Blood Donation.

overview:

Blood donation is a voluntary process that can help save other people’s lives, there are several blood donation types that help meet various medical needs, blood donation,

Also known as blood banking, refers to the collection, testing, preparation and storage of whole blood and blood components primarily intended for transfusion, blood donors are typically unpaid volunteers, but business blood donation and processing companies, such as independent blood banks and donor centers, can also pay for them.

Blood registry refers to the collection and sharing of blood donation and  donor data, a confidential national database known as the donor deferral register lists donors who have been determined to be temporarily or permanently unable to donate blood.

The National Blood Data Resource Center reports that in the United States  about 13.9 million whole blood units (one whole blood unit is equal to 450 ml or about 1 pt) are donated annually, of which about 695,000 are autologous donations for elective surgery.

This practice is critical to meeting the constant blood demand, more than four million people in the United States require blood transfusions every year, approximately 26 million transfusions are administered either as whole blood or as whole blood components.

For example, approximately 34,000 units per day are transfused as red cells.
