Cal Factor x Dilution Factor
Mean of Platelet VOL histogram
Explanation
Platelets with volumes greater than
20 fL
Mean of Platelet PC histogram
Mean of Platelet PM histogram
SD of Platelet PC histogram
Raw cell count for platelets and large
platelets from 2D-platelet analysis
(PLT x MPV) ÷ 10,000
100 x (SD of Platelet VOL histogram
÷
MPV)

for platelets only
SD of Platelet PM histogram
Raw cell count for RBCs, RBC
ghosts, and RBC fragments from 2D-
platelet analysis
Number of Red Cells-2D from 2D-
platelet analysis x RBC Cal Factor x
