Medical laboratory: where science, medicine converge
Staff Sgt. Lindsay Palson, 51st Medical Support Squadron medical laboratory technician, observes a joint fluid specimen under a microscope in the 51st Medical Group at Osan Air Base, Republic of Korea, April 17, 2014. Palson examined the fluid for the presence of white cells which can indicate an infection, or a high number of red and white cells that indicates the sample was improperly aspirated when it was taken from the patient.
