LOINC description : Dual-energy X-ray absorptiometry (DXA) is one of the most widely used methods to assess
body composition. A densitometer scanner device is used to scan the entire body or
specific body sites such as the hip, spine, and limbs. DXA uses X-ray energy to measure
body fat, muscle, and bone mineral and as a result, a small amount of radiation is
delivered to the body during the DXA scan procedure. The results from a whole body
DXA scan can be used to estimate total mass (gm), bone mineral content (BMC) (gm),
bone area (cm2), bone mineral density, fat mass, lean mass excluding BMC (gm), lean
mass including BMC (gm), and percent body fat (%). DXA scanner manufacturers produce
special software that is used to analyze the DXA scan data to produce body composition
results. Source: Centers for Disease Control and Prevention, National Center for Health

January 22, 2009). The study of body composition looks at the differences in bone,
muscle, organs, and fat. Body composition analysis is an indicator of overall health
as determined by a person's percentage of fat and lean mass. Body composition tests
are designed to give a whole picture of the body. This information is useful to help
develop nutrition and exercise programs to benefit the individual.;
