PDWsd
Platelet Distribution Width
fl
Calculated from RDWcv and the distribution width
of the platelet histogram at 20% of peak
PDWsd = PDWcv x (P
2
+ P
1
) / 0.56
PDWcv
Platelet Distribution Width
CV
%
Derived from same histogram as above
PDWcv = PDW
CAL
x 0.56 x (P
2
- P
1
) / (P
2
+ P
1
)
Factor of 0.56 converts measurement at 60% of
peak to 20% of peak
