14) RDW-CV (RBC distribution width - CV)
RBC distribution width (%) calculated from the points defining 68.26% of the entire
area spreading from the peak of the RBC particle distribution curve.
15) RDW-SD (RBC distribution width - SD)
The distribution width (fL) at the height of 20% from the bottom when the peak RBC
particle distribution curve is taken as 100%.
16) PLT (Platelet) (Analysis principle: DC detection method)
Platelet count in 1 µL of whole blood
17) PDW (Platelet distribution width)*
The distribution width (fL) at the height of 20% from the bottom with the peak of
platelet particle distribution curve taken as 100%.
18) MPV (Mean platelet volume)
Mean volume of platelet (fL)
19) P-LCR (Large platelet ratio) *
Ratio (%) of large platelet volume exceeding 12 fL to the platelet volume
NOTE: • When analyzing in the pre-diluted mode, only the CBC8 parameters
are output.
• The RBC distribution width is the switchover type between RDW-SD
and RDW-CV.
* For Investigational Use Only in the United States of America.
Not a reportable parameter.
