Abstract:
1. A blood cell analyzer, comprising: a sample aspirating section which comprises an aspiration tube for aspirating a blood sample, and which aspirates a blood sample from a sample container by using the aspiration tube; a sample preparing section configured to prepare a measurement sample from the blood sample aspirated by the sample aspirating section and a reagent; a measuring section configured to measure the measurement sample prepared by the sample preparing section; and an information processing unit comprising a processor and a memory that stores a program to be executed by the processor to: control the sample aspirating section so as to perform a first sample supplying operation in response to receiving a first measurement order to only measure a complete blood count measurement item and one or more measurement items included in a first group with respect to the blood sample, wherein the first sample supplying operation includes aspirating the blood sample by a first amount and supplying the aspirated blood sample to the sample preparing section; and control the sample aspirating section so as to perform a second sample supplying operation and a third sample supplying operation in response to receiving a second measurement order to measure a complete blood count measurement item and one or more measurement items included in a second group different from the first group with respect to the blood sample, wherein the second sample supplying operation includes aspirating the blood sample by the first amount for the complete blood count measurement item and supplying the aspirated blood sample to the sample preparing section, and the third sample supplying operation includes aspirating the blood sample by a second amount for one or more measurement items included in the second group and supplying the aspirated blood sample to the sample preparing section, wherein the complete blood count measurement item comprises measuring the amount of red blood cells, platelets, hemoglobin, and white blood cells in the aspirated blood sample, wherein the first group comprises at least one of a white blood cell classification item for classifying white blood cells into a plurality of groups, a measurement item related to reticulocytes, a measurement item related to nucleated red blood cells, a measurement item related to immature blood cells, and a measurement item related to abnormal lymphocytes; and wherein the second group comprises at least one of a measurement item relating to hematopoietic progenitor cells, and a measurement item relating to malaria parasite.
