Bodystat QuadScan 4000 vs Nutriguard-MS
Bodystat QuadScan 4000 and Nutriguard-MS: 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.
Nutriguard-MS: when to consider it
Nutriguard-MS measures bioelectrical impedance at 5, 50 and 100 kHz. Standard testing uses four adhesive electrodes on the hand and foot of one side. Body-composition and water estimates are evaluated from resistance and reactance using the relevant software; regional mode requires the appropriate procedure.

| Specifications | Bodystat QuadScan 4000 | Nutriguard-MS |
|---|---|---|
| Method | Multi-frequency BIA | Multi-frequency BIA |
| Measurement frequencies | 5, 50, 100, 200 kHz | 5, 50, 100 kHz |
| Measurement position | Supine | Not verified |
| Electrodes | 4 adhesive electrodes | 4 adhesive electrodes for whole-body testing |
| Documented outputs | Estimated fat, fat-free mass, total, intracellular and extracellular water; 50 kHz phase angle | Resistance and reactance; body-composition interpretation through software |
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.
