An impedance measurement system for performing a bioimpedance measurement on a biological subject, the system including a signal generator configured to apply alternating signals to at least part of the biological subject at a plurality of different frequencies, a sensor configured to measure response signals from the biological subject and one or more electronic processing devices that determine impedance values obtained at the plurality of different frequencies using the measured response signals, calculate an impedance curve using a curve fitting algorithm, determine a deviation of the impedance curve from the impedance measurements and use the deviation to perform an evaluation of the impedance measurements. 一种用于对生物受试者执行生物阻抗测量的阻抗测量系统，所述系统包括信号发生器，其被配置成将多个不同频率的交流信号施加至生物受试者的至少部分；传感器，其被配置成测量来自该生物受试者的响应信号；以及一个或更多个电子处理设备，其使用测量到的响应信号确定在该多个不同频率下获得的阻抗值，使用曲线拟合算法计算阻抗曲线，确定该阻抗曲线与该阻抗测量的偏差，以及使用该偏差来执行对阻抗测量的评估。
