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.
|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.
