Donating Double Red Cells

Double Red Cell donations take place through an automated donation procedure that allows the donor to “double their giving” by donating two units of red cells at one time, thus providing larger volumes of blood to meet patient need.

This is possible because the automated donation procedure allows the Blood Center to collect only the desired blood component (red blood cells) and return the remaining components (platelets, plasma and white blood cells), as well as a fluid replacement solution to the donor.

The technology utilizes a centrifuge that spins and separates the blood into the desired red cell components. A machine housing a sterile centrifuge takes blood from the donor through a small needle connected to tubing. The blood is then drawn by a series of pumps into the centrifuge, which spins and separates it into the desired components.

Due to continually shifting patient need and the demands of the blood supply, Double Red Cell donation is not always appropriate for every blood type. Most donors who have an Rh-negative blood type, particularly O-negative donors, are ideal for Double Red Cell donation because there is always a strong demand for Red Blood Cells from such donors.

Most donors who are eligible to give whole blood will meet the requirements for Double Red Cell donation. Please ask your MVRBC phlebotomist about the optimal donation procedure for your blood type.

Donors who give Double Reds can make a greater impact on the blood supply with fewer visits to a donor center or mobile site, which has proven to be a great benefit for donors who are not able to donate as frequently as they would like.
