Blood analyzer, method and computer program for determining existence and nonexistence of lymphoblasts in blood sample

摘要

The invention provides a blood analyzer (1) comprising a blood sample supply section, a sample preparation section (22) for preparing an assay sample by mixing the blood sample with a nucleic acid-staining fluorescent dye, a light source for irradiating the assay sample, an optical detecting section (23) for receiving fluorescence emitted from the irradiated assay sample and a controller for performing operations comprising detecting a cell group comprising lymphoblasts on the basis of the fluorescence received by the optical detecting section (23), and outputting an information on an appearance of the lymphoblasts in the blood sample, as well as a method for determining the existence and nonexistence of lymphoblasts in a blood sample.
