A
blood bank is a cache or bank of
blood or
blood components, gathered as a result of
blood donation or collection, 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.
