Blood collection tubes are prepared for use July 8, 2019, at McConnell Air Force Base, Kan. The colors differentiate the use of the tube for specific tests. Blood is collected for blood count, chemistry, glucose and other tests that are not available at McConnell and must be shipped to other installations for results.
