Web30 de mar. de 2024 · Platelets are blood cells that play a major role in blood clotting. The clot acts like a mesh to stop the bleeding. Platelets travel where there is an injury to form a mesh that plug the injury. The MPV is the measurement of the average size of platelets found in blood and is typically measured in femtoliter (10 -15 liter).
