WebBioimpedance Analysis. Bioimpedance analysis (BIA) is a method of estimating body fluid volumes by measuring the resistance to a high-frequency, low-amplitude alternating electric current (50 kHz at 500 to 800 mA). The amount of resistance measured ( R) is inversely proportional to the volume of electrolytic fluid in the body and to a lesser ... WebThaw vial of dye. 2.
