Plasma |
The fluid portion of the whole blood. It is composed of 90% water, 7-8% soluble proteins, 1% inorganic salts and approximately 2% organic molecules. Plasma is collected using an
anti-coagulant (agents which prevent clotting); ACD, CPD, CPDA-1 and sodium citrate are common anti-coagulants. GWB can provide all of the plasma types listed with these anti-coagulants (Heparin and EDTA are available). |
|
Source Plasma |
Individual donor units are removed from the person (usually by plasmapheresis, which returns the formed elements of the blood such as the red blood cells to the donor) and frozen after filling into appropriate containers. If plasmapheresis is not used, the red blood cells must be removed immediately. The plasma is stored at -20°C. |
|
Fresh Frozen |
Frozen within six hours after phlebotomy (removal from the donor) at <-18°C. |
|
Liquid Plasma |
Red blood cells must be removed from the plasma within twenty-six days of phlebotomy and stored at 2-8°C within four hours from collection. |
|
Recovered Plasma |
Liquid plasma that has become outdated for intravenous use. |
|
Whole Blood |
Consists of plasma and formed elements such as red blood cells, white blood cells, and platelets. |
|
Off the Clot Serum |
Whole blood is collected without an anti-coagulant. Blood is immediately centrifuged and the serum is separated from the red blood cells. The serum is allowed to clot at room temperature and then is centrifuged to remove the clot. Serum is stored at -20°C. |
