Mean platelet volume (MPV) is a machine-calculated measurement of the average size of platelets found in blood and is typically included in blood tests as part of the CBC. Abnormally low MPV values correlate with thrombocytopenia when it is due to impaired production as in aplastic anemia. MPV stands for mean platelet volume. Platelets are small blood cells that are essential for blood clotting, the process that helps you stop bleeding after an injury. An MPV blood test measures the average size of your platelets. The test can help diagnose bleeding disorders and diseases of the bone marrow. MPV results, along with platelet counts and other tests, can provide a more complete picture of the health of your blood. A low MPV can indicate exposure to certain drugs that are harmful to cells. It may also indicate marrow hypoplasia, a disorder that causes a decrease in blood cell production.

Also known as: MPV Automated Blood, MPV Test, Mean Platelet Volume.
