Abstract: Disclosed is a blood analyzer including a specimen preparation unit that prepares a measurement specimen by mixing a hemolytic agent that hemolyzes red blood cells, a staining dye that dyes nucleic acids, and a blood specimen; a detector that detects intensity of side scattered light and intensity of fluorescence generated with application of light from the measurement specimen prepared by the specimen preparation unit; and an analysis unit that discriminates white blood cells from giant platelets based on the intensity of side scattered light and the intensity of fluorescence detected by the detector, and counts the white blood cells.

Abstract: A measurement method, a measurement device, and a measurement program for acquiring information related to lipid particles contained in a measurement sample prepared without using a fluorescent dye are provided. The problem is resolved by the measurement method for measuring the number of particles in a measurement sample prepared without using a fluorescent dye, the method including obtaining information related to lipid particles contained in the measurement sample based on a plurality of characteristic values regarding light scattering in each particle obtained by a flow cytometer from the individual particles contained in the measurement sample.

Abstract: Disclosed is a method for displaying a result of analysis performed on a specimen containing formed components. The method includes: obtaining, from each of the formed components, measurement values of at least three parameters; displaying a screen including a three-dimensional distribution chart in which the three parameters are used as axes and the formed components are represented by dots; and hiding specific dots on the three-dimensional distribution chart or changing a display format of the specific dots, according to an operation performed by a user.
