  • Patent number: 11002746
    Abstract: Disclosed is a blood analyzer that includes: a sample preparation unit configured to mix a blood specimen and a fluorescent dye for staining nucleic acid to prepare a measurement sample; a light receiver configured to receive fluorescence and scattered light that are generated by light being applied to the measurement sample prepared by the sample preparation unit; and a controller programmed to determine whether or not infection with Plasmodium has occurred, on the basis of a value representing variation of a distribution of first particles in a range where single-ring form of red blood cells appear, the range where single-ring form of red blood cells appear being identified according to fluorescence intensities and scattered light intensities obtained by processing of signals from the light receiver.

  • Patent number: 10379120
    Abstract: 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.
