The hematocrit (Ht or HCT, British English spelling haematocrit), also known as packed cell volume (PCV) or erythrocyte volume fraction (EVF), is the volume percentage (%) of red blood cells in blood. It is normally 45% for men and 40% for women. It is considered an integral part of a person's complete blood count results, along with hemoglobin concentration, white blood cell count, and platelet count.
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.
