Abstract:
1. A blood analyzer, comprising: a sample preparing part comprising a first chamber for preparing a first measurement sample comprising blood, a hemolyzing reagent, and a staining reagent and a second chamber for preparing a second measurement sample comprising blood and a diluent; a first detection unit comprising a flow cell in which the first measurement sample flows, a light source for irradiating the first measurement sample flowing in the flow cell, a PIN photodiode for detecting a side scattered light from the first measurement sample irradiated by the light source, and an avalanche photodiode for detecting a side fluorescence light from the first measurement sample irradiated by the light source; a second detection unit comprising a second flow cell in which the second measurement sample flows and electrodes that detect changes of direct current resistance therebetween caused by the second measurement sample flowing therebetween; a signal processing part configured for processing a side scattered light signal from the PIN photodiode, a side fluorescent light signal from the avalanche photodiode and a third detection signal from the electrodes, the signal processing part comprising:
