Automated bioimpedance measurement systems are part of modern medicine because they provide the ability to determine body composition and provide performance parameters. Bioimpedance analysis has the advantage of being  able to test non-invasively, and accuracy and availability continue to improve every year. Currently, when assessing bioimpedance parameters, special attention is paid to the methods and accuracy of measurements. This  article discusses key aspects of bioimpedance determination related to measurement errors. Various approaches to reducing errors in bioimpedance measurements are also presented.
