Platelets, also known as thrombocytes, are colourless cell fragments that lack nuclei and have been derived from their precursors - megakaryocytes in the bone marrow[1]. Approximately 1x1011 platelets are produced daily[2]. They are involved in the prevention of blood loss from the body through haemostasis mechanisms of blood vessel constriction, platelet plug formation and blood coagulation. Platelets have a life span of about 10 days and remain inactive in the blood unless activated when there is a rupture in blood vessels.
