mean platelet volume (MPV) is a measurement that describes the average size of platelet cells in the blood. It is a measurement that is usually included in the results of a typical comprehensive blood test. The importance of mean platelet volume lies in the fact that this measurement provides an indicator as to whether the bone marrow is manufacturing platelets normally.
Mean Platelet Value (MPV) 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. Since the average platelet size is larger when the body is producing increased numbers of platelets the MPV test results can be used to make inferences about platelet production in bone marrow or platelet destruction problems.
