ACCUNIQ BC720 vs Bodystat QuadScan 4000
ACCUNIQ BC720 and Bodystat QuadScan 4000: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
ACCUNIQ BC720: when to consider it
ACCUNIQ BC720 uses multi-frequency BIA with eight contact electrodes. Results include estimated whole-body and regional fat and muscle for the arms, legs and trunk. BC720 also reports extracellular water and phase angle.
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.

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.
