About the study

The aim of this study is to develop a dataset with reference body composition measurements using criterion methods. This dataset will be used to develop new protocols to study patients with cancer. Obtaining measurements of sodium bromide (NaBr), deuterium dilution (D2O), and D3-Creatine in a stratified sample of adults will determine the accuracy (and precision) of the available devices for ECW, TBW, and skeletal muscle mass measurements.
