1 One out of every 10 people entering a hospital needs blood. 2  Just one pint of donated blood can help save as many as three people's lives. 3  The average adult has 10 pints of blood in his or her body.
During a whole blood donation we aim to take just under a pint (about 470mls) of blood, which works out at no more than 13 per cent of your blood volume. After donation, your body has an amazing capacity to replace all the cells and fluids that have been lost. Take red cells.
