Abstract
The present invention relates to an apparatus for automatically analyzing cells in urine using flow cytometry. The present invention includes means for converting scattered-light signals indicative of individual cells in a urine specimen into corresponding pulse signals, means for converting the pulse width of each pulse signal resulting from the aforementioned conversion into cell-diameter data in accordance with known cell diameters, and means for classifying and enumerating various cells in the urine in correlation with each item of cell-diameter data resulting from the conversion.
