Bone marrow
MCCONNELL AIR FORCE BASE, Kan. -- 1st. Lt. James Clark, 22nd Medical Support Squadron briefs McConnell Airmen about the new procedures for testing bone marrow at the base medical clinic, Oct. 2. The procedure is like that of a fingerprint. An individual takes a cotton swab to his mouth and swabs for 30 seconds. The swab is then attached to a paper with the individual’s information, tested and the results stay in the person’s medical file for the rest of their life. (Photo by Senior Airman Laura Suttles)
