Inbody composition scale is one of the most accurate non-invasive methods of analyzing segmental fat, muscle, and total body water. It also measures and tracks inflammation, swelling, and joint injuries by comparing extracellular water to total body water. It measures bio-electrical impedance, or the flow of electrical current through body tissue, to estimate the amount of body fat, lean muscle, and water in the body. Compared to the gold standard DEXA scan, Inbody is 98.4% accurate.
