Apparatus and method for differentiating erythrocytes in urine

摘要

An apparatus for differentiating erythrocytes in urine includes: a sheath flow cell for forming a urine specimen flow by surrounding a urine specimen with a sheath liquid, the urine specimen containing particles; a light application device for applying light to the urine specimen flow; a light detector for detecting a light signal emitted by each particle in the urine specimen flow; an identification device for identifying erythrocytes from the particles in the urine specimen flow in accordance with the detected light signal; a particle size distribution preparing device for preparing a particle size distribution diagram of the identified erythrocytes; a determining device for determining an origin of the erythrocytes in accordance with an erythrocyte size value at which an accumulated frequency of erythrocytes as counted from a smallest size in the particle size distribution diagram agrees with a preset value larger than half of a total accumulated frequency in the particle size distribution diagram; and an output device for outputting a determination result.
