Various procedures can be undertaken to produce different blood products from whole blood.

Firstly fresh whole blood once collected can be refrigeratedat 2-6<sup>o</sup>C and become '''stored whole blood''' which can be used for up to 4 weeks.
Firstly fresh whole blood once collected can be refrigerated at 2-6 <sup>o</sup> C and become '''Stored whole blood''' which can be used for up to 4 weeks.
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 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 2-6<sup>0</sup>C for 4 weeks. Fresh plasma must be used for the 6 hours following production unless it is frozen at -20<sup>o</sup>C where it becomes '''fresh frozen plasma''' and can then be stored and used for the next 2 years.
If fresh whole blood undergoes fast centrifugation (2500tr/min for 20 mins at 5 <sup>o</sup> C then both [[Plasma|plasma] and [[Erythrocytes|red blood cells]] become separated. '''Red blood cells''' can then be stored at 2-6<sup>0</sup>C for 4 weeks. Fresh '''plasma''' must be used for the 6 hours following production unless it is frozen at -20<sup>o</sup>C where it becomes '''fresh frozen plasma''' and can then be stored and used for the next 2 years.
