DXA Body Composition Analysis (Body Fat Test)

General Information | Scheduling, Insurance and Preparation | What to Expect


General information General Information

A DXA scan can determine your body fat percentage with great accuracy.

Importance of Your Body Fat Percentage

The measurement of body fat is more accurate than body mass index for assessing health. A person can have a lot of muscle, but be considered “over-weight” by many height/weight charts. The opposite can also be true – a person can have a lot of fat and little muscle and be “over-fat” but not overweight.

Too little body fat is linked to problems with normal, healthy functioning in both men and women. It can also lead to problems with reproduction in women. Too much body fat, especially when located around the abdomen, increases the risk of many diseases, including the following:

  • Type II diabetes
  • High blood pressure
  • Stroke
  • Heart disease
  • Certain cancers

For many athletes, performance is improved with optimal body composition.

By knowing your body fat percentage, and the range it falls in, you can take measures to improve your health and reduce your risk for various diseases.

The following chart shows the classification of body fat percentage ranges for each gender.

Gender Normal Overweight Obese
Adult Male
4-25%
25-30%
>30%
Adult Female
12-29%
29-35%
>35%
