Hematological analyzer, method for analyzing body fluid and computer program product

摘要

A hematological analyzer for measuring blood, sets a body fluid measurement mode; receives a measurement start instruction; irradiates a measurement sample with light and obtains optical information from cells contained in the measurement sample; and classifies at least white blood cells and nucleated cells other than white blood cells contained in the measurement sample, and counts the white blood cells and nucleated cells other than white blood cells based on the optical information obtained from the cells in the measurement sample prepared from a body fluid sample and white blood cell measuring reagent when the body fluid measurement mode has been set and the measurement start instruction has been selected, is disclosed. A method for analyzing body fluid and a computer program product are also disclosed.

主权项

1. A hematological analyzer for measuring blood, comprising:
a measurement mode setting unit that sets a measurement mode selected from among a body fluid measurement mode under which white blood cells and anomalous cells other than blood cells are classified and a blood measurement mode under which white blood cells are classified into a plurality of subclasses; a measurement starting unit that receives a measurement start instruction; a sample aspirating unit that aspirates a sample comprising a body fluid sample or a blood sample; a measurement sample preparing unit comprising at least one reaction chamber in which a white blood cell measuring reagent and the sample are mixed so as to prepare a measurement sample; an optical information obtaining unit that irradiates the measurement sample with light and obtains optical information from cells contained in the measurement sample; one or more processors and one or more memories storing instructions executed by the one or more processors, the instructions comprising; controlling the measurement sample preparing unit to prepare the measurement sample and to supply the measurement sample to the optical information obtaining unit in accordance with the measurement mode set by the measurement mode setting unit; and classifying the cells contained in the measurement sample based on the optical information, and counting the classified cells, the instructions further comprising: when the body fluid measurement mode has been set by the measurement mode setting unit, in response to receiving the measurement start instruction by the measurement starting unit, controlling the measurement sample preparing unit to prepare the measurement sample from the white blood cell measuring reagent and the body fluid sample aspirated by the sample aspirating unit and to supply the measurement sample to the optical information obtaining unit, classifying the cells contained in the measurement sample as white blood cells and anomalous cells other than blood cells based on the optical information, and counting the white blood cells and the anomalous cells other than blood cells; and when the blood measurement mode has been set by the measurement mode setting unit, in response to receiving the measurement start instruction by the measurement starting unit, controlling the measurement sample preparing unit to prepare the measurement sample from the white blood cell measuring reagent and the blood sample aspirated by the sample aspirating unit and to supply the measurement sample to the optical information obtaining unit, and classifying the white blood cells contained in the measurement sample into a plurality of subclasses based on the optical information.
