Figure 9-4-3: RBC/PLT Analysis Flow in Pre-diluted Mode
(1) Blood sample that was diluted beforehand to 1:26 dilution using CELLPACK. This
sample is aspirated from the sample probe into the sample rotor valve.
(2) 2.08 µL of diluted blood measured by the sample rotor valve is transferred in 1.99792
mL of diluent to the RBC/PLT transducer chamber, and is made into 1:25000 dilution
sample.
(3) Of the sample in the RBC/PLT transducer chamber, 250 µL is aspirated through the
aperture. At this time, RBC and PLT are calculated by the DC detection method. At
the same time, HCT (hematocrit value) is calculated by RBC pulse height detection
method.
