What Your DEXA Scan Measures
A DEXA scan separates your body into three precise measurements:
Lean Mass — the muscle you build and maintain
Fat Mass — total body fat, by location
Bone Density — an indicator of bone strength.
Unlike smart scales that estimate through bioimpedance (electrical signals), DEXA uses low-dose X-rays for clinical accuracy (±2% on fat and lean mass).
The difference matters: A smart scale might say 25% body fat. DEXA might show 31%. That's 15+ pounds of hidden fat your scale didn't see.
The DEXA Scan Experience
Scan Time

Results
How it works: You lie on a padded table, fully clothed. A scanning arm passes over your body (non-invasive). No injection, no special prep. Results are ready the same day.
Radiation: A DEXA scan delivers <30µSv per scan of radiation, which is less than a cross-country flight and within FDA safety guidelines.

Why Accuracy Matters: DEXA vs. Your Scale
Smart Scale
At home
✕ Estimates body fat using bioimpedance (electrical signals through your legs)
✕ Can be off by 10–20%
✕ Reacts to hydration, time of day, food in your stomach
✕ Same price as DEXA, less accurate
