==Production of Blood Products==
Various procedures can be undertaken to produce different blood products from whole blood.
If fresh whole blood undergoes slow centrifugation (1100tr/min for 10 mins at 22<sup>o</sup>C) then Platelet rich plasma is produced. This can be stored for 3 days at an ambient temperature.
If fresh whole blood undergoes fast centrifugation (2500tr/min for 20 mins at 5<sup>o</sup>C then both plasma becomes separated and red blood cells. Red blood cells can then be stored at 2-60C for 4 weeks. Fresh plasma must can only be used for the 6 hours following production unless it is frozen at -20oC where it becomes '''fresh frozen plasma''' and can then be used for the next 2 years.
