzing method implemented by a computer of a cell analyzer, the method comprising:

• detecting events associated with interrogation of cells and outputting a profile signal unique to a respective event, wherein the profile signal is representative of DNA amount of a nucleus of a respective cell;
• quantizing a profile signal of a respective detected event into a profile value which is derived by integrating the profile signal;
• and
• determining a relative number of events having profile values higher than a threshold value to thereby determine a relative number of cells having DNA amount greater than a threshold DNA amount.

A cell analyzer comprising:

• a measuring portion which measures cells that are nuclear stained;
• a displaying portion which displays a histogram of a pulse area of fluorescence signal by using a result of the measurement by the measuring portion;
• and
• a determining unit which obtains a number of cells that are distributed in an area where the pulse area of fluorescence signal is larger than normal cells, and which determines possibility of cancer based on the number of cells and the histogram.

A cell analyzing method comprising:

• measuring cells that are nuclear stained, to obtain a histogram of a pulse area of fluorescence signal;
• detecting a peak of normal cells from data of the histogram;
• obtaining a number of cells that are distributed in an area where the pulse area of fluorescence signal is larger than the peak of the normal cells;
• and
• determining possibility of cancer based on the obtained number of cells and the histogram.
