BLOOD ANALYZER, BLOOD ANALYSIS METHOD AND HEMOLYTIC AGENT

摘要

This blood analyzer includes a sample preparation portion preparing a measurement sample free from a labeling substance from a blood sample and a hemolytic agent free from a labeling substance, a light information generation portion generating fluorescent information and at least two types of scattered light information from the measurement sample and a control portion performing a first classification of white blood cells in the measurement sample into at least four groups of monocytes, neutrophils, eosinophils and others on the basis of the fluorescent information and the two types of scattered light information.

主权项

1. A blood analysis method comprising:
preparing a measurement sample from a blood sample and a hemolytic agent without a fluorescent dye; flowing the measurement sample in a flow cell; irradiating the measurement sample running in the flow cell with a beam of light to induce intrinsic fluorescence and scattered light from each of white blood cells in the measurement sample; detecting the intrinsic fluorescence and at least two types of scattered light from each of white blood cells in the measurement sample; and classifying the white blood cells in the measurement sample into at least four groups of (a) monocytes, (b) neutrophils, (c) lymphocytes and basophils, and (d) eosinophils on the basis of the intrinsic fluorescence and the two types of scattered light.
