300 Longwood Avenue Boston, MA 02115 (617) 355-6000 About Us: Automated Red Cell An Automated Red Cell Collection selectively separates the red cells and plasma blood components as the blood is drawn and immediately returns the rest to the donor. Automated Red Cell Donations use a cell separator to draw blood and provides volume replacement (saline solution) to replace the volume of blood lost by the donor. Your donation will result in two red cell transfusions for patients (this is less blood volume than when you give whole blood but a more concentrated and consistent product for patients). Volume replacement should help you feel more comfortable after the procedure. This type of donation is perfect for donors who are unable to travel to Children's to donate frequently. Points of Interest: 2RBC takes just 30 minutes longer than a whole blood donation. Females must weigh at least 150 lbs and be at least 5'5". Males must weigh at least 130 lbs and be at least 5'1" tall. The maximum donations possible in a year is reduced from 6-3. 2RBC can be donated every 112 days. You can give twice as much in just one visit to the blood donor center. Appointments are typically required.
