DXA: Any thin, comfortable clothing without any metal zippers, snaps, or buttons is acceptable. For females, we recommend wearing any type of bra without underwire, such as a sports bra.

Am I allowed to exercise on the day of, or prior to testing?

In general, we recommend that you abstain from vigorous exercise for 12-24 hours prior to testing.

How long must I wait after eating or drinking before testing?

If doing an RMR test, we recommend doing the test in the morning off an overnight fast (water is fine). Also avoid caffeine on the day of any body composition assessment or RMR assessment. 

What is the difference between total fat mass, total fat-free mass, and percent body fat?

Fat mass is the absolute amount of body fat, measured in pounds or kilograms. Fat-free mass or lean mass is any tissue or part of the body that does not contain fat, such as skeletal muscle, bones, and water. Body fat percentage is a ratio of total weight of fat to the total weight of the body.

Do you offer any packages or discounts for multiple assessments?

Yes, if you wish to purchase multiple assessments at once you will receive a 20% discount for every test purchased after the first. We also offer packages for multiple DXA scans. You must pay up front and you will receive a voucher for any test you wish to do at a later date, valid up to one year. This option is great if you are beginning a diet or fitness routine and would like to compare "before" and "after" information.
