Red blood cells are the most frequently used blood component. They carry oxygen to all parts of the body and makeup 40 to 50% of blood volume. Red blood cells are used for surgical operations, to treat anemia, and to replace blood lost due to trauma resulting from accidents or injuries.
What is a Double Red Donation?
A double red cell donation is similar to a whole blood donation, but a special device is used to separate the red cells from the donor’s blood, allowing them to donate twice the amount of red blood cells during one visit. The plasma, platelets and other blood components are returned to the donor.
A double red cell donation takes 30 to 40 minutes; the entire visit takes about an hour and 15 minutes, a bit longer than a whole blood donation.
A donor can give double red cells every 112 days.
