Blood donation
About this test
Blood donation is a voluntary procedure that can help save lives. There are several types of blood donation. Each type helps meet different medical needs.
Why it's done
You agree to have blood drawn so that it can be given to someone who needs a blood transfusion. Millions of people need blood transfusions each year. Some may need blood during surgery. Others depend on it after an accident or because they have a disease that requires certain parts of blood. Blood donation makes all of this possible. There is no substitute for human blood — all transfusions use blood from a donor.
Risks and complications
Blood donation is safe. New, sterile disposable equipment is used for each donor, so there's no risk of getting a bloodborne infection by donating blood. Most healthy adults can donate a pint (about half a liter) safely, without health risks. Within a few days of a blood donation, your body replaces the lost fluids. And after two weeks, your body replaces the lost red blood cells.
