Blood donation is a voluntary procedure that can help save the lives of others. There are several types of blood donation, which help meet different medical needs.
Whole blood donation
This is the most common type of blood donation, during which you donate about a pint of whole blood. The blood is then separated into its components — red cells, plasma, platelets.
During apheresis, you are hooked up to a machine that can collect and separate blood components, including red cells, plasma, platelets, and return unused components back to the donor.
Platelet donation (plateletpheresis) collects only platelets — the cells that help stop bleeding by clumping and forming plugs (clotting) in blood vessels.
Donated platelets are commonly given to people with leukemia, people receiving chemotherapy and babies with severe infections.
Double red cell donation allows you to donate twice the amount of red blood cells than you normally would during a whole blood donation. Red blood cells deliver oxygen to the entire body.
People with a medical need for only red blood cells include those with severe blood loss, such as after an injury or accident, and those who have anemia with serious symptoms
Plasma donation (plasmapheresis) collects the liquid portion of the blood (plasma). Plasma helps blood clot and contains proteins and other substances, such as electrolytes, that help the body function normally.
Plasma is commonly given to people with liver conditions, burns and severe bacterial infections in their blood.
