8,000 units of blood are needed every day to meet hospital demand in the UK. Blood comes in four main types – O, A, B and AB. Group O is the most common which means it is in high demand. Blood can also be subdivided into its main components – red cells, white cells, platelets and plasma. Unfortunately red cells only have a shelf-life of 35 days, while platelets shelf life is even less, only five days.
