How Are Whole Blood Donations Used?
Whole blood is used to help patients in 2 ways. It can be transfused into a single patient. Whole blood can also be separated into its specific components of red cells, plasma and platelets. These components can be given to different patients, which is why we say that a donation of one unit or pint of whole blood can help multiple people. (Although white blood cells are sometimes used in medicine, they are not derived from a whole blood donation.)
