98.4% correlation with DEXA. 100% reproducibility. Validated in 6,000+ published clinical studies. Here is the evidence.
InBody vs DEXA — Full Comparison →Not all BIA (Bioelectrical Impedance Analysis) is equal. InBody's patented DSM-BIA technology eliminates the three main sources of error found in conventional BIA devices.
Standard BIA devices measure the whole body as a single path and estimate segmental composition. InBody measures each segment (right arm, left arm, right leg, left leg, trunk) directly and independently. This eliminates the estimation error that affects whole-body single-path devices — especially important for detecting muscle imbalances and regional fat distribution.
InBody uses multiple frequencies (from 1kHz to 3MHz depending on model) to separately measure intracellular water and extracellular water. Low frequencies measure extracellular water only. High frequencies penetrate cells and measure total body water. This separation enables accurate fat mass, muscle mass, and body water analysis that single-frequency BIA simply cannot provide.
Most BIA devices apply population-based prediction equations (derived from a reference group) to estimate body composition. InBody uses only the raw impedance measurements from the 8-electrode 4-limb contact — no age, gender, or ethnicity-based correction formulas are applied. This eliminates demographic bias and makes InBody accurate across diverse populations, including South Asian subjects.
How does InBody compare to other body composition measurement methods?
| Method | Accuracy | Radiation | Scan time | Measures visceral fat | Cost |
|---|---|---|---|---|---|
| DEXA Scan | Gold standard (100%) | Yes | 20–40 min | Yes | High (hospital) |
| InBody (DSM-BIA) | 98.4% vs DEXA | None | 60 seconds | Yes | Low (per test) |
| Standard BIA (home scales) | 70–80% estimated | None | 30 seconds | No | Very low |
| BMI | Not applicable | None | Instant | No | Free |
| Hydrostatic weighing | ~95% | None | 30–60 min | No | High (specialist) |
InBody accuracy has been validated across a wide range of clinical and research applications.
Validated for tracking fat loss vs muscle preservation post-surgery. Used in leading bariatric centres across India.
Phase angle measurement validated as a prognostic marker. Used in cancer nutrition and sarcopenia screening.
Segmental muscle analysis validated for athlete monitoring, muscle imbalance detection and performance tracking.
Visceral fat and ECW/TBW ratio validated as markers for insulin resistance and metabolic syndrome.
ECW/TBW ratio validated for fluid overload monitoring in dialysis patients. Phase angle as nutrition marker.
Age-specific validation for children and adolescents. Safe for paediatric body composition monitoring.
InBody achieves 98.4% correlation with DEXA scan — the gold standard. Unlike DEXA, InBody uses no radiation, takes 60 seconds, and costs a fraction of the price per test.
Significantly more accurate. Home scales use single-frequency BIA with population-based estimation formulas — prone to large errors (±5-10% body fat). InBody uses multi-frequency direct segmental measurement with no estimation equations. Validated accuracy vs single-frequency BIA is substantially better.
100% reproducible under identical conditions. This is why InBody is used for longitudinal tracking — you can trust that changes in your result reflect actual body composition changes, not measurement noise.
Yes. InBody applies no demographic correction equations — results are based purely on impedance measurements. Studies with South Asian populations confirm InBody's accuracy. Its visceral fat measurement is especially relevant for Indian adults who tend to accumulate more visceral fat at lower BMI.
Yes. InBody is used in clinical settings by hospitals, oncology centres, nephrology departments and bariatric surgery programmes across India and globally. 6,000+ peer-reviewed studies have used InBody as their measurement tool.
