The QuadScan 4000 is a 4 frequency device offering accurate body composition, hydration and cellular health assessment using bioelectrical impedance analysis.
One of the values displayed on the QuadScan is the Prediction Marker. The objective of Bodystat’s unique Prediction Marker is to provide health professionals with a tool for early detection of changes in the ECW/TBW ratio before it becomes clinically obvious.
Healthy individuals tend to have a lower Prediction Marker while the unhealthy have higher values. The lower the marker, the healthier and more hydrated the body cells; the higher the marker, the less healthy.
The QuadScan 4000 also displays the Phase Angle value. Phase Angle is a measurement at 50 kHz relating to the function & integrity of the cell membrane and thus overall cellular health.
Phase Angle is made up of two components: resistance and reactance. The higher the Phase Angle the healthier the cells. The Phase Angle records the voltage drop in an applied current. The voltage drop is larger if the reactance (i.e. the ability of the cell to react with the current) is larger which only occurs in a healthy functioning cell membrane.
Phase Angle has been found as a useful prognostic indicator of ill health such as malnutrition, cancer and other potentially serious diseases.
