A blood donation occurs when a healthy person voluntarily has blood drawn and used for transfusions to the patient or receiver or made into biopharmaceutical medications by a process called fractionation (separation of whole-blood components). Donation may be of whole blood, or of specific components directly (the latter called apheresis). Blood banks often take part in the collection and storage process as well as the procedures that follow it. Most blood donors are unpaid volunteers who donate blood for a community supply. Many donors donate the blood as an act of charity. In some countries that allow paid donation some donors are paid.
