Plasma is the pale-yellow liquid part of whole blood, in which the cellular elements are suspended. It is enriched in proteins that help fight infection and aid the blood in clotting.
Plasma collected from blood group AB donors is considered "universal donor" plasma because it is suitable for all recipients, regardless of blood group. Due to its value as a transfusion component, it is sometimes referred to as "liquid gold." Plasma donors of other blood types are also welcome!
Plasmapheresis is the procedure by which plasma is separated from whole blood and collected. Blood flows through a single needle placed in an arm vein, into a machine that contains a sterile, disposable plastic kit. The plasma is channeled out into a special bag, and red blood cells and other parts of the blood are returned to you through the same needle.
Donors must lack plasma proteins (antibodies) directed against blood cell elements, that could end up being harmful to recipients. Otherwise, eligibility for plasmapheresis procedures is the same as that for whole-blood donation.
Time it Takes
Plasmapheresis procedures take about 40 minutes, but you should allow another 20 minutes for staff to obtain your medical history. Every effort will be made to make the experience relaxing and enjoyable.
Frequency
The interval between consecutive group plasmapheresis donations at NIH is one month.
Please note that plasma donation for transfusion to patients is not compensated.
