Staff Sgt. Edward Thompson, NCO in charge of Hematology and Urinalysis at the 6th Medical Group, looks at a sample through a microscope, Feb. 18, 2020, at MacDill Air Force Base, Fla. Using the microscope, Thompson looks at red blood cells, white blood cells, and platelets checking for abnormalities, which allows him to determine if a patient has a disease such as Malaria or Lukemia.
