The blood supply system in the United States has developed along two main tracks (see Chapter 2). One involves nonprofit community, regional, and national blood centers that obtain cellular elements and plasma from whole blood or apheresis donations provided almost exclusively by unpaid volunteers. Most of these products are used directly for transfusion.

The other blood collection system involves large‐scale collection of plasma by plasmapheresis. This system consists of for‐profit organizations and almost all of this plasma comes from paid donors. This plasma is manufactured into plasma derivatives, such as albumin, coagulation factor concentrates, or intravenous immunoglobulin, and these are sold on the national and international market.
