DEXA, or DXA stands for Dual-energy X-ray Absorptiometry. This painless, non-invasive procedure scans your body as you lie on a table and only requires a few specific pre-test conditions to ensure the highest accuracy and repeatability of subsequent testing (please go here for details). The DXA scan is commonly used to measure bone mineral density for detecting low bone density or osteoporosis. It is also the current gold standard of estimating body composition or body fat percentage. Specially trained experts create and analyze a detailed report, telling you exactly how much muscle or fat you have in a given area of the body. At an additional cost, you may also choose to receive a whole body bone mineral density (BMD) screening and resting metabolic rate (RMR) estimation based on your lean mass.
The 30-minute DXA body comp will tell you all these things about your body:
- Bodyfat Percentage and how you compare against the average
- Fat Mass
- Lean Mass
- Visceral Fat Mass
- Android/Gynoid Ratio
- Regional comparisons of your arms vs. legs and left vs. right sides of your body
- Resting Metabolic Rate based on muscle mass and whole body bone density screening (at an additional cost)
A body composition test is typically repeated every 3 months and can be safely repeated as often as once a month.
