Measuring Body Fat on Different Machines
Edited
The DEXA scan and BOD POD test are considered the most accurate means of measuring body composition, however results can still vary slightly from machine to machine, and from calibration to calibration. To best compare results when retesting:
Retest on the same machine at the same location
Mimic the circumstances each time you test, such as the time of day, clothing, etc.
Look for changes to your Percentile, rather than body fat percentage
