Plasma |
The fluid portion of the whole blood. It is composed of 90% water, 7-8% soluble protein, 1% inorganic salts, and approximately 2% organic molecules. Plasma is collected by 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 as well).

TYPES OF PLASMA
|
|
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 (RBC) to the donor) and frozen after filling into appropriate containers. If plasmapheresis is not used, the RBC must be removed immediately. The plasma is stored at -20°C. This material is intended for further manufacturing and cannot be used for intravenous administration.
|
|
Fresh Frozen |
Frozen within six (6) hours after phlebotomy (removal from the donor) at <-18°C.
|
|
Liquid Plasma |
Plasma must be removed from the RBC within 26 days of phlebotomy and stored at 2-8°C within four (4) hours from collection. Normally used for IV application.
|
|
Recovered Plasma |
Liquid plasma that has become outdated.
|
|
Whole Blood |
Consists of plasma, the fluid portion, and formed elements such as red blood cells, white blood cells (WBC), and platelets.
|
|
Off the Clot Serum |
Whole blood is collected without anti-coagulant. Blood is immediately centrifuged and the serum is separated from the RBC. Serum is allowed to clot at room temperature and then is centrifuged to remove the clot. Serum is stored at -20°C.
