How does the Body Replace Blood

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.

Components of Blood

When we receive your donation we separate it into individual components by spinning it in a machine called a centrifuge. The individual components are red cells, white cells, platelets and plasma. These can all be put to different uses.
