MPV
Mean Platelet Volume
Indirect evidence of increased (bone mar-
row) megakaryocyte response.
Not an accurate predictor of decreased mega-
karyocyte response.
PCT
Platelet Hematocrit
Volume of platelets expressed as a per-
centage of whole blood (used as a
research tool).
Volume of platelets expressed as a percent-
age of whole blood (used as a research tool).
PDW
Platelet Distribution
Width
Increased measure of platelet anisocyto-
sis (platelet size variation) indicative of
active platelet release.
No known clinical significance.
