How Accurate Is a DEXA Scan?

DEXA is considered one of the gold standards for body composition testing.


Compared to methods like:

  • BMI
  • bioelectrical impedance (InBody scales)
  • calipers
  • handheld body fat devices


DEXA scans provide significantly more detailed and consistent data.


The key advantage is repeatability. When testing conditions are kept consistent, DEXA scans are excellent for tracking trends and monitoring changes over time.


That’s why DEXA is commonly used by:

  • professional athletes
  • researchers
  • physicians
  • fitness professionals
  • military performance programs
