Adopting bioinduction technology combined with human electrical impedance measurement technology, HRA-II applies 1.3V voltage to the human body through six sensors respectively (two on forehead, two on hands and two on feet), conducts data collection, compares with the standard database, issues 220 impedance values of nine major human systems, and finds early diseases. The whole examination process lates 5'38", no radiation, no trauma, no fasting, no blood drawing, 96% compliance in clinical trials. HRA has got CE certificate and FDA approved.
