Plasma donation
The donation of sale of blood plasma for use in medical or other products.
Unlike blood donors, most plasma 'donors' in the US are paid.
The procedure is done in a walk-in facility, where whole blood is taken through an IV needle, and separated into plasma and blood cells.
The blood cells are then returned intravenously to the donor.
As long as the IV needles are disposable and not reused, there is no danger of infection for plasma donors
