Stock photograph of Airman 1st Class Stephanie Ambler squeezing blood into a glass cylinder of copper sulfate solution to test for iron levels during a blood drive April 13. If blood does not drop to the bottom of the cylinder within 15 seconds, it indicates the volunteer has an iron deficiency and cannot donate. Airman Ambler is assigned to the 48th Medical Support Squadron. U.S. Air Force photo by Staff Sgt. Jeanette Copeland. [0003-0704-2600-2230] by 0003
