Bodystat QuadScan 4000 vs InBody 230
Bodystat QuadScan 4000 and InBody 230: 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 230: when to consider it
InBody230 is an older model you may encounter at nutrition practices. It helps put weight changes in the context of fat and muscle. Testing is most useful with results explained and compared with previous visits.

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.
