ABSTRACT:
An analyzer for analyzing urine material components includes: a sheath flow cell for forming a sample stream containing the urine material components; a light source for illuminating the sample stream; a section for detecting optical information from the illuminated material component particles; and an analyzing section for analyzing the material components; the analyzing section including section for extracting parameters from the detected optical information, a section for generating first and second distribution diagrams on the basis of the extracted parameters, an inputting section for inputting a domain in the first distribution diagrams, a domain determining section for clustering the material component particles according to the kind of material component to define a domain for each of the material components in at least one of the first and second distribution diagrams, and a section for computing the number of data points of material component particles simultaneously belonging to a domain in the first distribution diagram inputted from the inputting section and a domain in the second distribution diagram defined by the domain determining section.
