Method for analyzing atypical cells in urine, urine analyzer, and method for analyzing atypical cells in body fluid

A method for analyzing atypical cells in urine, comprising:

• (a) mixing urine, a diluent containing a surfactant, and a nucleic acid staining reagent to prepare a measurement specimen;
• (b) irradiating the measurement specimen with light to detect scattered light and to detect fluorescence light, with first sensitivity and second sensitivity higher than the first sensitivity, emitted from cells whose nucleic acids are stained;
• and
• (c) detecting atypical cells contained in the measurement specimen distinguishably from white blood cells based on the detected scattered light and the fluorescence light detected with the first sensitivity, and detecting bacteria contained in the measurement specimen based on the detected scattered light and the fluorescence light detected with the second sensitivity.
