Air Force medical laboratories – a culture all their own
A laboratory technician guides a needle to draw blood from a patient's vein in the 51st Medical Support Squadron laboratory at Osan Air Base, Republic of Korea, Oct. 21, 2015. The lab houses a blood bank that holds no less than four 500ml units of blood for emergency use. The lab can also test a pregnant woman's blood type to determine if she could be incompatible with the unborn child. If an incompatibility is identified, a doctor will prescribe a drug to counteract the body's reaction. (U.S. Air Force photo/Tech. Sgt. Travis Edwards)
