There is always a need for blood donors. Modern medical care, including surgery and medical treatment for many diseases, is not possible without the use of blood products. There never used to be debate over when someone was dead. If there was no heartbeat, no breathing, and no response to stimulation or resuscitation for a sufficient period of time, it was clear that the death of the person had occurred. It is necessary for the heart to be beating and blood, carrying oxygen, to be pumping in and out of such organs at the time of removal.

Therefore, the desire for vital organs for transplantation prompted some to look for new and different criteria to declare death which would allow functioning organs to be removed from the patient.

A blood donation occurs when a person voluntarily has blood drawn and used for transfusions or made into medications by a process called fractionation.

Potential donors are evaluated for anything that might make their blood unsafe to use. The screening includes testing for diseases that can be transmitted by a blood transfusion, including HIV and viral hepatitis.

The donor must also answer questions about medical history and take a short physical examination to make sure the donation is not hazardous to his or her health. How often a donor can give varies from days to months based on what he or she donates and the laws of the country where the donation takes place

The amount of blood drawn and the methods vary. The collection can be done manually or with automated equipment that only takes specific portions of the blood. Most of the components of blood used for transfusions have a short shelf life, and maintaining a constant supply is a persistent problem.
