In modern medical treatments, patients may receive a pint of whole blood or just the specific components of the blood that are needed to treat their particular condition. This approach to treatment, referred to as blood component therapy, allows several patients to benefit from one pint of donated whole blood.
The transfusable components that can be derived from donated blood are red cells, platelets, plasma, cryoprecipitated AHF (cryo), and granulocytes. An additional component, white cells, is often removed from donated blood before transfusion.
