An American Red Cross technician applies a label to one of many vials that will be used during blood donation at the Red Cross mobile blood drive at the Sports and Fitness Center June 23, 2010, at Joint Base Charleston, S.C. The vials are drawn from a smaller bag that collects blood before the donation begins using tubing and a needle. The American Red Cross collected 26 pints from ALYX Component Collection System donors, 77 pints from standard donors and 103 pints total. Through ALYX, donors are able to give two units of red cells during one visit, providing double the impact for patients requiring the most critically needed blood types.

U.S. Air Force Tech. Sgt. Lester Crim sits among other ALYX doners waiting for Red Cross technicians to prepare them before donation at the Red Cross mobile blood drive at the Sports and Fitness Center June 23, 2010, at Joint Base Charleston, S.C. The ALYX donation uses the ALYX Component Collection System to collect two pints of red blood cells in one sitting. The ALYX system uses a centrifuge to separate the red blood cells from the plasma and platelets. After seperating blood cells, the machine returns plasma and platelets with some added saline solution. Sergeant Crim is a jet engine mechanic with the 315th Maintenance Squadron.

U.S. Air Force Tech. Sgt. Lester Crim squeezes a stress pad to build up pressure, allowing for easier collection through the ALYX Component Collection System at the Sports and Fitness Center June 23, 2010, at Joint Base Charleston, S.C. The Red Cross is targeting donors with O-type blood for the new device because the blood is universal and the most used blood at hospitals. Also being targeted is A negative and B negative blood. The ALYX donation takes 10 to 15 minutes longer than a conventional donation, but is otherwise no different to the donor. After the ALYX donation, the donor is advised not to donate again for 112 days due to the long period the red blood cells take to regenerate.
