Patent ID: 7892841

Claim:
An apparatus for measuring a hematological sample, comprising: a sample treatment part for preparing a measurement sample by giving damage to a cell membrane of erythrocyte and mature leukocyte contained in the hematological sample, constricting the damaged erythrocyte, and staining the damaged mature leukocyte with a fluorescent dye for staining nucleic acid; an obtainer for obtaining first scattered light information generated by irradiating the measurement sample with light, second scattered light information based on scattered light having a different angle from that of first scattered light, and fluorescent information; a first classifier for specifying a first cell group containing myeloblast based on the first scattered light information and the second scattered light information; a second classifier for specifying a second cell group containing myeloblast based on the first scattered light information and the fluorescent information; and a calculator for calculating cells that belong to both of the first cell group and the second cell group as myeloblast.
