When you make a double red cell donation, you give two units of red blood cells in one appointment. Your fluids, plasma, and platelets are returned to your body. In two donations, you give the same number of life-saving red cells as you would during four whole blood donations.
Blood types most needed: O+, O-, A-, B-
Type O donors are especially needed for double red cell donation, especially O- donors. Type O- donors are universal red cell donors, meaning their red cells can be given to anyone in need.
