Bodystat QuadScan 4000 vs InBody 380

Bodystat QuadScan 4000 and InBody 380: 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 380: when to consider it

For following fat and muscle changes at a gym, nutrition practice or mobile testing event. Adds a body-water ratio and whole-body phase angle to the usual overview for discussion during a consultation.

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.
