Platelet Facts What are platelets? Blood is made up of four main components: red cells, white cells, platelets and plasma. Platelets help your blood to clot by forming a temporary plug in the wound that helps stop the bleeding. Why should I donate platelets? A continuous supply of fresh platelets is essential to meet the needs of patients in area hospitals. Unlike whole blood, the shelf life of a unit of platelets is only five days, so platelet donors are needed on a consistent basis in order to keep a full supply.
