Blood based Plasmodium infection analyzer

A blood analyzer including a specimen preparation unit, a flow cell, a light source unit, light receivers, and a processing unit. The processing unit is configured to identify and count lymphocytes in the first measurement specimen by using first scattered light information based on the first scattered light and second scattered light information based on the second scattered light, and configured to identify and count blood cells having thereon the predetermined surface antigen in the first measurement specimen by using first fluorescence information based on the first fluorescence.

Blood analyzer and blood analysis method

Disclosed is a blood analyzing method including: a step of preparing a measurement sample from blood, a fluorescent dye represented by the following formula 1, and a diluent, a concentration of the fluorescent dye in the measurement sample being greater than or equal to 0.15 &#x3bc;M and smaller than or equal to 1.0 &#x3bc;M; a step of acquiring fluorescence information obtained by irradiating the measurement sample with light; and a step of detecting a red blood cell infected with a malaria parasite in the blood based on the fluorescence information. 

Blood analyzing method as well as stain solution and blood analyzer used for the same

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.
