| Granulocyte concentrates | Blood components collected by cytapheresis or manufactured from whole blood donations; an apheresis granulocyte should contain a minimum of 1.0 × 1010 granulocytes. |
| Plasma | General term for a blood component prepared from whole blood or apheresis that contains only the plasma portion of whole blood |
| Platelets | A concentrate of platelets separated from a single unit of whole blood; should contain a minimum of 5.5 × 1010 platelets |
| Pooled platelets | Whole blood–derived platelets (4–5 units) of the same ABO/Rh type are pooled into a single bag for adult transfusion. |
