1. A blood analyzer comprising:
a first sample preparation unit configured to prepare, from a blood sample, a first measurement sample for measuring a red blood cell infected with malaria;
a second sample preparation unit configured to prepare, from the blood sample, a second measurement sample for measuring intrinsic fluorescence of a red blood cell, the first sample preparation unit being physically separated from the second sample preparation unit;
a suction unit configured to suction the blood sample from a sample container that stores the blood sample through a suction tube, the suction unit being configured to move the suction tube to the first sample preparation unit and the second sample preparation unit respectively, the suction unit being configured to supply the blood sample to the first sample preparation unit and the second sample preparation unit respectively;
a light source unit configured to apply light to the first measurement sample and the second measurement sample;
a detection unit configured to detect fluorescence and scattered light generated from the first measurement sample to which light has been applied, and detect intrinsic fluorescence generated from the second measurement sample to which light has been applied; and
an information processing unit configured to generate information about malaria infection based on fluorescence and scattered light detected from the first measurement sample, and generate information about iron-deficiency anemia based on intrinsic fluorescence detected from the second measurement sample.
