Patent ID: 8333926

Claim:
An apparatus, for analyzing particles in urine, comprising: a measurement specimen preparing section configured to prepare a measurement specimen by combining a urine sample and a stain reagent; an optical detecting section comprising: a light source configured to emit a light that illuminates the prepared measurement specimen, a forward-scattered light receiving element configured to detect forward-scattered light emitted from the specimen, and further configured to output a forward-scattered light output signal, a side-scattered light receiving element configured to detect side-scattered light emitted from the specimen, and further configured to output a side-scattered light output signal, and a fluorescence receiving element configured to detect fluorescence emitted from the specimen, and further configured to output a fluorescence output signal; and a computer, comprising a central processing unit (CPU) and a memory storing a computer executable program, configured to measure leukocytes in urine based on: a detected forward-scattered light amount derived from the forward-scattered light output signal, a detected side-scattered light amount derived from the site-scattered light output signal, and a detected fluorescence amount derived from the fluorescence output signal, wherein, when executed by the CPU, the computer executable program causes the computer to generate: a first analysis result identifying an appearance region for leukocytes and epithelial cells in urine, based at least in part on an analysis of the detected forward-scattered light amount and the detected fluorescence amount, and a second analysis result identifying an appearance region of leukocytes and epithelial cells in urine, based at least in part on an analysis of the detected forward-scattered light amount and the detected side-scattered light amount; and wherein, the computer executable program further causes the computer to generate an indication that discriminates leukocytes from epithelial cells based on the first analysis result and the second analysis result.
