Blood cell analyzer, blood cell analyzing method, and non-transitory storage medium

A blood cell analyzing method, comprising:

• a step of receiving an order of a measurement item with respect to a blood sample;
• a step of aspirating the blood sample in a sample container using an aspirating tube, and supplying the aspirated blood sample to a sample preparing section to prepare a measurement sample to be used in a measurement;
• a step of preparing the measurement sample from a reagent and the blood sample supplied to the sample preparing section;
• and
• a step of measuring the prepared measurement sample, wherein
• when a first measurement order has been received to only measure a complete blood count measurement item and one or more measurement items included in a first group in the receiving step, a first sample supplying operation is performed in the supplying step, wherein the first sample supplying operation comprises an operation of aspirating the blood sample by a first amount and an operation of supplying the aspirated blood sample to the sample preparing section;
• and
• when a second measurement order has been received to measure a complete blood count measurement item and one or more measurement items included in a second group different from the first group in the receiving step, a second sample supplying operation and a third sample supplying operation are performed in the supplying step, wherein the second sample supplying operation comprises an operation of aspirating the blood sample by the first amount for the complete blood count and an operation of supplying the aspirated blood sample to the sample preparing section, and the third sample supplying operation comprises an operation of aspirating the blood sample by a second amount for the one or more measurement items of the second group and an operation of 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.

At least one non-transitory storage medium which stores programs executable collectively by at least one processor to perform processes comprising:

• receiving an order of a measurement item with respect to a blood sample;
• and
• controlling a sample aspirating section to aspirate a blood sample in a sample container using an aspirating tube, and supplying the aspirated blood sample to a sample preparing section, wherein
• the processor controls the sample aspirating section so as to perform a first sample supplying operation when a first measurement order has been received 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 comprises an operation of aspirating the blood sample by a first amount and an operation of supplying the aspirated blood sample to the sample preparing section;
• and
• the processor controls the sample aspirating section so as to perform a second sample supplying operation and a third sample supplying operation when a second measurement order instruction has been received 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 comprises an operation of aspirating the blood sample by the first amount for the complete blood count measurement item and an operation of supplying the aspirated sample to the sample preparing section, and the third sample supplying operation comprises an operation of aspirating the blood sample by a second amount for the one or more measurement items of the second group and an operation of supplying the aspirated 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.

A blood cell analyzer with a first measurement mode, and a second measurement mode for measuring a second group of one or more measurement items in addition to a complete blood count measurement item and one or more measurement items of a first group that are measured in the first measurement mode, the 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 configured to:
• control the sample aspirating section so as to perform a first sample supplying operation in the first measurement mode, the first sample supplying operation comprises an operation of aspirating the blood sample by a first amount to only measure a complete blood count measurement item and the one or more measurement items of the first group and an operation of 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 the second measurement mode, wherein the second sample supplying operation comprises an operation of aspirating the blood sample by the first amount for the complete blood count measurement item, and an operation of supplying the aspirated blood sample to the sample preparing section, and the third sample supplying operation comprises an operation of aspirating the blood sample by a second amount for the second group of one or more measurement items and an operation of 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.
