Individuals may donate plasma through a process called plasmapheresis. Plasmapheresis is a sterile, self-contained, automated process, which separates plasma from other cellular components, which are then returned to the donor.

One patient wanting to treat primary immunodeficiency disease needs 130 donations. About 900 donations are needed to treat alpha-1 antitrypsin deficiency, and 1200 donations are required to treat one patient with Hemophilia A.
