bleeding, iron deficiency anemia and
myeloproliferative syndromes. • Disseminated intravascular coagulation
• Bone marrow depression
• Autoimmune hemolytic anemia
• Severe hemorrhage

MPV

Indirect evidence of increased (bone mar-
row) megakaryocyte response. Not an accurate predictor of decreased mega-
karyocyte response.

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.
