Booking questions
Before you pick a slot.
DexaFit Ponte Vedra is at Sawgrass Village, 13000 Sawgrass Village Circle, Building 5, Suite 27, Ponte Vedra Beach, FL 32082. DexaFit Jacksonville is in the Southpoint business corridor off JTB and I-95, at 6817 Southpoint Parkway, Suite 2004, Jacksonville, FL 32216. Both run the same core tests, so pick whichever is closer with the location selector at the top of the booking section.
The DEXA body composition scan, the VO₂ Max test, and the RMR metabolism test run at both locations. Book any one on its own, or combine two or three in a single visit from the bundles in the scheduler.
Yes. Both schedulers have a Two Together section for two people tested in the same appointment, with 2-person options for a DEXA scan and for test combinations.
Yes. A DEXA scan uses a very low dose of X-ray, well below a standard chest X-ray and on par with a few hours of the background radiation you take in every day. The technology has served hospitals and research labs for decades and is considered safe for most healthy adults.
The DEXA scan itself runs about 8 minutes; with check-in and a walk-through of your results, plan on roughly 20 minutes. A VO₂ Max test takes about 15 minutes to run, or about 35 minutes start to finish. The RMR test also runs about 15 minutes, or around 25 minutes in total. Book all three in one visit and you are usually done in about 75 minutes.
Instantly. Your results are ready the same visit, and a specialist reviews every number with you before you leave, so you walk out knowing what it means and the next move.
It depends on the test. For a DEXA scan, hold off on food for about 2 hours. For a VO₂ Max test, allow about 3 hours. For an RMR test, plan for about 5 hours without food. Water is fine throughout.
Start with the DEXA scan. It shows whether the weight you are losing is fat or muscle, which the scale cannot tell you. Roughly 1 in 3 pounds lost on GLP-1 therapy is lean mass, and a DEXA scan tells you whether that pattern applies to you. Adding RMR rounds out the full metabolic view.
Yes, and we encourage it. DexaFit reports use the same clinical technology and terminology physicians already know. Many clients bring their numbers to a GP, endocrinologist, sports medicine doctor, or dietitian, and the data drops straight into that conversation.
