The APL specializes in body composition measurement and validation. It is one of few laboratories in the country that implements a multi-compartment gold-standard method for measurement.  Available technology includes dual energy x-ray absorptiometry (DXA), air displacement plethysmography (BodPod), bioelectrical impedance analysis (Impedimed SFB7; InBody 720), ultrasound (B-Mode, GE logiq-e; A-Mode, Intelametrix Bodymetrix).

Dual energy x-ray absorptiometry (DXA); iDXA, General Electric. The DXA is a 3-compartment body composition method that provides measurements of fat mass, lean mass, bone mineral content, and visceral fat. The DXA takes 7-13 minutes.








Air Displacement Plethysmography (BodPod, Cosmed) relies upon a pressure volume relationship to determine body volume, which can then predict fat mass, fat free mass, and percent body fat. The ‘egg’ takes about 10 minutes for measurement










Body composition can be estimated by measuring total body water. Our laboratory utilizes 2 devices for this measurement; a multi-frequency unit (BIS; Impedimed, SFB7) and the InBody 720.  These devices provide details of intra and extracellular fluid, as well as fat mass, fat free mass, and percent body fat.






Our lab is one of few labs that specialize in the use of ultrasound for measurement of body composition. We utilize both A-mode (Bodymetrix, Intelametrix) and B-Mode (nexGen, Logiq-e, GE) units to measure body fat, lean mass, and visceral fat. Both methods are portable and have been validated in our laboratory. 







Using near-infared technology and AI, 3D body scanning is new technology to evaluate body composition and anthropometrics.
