Abstract
Provided are a sample analyzer and a sample analysis method. The sample analyzer includes: a sampling apparatus configured to collect a blood sample; a sample preparation apparatus configured to mix the blood sample with a hemolytic agent and a dye to prepare a test sample liquid; an optical detection apparatus configured to detect side-scattered light signals and fluorescence signals generated by particles in the test sample liquid; and a processor configured to: generate a scatter diagram based on at least the side-scattered light signals and the fluorescence signals, and obtain a predetermined feature region, wherein an intensity of side-scattered light corresponding to a central position of the predetermined feature region is greater than an intensity of side-scattered light corresponding to a central position of a region containing neutrophil granulocyte population; and obtain a blast cell parameter based on the predetermined feature region.
