Prediction Marker & Impedance Ratio
What is Prediction Marker/Impedance Ratio (IR)?
The Impedance Ratio is derived by a Bioelectrical Impedance Analysis (BIA) measurement. A small current is used to measure the resistance at difference frequencies against the various tissues in the body. The impedance readings are then translated using validated algorithms. The Impedance Ratio is the ratio between the impedance measured at 200 kHz and 5 kHz.
how does it work?
At 5 kHz (in a healthy subject), the resistance to the flow of the current will be High because the current cannot penetrate the cell membrane. It therefore only measures the Extra-cellular water (ECW). At the higher 200 kHz frequency, the current is powerful enough to penetrate the cell membrane. Therefore, it is ideal to measure both inside (ICW) and outside the cells (ECW). We can then observe the variance between these two values to determine the health of the body tissues.
