BLOOD CELL ANALYZER AND BLOOD CELL ANALYZING METHOD
First Claim
1. A blood cell analyzer comprising:
- a flow cell configured to flow a measurement specimen containing blood cells;
a first light source configured to emit light having a first wavelength on the measurement specimen;
a second light source configured to emit light having a second wavelength different from the first wavelength on the measurement specimen;
a first light receiving portion configured to receive first scattered light generated by irradiating the blood cells in the measurement specimen with light from the first light source;
a second light receiving portion configured to receive second scattered light generated by irradiating the blood cells in the measurement specimen with light from the second light source; and
a control section configured to classify at least white blood cells from the blood cells contained in the measurement specimen, based on a detection signal output from the first light receiving portion and a detection signal output from the second light receiving portion.

17. A blood cell analyzing method comprising:
-
flowing a measurement specimen containing blood cells through a flow cell; detecting first scattered light obtained by irradiating the blood cells passing through the flow cell with light having a first wavelength to acquire a first detection signal; detecting a second scattered light obtained by irradiating the blood cells passing through the flow cell with light having a second wavelength to acquire a second detection signal; and classifying at least white blood cells from the blood cells contained in the measurement specimen, based on the first detection signal and the second detection signal.

18. A blood cell analyzing method comprising:
-
mixing a specimen containing blood cells and a fluorescence labeled antibody that specifically reacts with a cell surface antigen, and preparing a measurement specimen without performing a process of removing red blood cells; flowing the prepared measurement specimen through a flow cell; detecting first scattered light obtained by irradiating the blood cells passing through the flow cell with light having a first wavelength to acquire a first detection signal; detecting second scattered light obtained by irradiating the blood cells passing through the flow cell with light having a second wavelength to acquire a second detection signal; detecting fluorescence obtained by irradiating the blood cells passing through the flow cell with light having a predetermined wavelength to acquire a third detection signal; and classifying white blood cells contained in the measurement specimen for a cell surface antigen, based on the first detection signal, the second detection signal, and the third detection signal. - View Dependent Claims (19, 20)
