The BODPOD Gold Standard Body Composition Tracking System is an air displacement plethysmograph which uses whole-body densitometry to determine body composition (fat and fat-free mass) in adults and children, and can accommodate a wide range of populations. A full test requires only about 5 minutes, and provides highly accurate, safe, comfortable, and fast test results. Each BOD POD Gold Standard is a complete turnkey system with a dedicated computer system, the ability to measure thoracic gas volume (TGV), and data management capabilities.
