Body fat composition measurement gold standard compliance

Underwater Weighing is known as the “Gold Standard” of body fat measurement. Many people refer to it as the “dunk test.” All other methods, including our Futrex ® 6100XL Body Composition Analysis System, are calibrated to to this “reference laboratory. Underwater Weighing has a margin of error of plus / minus 3%. The Futrex ® System has the same margin of error precision as underwater weighing.

How single site body fat measurement works

Futrex ® is the only gold standard method of measuring body fat that uses completely safe, near-Infrared light to directly measure percent body fat. Extensive U.S. Government research determined that the midpoint of the biceps has a direct correlation with the body’s overall fat level.

Body Composition Analysis on Arm

During measurement, the Futrex ® 6100XL Body Composition Analysis System sends a safe, near-Infrared light beam into the triceps at specific wavelengths that fat will absorb and lean mass will reflect. The light absorption is measured to determine body fat -- it’s that simple!

Body fat test results which are equivalent to underwater weighing are instantly displayed for you.
