DEXA vs BIA Body Composition
DEXA is the clinical gold standard for body composition — directly measures bone, lean mass, and fat by region. BIA estimates the same via electrical conductance and is sensitive to hydration. DEXA is decisive for baseline; BIA is appropriate for high-frequency trend.
DEXA is decisive at baseline and at the recalibration cadence — regional fat and visceral fat readings drive optimization.
BIA is appropriate as a daily trend tool when calibrated against DEXA — it should not be the decisional marker.
Educational. Final pathway selection is provider-reviewed via synchronous video consultation against your biomarkers, history, and goals.
Frequently asked
Can BIA replace DEXA?
No — BIA can supplement DEXA between scans but does not replace it for decisional use.
How often should DEXA be repeated?
Typically at baseline and at each major recalibration window — provider-reviewed cadence.
Take the optimization assessment.
The adaptive assessment maps your symptoms, history, and goals to candidate pathways — and routes you into provider review.
