Blood is donated as Whole Blood (WB)
Blood can be stored as WHOLE BLOOD, or, much more usefully processed to packed red blood cells in which about 70-90% of the plasma has been removed. this is done by centrifuging the unit of blood.
The top layer after centrifugation, i.e. platelet rich plasma (PRP), is expressed into a satellite bag, leaving PACKED RED BLOOD CELLS (PC) in the primary bag.
The platelet rich plasma is centrifuged a second time to separate the PLATELET CONCENTRATE (PLC) at the bottom of the bag. The supernatant plasma is expressed into a third bag and stored as FRESH FROZEN PLASMA (FFP).
Some clotting factors from FFP may be separated out as CRYOPRECIPITATE when required for specific conditions.
A single donation of whole blood supplies three separate components (packed red blood cells, platelet concentrate and fresh frozen plasma) that are used to treat three different patients.
Besides separation into components each unit of blood undergoes a battery of tests to ensure that it is free from infections that can be transmitted through blood. These tests are for HIV, I&II, HBsAg, HCV, HBcAb, Malaria, VDRL. Only units negative for all these tests are taken forward to be used for patients.
