Apparatus and method for analyzing cells in urine

摘要

A method and apparatus are provided for analyzing cells in urine. A constricted zone through which various cells contained in a urine specimen flow in single file is irradiated with light having a light beam width in the direction of cell flow of between 1 mu m to 20 mu m. Scattered light and fluorescent light emitted by the cells is converted into scattered-light intensity data and fluorescent light intensity data. Preferably, the individual cells have been stained with a stain such that DNA will specifically emit fluorescence. Cell diameter data and peak-count data are also generated from the detected scattered light. Cell judgement values are stored in a memory device, and the cells in the urine specimen are classified based upon the cell judgement values.
