URINE SAMPLE ANALYSIS DEVICE AND URINE SAMPLE ANALYSIS METHOD

摘要

A sample analysis device (100) prepares a first measurement sample from a diluted solution (19u) having no hemolytic action on a urine sample and from a staining solution (18u) that stains membrane; and obtains a fluorescence signal by supplying the first measurement sample to a flow cell (51), irradiating laser light on the sample, and receiving fluorescent light emitted from the first measurement sample. In addition, the sample analysis device (100) prepares a second measurement sample from a diluted solution (19b) having a hemolytic action on the urine sample and from a staining solution (18b) that stains nuclei; and obtains a fluorescence signal by supplying the second measurement sample to the flow cell (51), irradiating laser light on the sample, and receiving fluorescent light emitted from the second measurement sample. Particles not having nucleic acid including red blood cells are detected on the basis of information about the fluorescence signal obtained from the first measurement sample and cells having nucleic acid including white blood cells are detected on the basis of information about the fluorescence signal obtained from the second measurement sample.
