Key stats
How close Prism scans land to clinical reference, and how steady they stay across repeat scans. Tap any card for the full breakdown.
Body composition
3 key metricsBody Fat %
How close Prism's body-fat estimate lands to a DXA scan, and how much it drifts when the same person is scanned twice.
On the same scale as DXA's own day-to-day spread.
Visceral Fat
Deep abdominal fat surrounding the organs — the strongest single body-composition signal for cardiometabolic risk.
On the same scale as DXA's own VAT precision.
Appendicular Lean Mass
Lean tissue in the arms and legs as a share of body weight — the standard readout for tracking muscle, strength, and aging.
Within DXA's own ALM noise band.
Measurements
3 key metricsBMI
Body Mass Index inferred from the scan's volumetric estimate of mass and height — no scale, no tape measure needed.
Far tighter than self-reported BMI.
Chest
Chest circumference at the widest point across the bust/pectorals — a primary anchor for clothing fit and upper-body sizing.
Tighter than a trained tape-measure expert.
Waist
Waist circumference at the natural waist — the most-used single number for cardiometabolic risk and clothing fit.
Tighter than a trained tape-measure expert.
* Athlete Mode (coco2_adaptive) further tightens accuracy for subjects whose body composition sits at the boundaries of the standard model — see Body composition for the breakdown.
