Bodystat QuadScan 4000 vs InBody 520
Bodystat QuadScan 4000 and InBody 520: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
Bodystat QuadScan 4000: when to consider it
QuadScan 4000 measures impedance at four frequencies using adhesive electrodes. Alongside estimated fat and fat-free mass, it reports body-water compartments, resistance, reactance and phase angle. Testing is supine; the operator enters height and weight.
InBody 520: when to consider it
An older model for following fat, muscle and water during nutrition or exercise changes, and for understanding past results. Includes ECW/TBW and lean-mass distribution across the arms, legs and trunk.

Fat-free mass is not pure muscle mass. A single result is not a diagnosis. Different devices and similarly named metrics may use definitions that are not interchangeable.
