About Donation of Blood
Donating blood is a simple and relatively painless procedure that can help save lives. According to the American Association of Blood Banks, eight million volunteer donors donate the 14 million pints of blood used in the United States each year. The blood is used to help a variety of people. Donated blood can help restore a person's blood volume after surgery, accident, or childbirth, improve the immunity of a patient suffering from cancer or leukaemia and other diseases, and improve the blood's ability to carry oxygen. Sometimes the donated blood is used as whole blood; that is, the blood from a donor is administered in its entirety to the recipient. In other cases, the blood is separated into its components (platelets, plasma, red and white cells, and clotting factors), and administered to a patient in need of that specific component.

Characteristic of Blood
The donated blood is sealed in a special plastic bag that contains substances that will keep it from clotting (anticoagulants) and will preserve it. Refrigerated, whole blood is useable for 42 days. Blood components, however, can be preserved for much longer--in the case of red blood cells, up to 10 years, if frozen. A sample of the donated blood is taken for testing. It is checked for infections diseases like AIDS and syphilis, for anaemia, and, if the blood type is not already known, for blood typing. Human blood falls into three major groups, A, B, and O; the types get their names from certain molecules found on the surface of the red blood cells. If a person receives a donation of an incompatible blood type, the blood cells can clump together, a dangerous and possibly fatal situation. Type O blood can be received by persons with A, B, or AB blood (which is why type O is sometimes called the "universal donor"), but a person with Type O blood can only Type O blood. It is also important to match the Rh factor of the blood, which can be positive or negative.

Blood Donation

A blood donation is when a healthy person voluntarily has blood drawn. The blood is used for transfusions or made into medications by a process called fractionation. In the developed world, most blood donors are unpaid volunteers who give blood for a community supply. In poorer countries, established supplies are limited and donors usually give blood when family or friends need a transfusion. Many donors donate as an act of charity, but some are paid and in some cases there are incentives other than money such as paid time off from work. A donor can also have blood drawn for their own future use.

Types of Donation

Blood banks sometimes use a modified bus or similar large vehicle to provide mobile facilities for donation. Blood donations are divided into groups based on who will receive the collected blood. An allergenic (also called homologous) donation is when a donor gives blood for storage at a blood bank for transfusion to an unknown recipient. A directed donation is when a person, often a family member, donates blood for transfusion to a specific individual. Directed donations are relatively rare. A replacement donor donation is a hybrid of the two and is common in developing countries such as Ghana. In this case, a friend or family member of the recipient donates blood to replace the stored blood used in a transfusion, ensuring a consistent supply. When a person has blood stored that will be transfused back to the donor at a later date, usually after surgery, that is called an antilogous donation. Blood that is used to make medications can be made from allergenic donations or from donations exclusively used for manufacturing.

Recipient Safety

Donors are screened for health risks that might make the donation unsafe for the recipient. Some of these restrictions are controversial, such as restricting blood donations from men who have sex with men for HIV risk. Autologous donors are not always screened for recipient safety problems since the donor is the only person who will receive the blood. Donors are also asked about medications such as dutasteride since they can be dangerous to a pregnant woman receiving the blood. Donors are examined for signs and symptoms of diseases that can be transmitted in a blood transfusion, such as HIV, malaria, and viral hepatitis. Screening may extend to questions about risk factors for various diseases, such as travel to countries at risk for malaria or variant Creutzfeldt - Jakob disease (vCJD). These questions vary from country to country. For example, while Québec may defer donors who lived in the United Kingdom for risk of vCJD, donors in the United Kingdom are only restricted for vCJD risk if they have had a blood transfusion in the United Kingdom.
