1. A sample measurement device comprising:
a first measurement section configured to perform a first measurement for a blood coagulation test;
a second measurement section configured to perform a second measurement for a test different from the blood coagulation test;
a dispensing mechanism unit configured to dispense plasma from a sample container, which contains plasma, a buffy coat, and red blood cells, using a nozzle, the dispensing mechanism unit including the nozzle configured to aspirate and discharge the plasma and a drive section for lifting and lowering the nozzle, the sample measurement device; and
a controller configured to:
cause the dispensing mechanism unit to lower the nozzle to aspirate the plasma for use in the first measurement from the sample container by lowering the nozzle to a first position in the sample container;
lift the nozzle holding the aspirated plasma, discharge the plasma from the sample container into a first container for use in the blood coagulation test;
cause the dispensing mechanism unit to lower the nozzle to aspirate the plasma for use in the second measurement from the sample container by lowering the nozzle to a second position lower than the first position in the same sample container;
dispense the plasma for use in the second measurement from the sample container into a second container different from the first container, and
wherein dispensing comprises the lowering of the nozzle to aspirate the plasma for use in the first measurement from the sample container by the lowered nozzle, lifting the nozzle holding the aspirated plasma, and discharging the plasma into the first container, before dispensing plasma for use in the second measurement.
