About Mean Platelet Volume
MPV (Mean Platelet Volume) measures the average size of platelets — larger platelets are younger, more metabolically active, and more reactive, with a greater capacity to form clots. Elevated MPV is associated with increased platelet reactivity and higher cardiovascular risk, independent of platelet count, and is seen in conditions like acute myocardial infarction, metabolic syndrome, and diabetes. Low MPV alongside low platelet count points toward bone marrow suppression rather than peripheral destruction, aiding the differential diagnosis of thrombocytopenia.
