The components (“ingredients”) of human blood, for example, red cells, white cells, plasma, and the antihemophilic fraction. Blood components can be separated out by a process called “fractionation.” When whole blood is not needed, each blood component can be administered by itself, with greater benefit and safety to the patient than whole blood. Furthermore, each unit of whole blood “goes farther” (can be used to treat more patients) when it is distributed as blood components.
Any transfusible product derived from whole blood (e.g., red blood cells, platelets, plasma, coagulation factors, immunoglobulins).
