What are double red cells?
Blood is made up of three basic components: red cells, plasma, and platelets. Double red cells are two units of only red cells.
How are double red cells collected?
Through a single sterile needle, some of your whole blood is removed and passed through a cell separator. The whole blood is separated into red blood cells and plasma/platelets. The red cells are then drawn into collection bags, while the cell separator returns the plasma/platelet product and saline solution to the donor. The saline solution provides volume replacement to replace the volume of blood lost by the donor.
Why donate double red cells?
- In approximately 45 minutes, you are able to donate two products in one visit.
- Provide a better product for the recipient as it reduces patient transfusion risk by reducing the number of donor exposures.
- 112-day deferral time between donations results in fewer phone calls and/or emails asking you to donate: longer deferral time between donations means fewer trips to the Blood Donor Center, saving you time and gas.
- Lower total blood volume loss because you receive plasma/platelet and saline solution back. You leave more hydrated!
- Smaller needle.
- Universal donors with type O blood are encouraged to try a double red cell donation.
