You can get a body composition analysis at most gyms, university wellness centers, hospitals, dietitian offices, and specialized health clinics. The type of test available depends on the location, and prices range from free (included with a gym membership) to several hundred dollars for clinical-grade scans. Where you go should depend on why you want the test and how precise you need the results to be.
Gyms and Fitness Centers
This is the most accessible option for most people. Many commercial gyms offer body composition testing as part of a membership package or for a small fee, typically $15 to $50. The technology varies. Some gyms use handheld or scale-style devices that send a weak electrical current through your body to estimate fat, muscle, and water. This method, called bioelectrical impedance analysis (BIA), is quick and painless but can be thrown off by hydration levels, recent exercise, or even a large meal.
Higher-end fitness studios and personal training facilities sometimes invest in more advanced BIA machines, like the InBody or Tanita professional models, which use multiple contact points and tend to be more consistent than consumer-grade scales. These typically cost $25 to $75 per scan. Many trainers offer a free initial scan as part of an onboarding session, then use follow-up scans to track progress over time. If you’re primarily interested in seeing trends rather than exact numbers, a gym-based scan repeated under the same conditions (same time of day, similar hydration) works well.
Universities and Research Facilities
University kinesiology, exercise science, and nutrition departments frequently offer body composition testing to the public, often at reduced rates because they use the sessions for student training. These facilities sometimes have access to methods you won’t find at a typical gym, including hydrostatic (underwater) weighing and air displacement plethysmography, commonly known by the brand name Bod Pod.
Hydrostatic weighing involves being submerged in a water tank while your body density is calculated. It has long been considered a gold-standard method, though it’s somewhat uncomfortable and requires you to exhale fully while underwater. The Bod Pod achieves similar accuracy by measuring air displacement inside an egg-shaped chamber. It takes about five minutes and doesn’t require getting wet. University-based tests generally cost $25 to $75, and some labs run periodic community testing events at even lower prices. A quick search for your nearest university’s exercise science department will usually turn up scheduling information.
Medical Clinics and Hospitals
For the highest precision, a DEXA scan (dual-energy X-ray absorptiometry) is the current clinical gold standard. Originally designed to measure bone density, DEXA also provides a detailed breakdown of fat mass, lean mass, and bone mineral content for each region of your body. You’ll lie on a table for about 10 to 15 minutes while a low-dose X-ray arm passes over you. The radiation exposure is minimal, roughly equivalent to a day of natural background radiation.
Hospitals, radiology centers, and some endocrinology or sports medicine clinics offer DEXA scans. The cost without insurance ranges from $75 to $300 depending on your area. Insurance rarely covers the scan when it’s ordered purely for body composition purposes, though it may be covered if your doctor orders it for bone density screening (common for postmenopausal women or people at risk of osteoporosis). If you’re already getting a bone density scan, ask whether the facility can run the full body composition report at the same time.
Dedicated Body Composition Studios
A newer category of business has emerged in many cities: standalone studios that specialize entirely in body composition scanning. Companies like DexaFit, Body Spec, and similar regional brands offer DEXA, Bod Pod, and metabolic testing under one roof. These tend to cost $40 to $150 per scan, with package discounts if you plan to retest every few months. The advantage is convenience and consistency. Staff are trained specifically in body composition protocols, and the environment is standardized, which helps when comparing results over time.
These studios are most common in larger metro areas. A search for “DEXA scan near me” or “body composition scan” plus your city will usually surface options if they exist in your area.
Dietitian and Nutritionist Offices
Registered dietitians, particularly those working in sports nutrition or weight management, often keep a professional-grade BIA device in their office. The scan becomes part of a larger consultation where results are interpreted in context: your goals, your eating patterns, your activity level. This is a good option if you want more than just numbers on a printout. Expect to pay for the consultation itself ($100 to $250 for an initial session), with the body composition scan folded into that cost.
Choosing the Right Method for Your Goals
The “best” test depends on what you’re trying to learn. If you want a single, highly accurate snapshot of where you stand, a DEXA scan gives you the most detailed data, including how fat and muscle are distributed across your arms, legs, and trunk. If you’re more interested in tracking changes over weeks or months, consistency matters more than absolute accuracy. A BIA device at your gym, used under the same conditions each time, can reliably show whether you’re gaining muscle or losing fat even if the exact percentages are slightly off.
Hydrostatic weighing and the Bod Pod fall in between: more accurate than BIA, less detailed than DEXA, and generally more affordable than a clinical scan. They give you a reliable overall body fat percentage but won’t tell you which specific areas carry more fat or muscle.
One practical tip: no matter which method you choose, test conditions matter. Hydration, recent meals, exercise, and even the time of day can shift results. For the most useful data, get scanned in the morning before eating or working out, and replicate those conditions if you retest. Small fluctuations between tests are normal and don’t necessarily reflect real changes in your body composition.
Typical Costs at a Glance
- Gym BIA scan: Free to $50
- Professional BIA (InBody, standalone studio): $25 to $75
- Bod Pod: $30 to $75
- Hydrostatic weighing: $30 to $75
- DEXA scan: $75 to $300
- Dietitian consultation with scan: $100 to $250
If budget is your main concern, start with whatever your gym offers. If precision matters or you’re working with a trainer or dietitian on specific goals, investing in a DEXA or Bod Pod session gives you a more reliable baseline to work from.
