A blood analyzing method comprises irradiating light on a measurement sample prepared using fluorescent dye so as to produce a difference in fluorescence intensity between reticulocytes and mature red blood cells in a blood sample, detecting scattered light and fluorescent light given off from blood cells in the measurement sample, and obtaining fluorescence data related to the fluorescent light and scattered light data related to the scattered light for each blood cell, determining the possibility of the presence ofparasites in the blood sample based on the distribution conditions of blood cells in the reticulocyte distribution range based on the scattered light data and the fluorescent light data.

Blood analyzing method and blood analyzer

A blood analyzer comprises a sample preparing part configured to prepare a measurement sample from a blood sample, an staining dye and diluent, a detecting part configured to detect the fluorescent light intensity and the scattered light intensity, an output part, and an analyzing part configured to identify the population including red blood cells infected by ring-form malaria parasite based on the fluorescent light intensity and the scattered light intensity, and output to the output part the information relating to infection ofbased on the scattered light distribution of particles associated with the identified population that includes red blood cells infected by the ring-form malaria parasite.
