Mean Platelet Volume – MPV
(fl)
Average volume of individual platelets derived from
the PLT histogram
Thrombocrit – PCT
(percentage, absolute)
Calculated from the PLT and MPV values
PCTpercentage = PLT x MPV x 100
PCTabsolute = PLT x MPV
White blood cell, 4 part differential:
LYM (%) : lymphocytes
MON (%) : monocytes and some
eosinophils
NEU (%) : neutrophil granulocytes
EOS(%):eosinophil granulocytes
Relative value are calculated from the optical 4 diff
scatter populations
BAS (%):basophil granulocytes
Relative value is calculated from the basofil optical
scatter populations
