Body composition/bone density evaluation

  • Hydrostatic weighing assessment


This test measures the amount of total lean (muscle, bones, organs, blood, connective tissue etc.) and fat tissue of the body. During this test, a subject sits in a tank of warm water (similar to a Jacuzzi) up to the level of the shoulders. The subject forcibly exhales all the air from the lungs and puts the head below water and holds breath for a count of about 5 to 10 seconds.  This procedure is repeated about 3 to 6 times.

  • DEXA

Lean body mass (LBM), fat mass and bone mass will be measured using a DXA machine (GE Luna).  DEXA is an enhanced form of x-ray technology. The effective radiation dose from this procedure is about the same as the average person receives from background radiation in one day.  It is a painless procedure.
