The Bodystat advantage

The Bodystat range of devices and software offer the medical profession numerous benefits.

Monitor to improve patient recovery times, save time with faster ongoing measurement, increased analysis of whole body composition, cellular health analysis and much more. Utilising bioelectrical impedance technology, extensively used in research, Bodystat pioneer industry leading devices for the medical and research industry.

Bodystat advantages for medical


Our dual frequency BIA device is the Bodystat 1500MDD which features the advanced BIAS Body Manager Pro Software. Lightweight, portable and non-invasive, the 1500MDD delivers results in seconds, including body fat, lean weight, intra-cellular and extra-cellular water and nutritional health assessments. The MDD can also be used to assess body composition and nutrition status in children, since the MDD is accurate for ages 6 and over. Visit the 1500MDD 'product' page for full information.

Understanding the importance of BIA

Bioelectrical Impedance Analysis (BIA) measures the impedance or opposition to the flow of an electric current through the body fluids contained mainly in the lean and fat tissue. Impedance is low in lean tissue, where intracellular and extracellular fluid and electrolytes are primarily contained, but high in fat tissue. Impedance is thus proportional to body water volume (TBW). In practice, a small constant current, typically 400 uA at a fixed or multi frequencies are passed between electrodes spanning the body, and the voltage drop between electrodes provides a measure of impedance. Prediction equations, previously generated by correlating impedance measured against an independent estimate of TBW, may be used subsequently to convert a measured impedance to a corresponding estimate of TBW. Lean body mass is then calculated from this estimate using an assumed hydration fraction for lean tissue (NOTE: Bodystat is unique in using their own regression equation for this calculation and not the assumed 73.2% used by other manufacturers). Fat mass is calculated as the difference between body weight and lean body mass.

The impedance of a biological tissue comprises two components, the resistance and the reactance. The conductive characteristics of body fluids provide the resistive component, whereas the cell membranes, acting as imperfect capacitors, contribute a frequency-dependent reactive component. By measuring the impedance at 50 kHz and 200 kHz and by applying predictive equations, it is possible to estimate both extra-cellular water (ECW) and TBW respectively and by deduction, intra-cellular water (ICW). ECW can be related to extra-cellular mass (ECM) and ICW to body cell mass (BCM).
