      Storage: 1-6° C for up to 35 days

Red Blood Cells (RBCs):
      Prepared from whole blood after removal of plasma or collected using an apheresis machine(2 unit).
      Used to increase oxygen carrying capacity           
      Storage: 1-6°C for up to 42 days

Fresh Frozen Plasma (FFP):
     Prepared from whole blood or using an apheresis machine.
     Used to treat patients with multiple coagulation factor deficiency who are bleeding or who will be undergoing an invasive procedure.

Platelets:
     Prepared from whole blood (not <20°C) within 4 hrs or by using an apheresis machine.
                   Used of thrombocytopenia in bleeding patients (<50,000/ml)
                   Storage: 20-24°C with agitation for up to 5 days

Cryoprecipitate:
       Prepared from the insoluble portion of FFP when it is hawed at 1-6°C, and is refrozen within 1 hr of preparation.

                    Thawed at 20-24°C for up to 6 hours

Granulocytes:
       Prepared from whole blood or apheresis (mostly apheresis).
            Can be harvested in buffy coats (UK)
       Used when patient has an infection, neutropenia, a failure to respond to antibiotics, myeloid hypoplasia, and a reasonable chance of recovery.
