Blood donors are vital
Army Sgt. Daniel Llenas, a lab technician with the 932nd Blood Support Detachment at Joint Base Balad, Iraq, prepares an arm resting table March 4, 2010, for a platelet donor. The technicians use an Apheresis machine that draws the blood, separates the platelets and then returns the blood to the donor. The procedure takes approximately one and a half to two hours. Sergeant Llenas is deployed from Fort Hood, Texas, and is a native of Juneau, Alaska. (U.S. Air Force photo/Master Sgt. Linda C. Miller)
