FIELD: medicine. SUBSTANCE: method involves measuring full resistance of body tissues using four-electrode circuit under alternating electric current of 300 Hz being applied. The current is supplied through index fingers on the right and left hand. Voltage drop between the middle fingers is interpreted as testee body impedance. Impedance deviation from reference value is interpreted in terms of ethanol availability in organism tissues. EFFECT: enhanced effectiveness in detecting ethanol in human tissues; high reliability of results. 2 dwg
