A blood bank is a center where blood gathered as a result of blood donation is stored and preserved for later use in blood transfusion. The term “blood bank” typically refers to a division of a hospital where the storage of blood product occurs and where proper testing is performed (to reduce the risk of transfusion related adverse events). However, it sometimes refers to a collection center, and indeed some hospitals also perform collection. Blood banking includes tasks related to blood collection, processing, testing, separation, and storage.
