InBody 380

When this test is useful

The 380 is useful when you want more context than fat and muscle but the location also needs to transport its analyser. Its column folds down and the handles stay with the device. Unlike the low-profile 120, it has its own touchscreen controls and stores tests by ID. Portability is a practical operating feature; the exact model and report settings determine the outputs. The key difference from the 580 is the level of detail: the 380 reports phase angle and fluid ratio for the whole body. Segmental lean and fat analysis is still available, but this does not automatically mean regional phase angles.

What the results tell you

Fat in kilograms, body fat percentage and estimated skeletal muscle put weight changes into context. Muscle quantity is not a strength test. If muscle function matters too, the location can add a separate InGrip handgrip test.

The ECW/TBW ratio describes the extracellular share of total body water. A detailed report may also list ICW and ECW in litres. It is not a direct answer to how much you should drink. An unusual result needs context and professional interpretation.

The whole-body phase angle at 50 kHz adds information about the body’s electrical properties. For repeat tests, use the same device and similar preparation. One number does not establish the health of every cell or measure immunity; suitable reference values depend on the person being assessed.

Arms, legs and trunk have their own lean and fat overview. Lean tissue includes water. For a recurring side-to-side difference, check posture, follow the trend and consider a movement assessment when relevant.

The manufacturer’s catalogue lists visceral fat level, BMR, mineral content and body composition indices. Fat level is not VFA in cm². BIA mineral estimates are not a bone-density examination, and calculated BMR does not replace direct energy expenditure measurement.

How the device measures

The 380 measures arm, leg and trunk impedance at three frequencies, producing fifteen impedance values. Derived muscle, fat and water quantities are a different kind of result from these electrical measurements. Whole-body phase angle is reported at 50 kHz.

Test procedure and preparation

Keep your usual fluid intake, a similar interval after meals and a similar appointment time. Avoid testing straight after exercise. Use the restroom, stand quietly and check bare-foot and hand contact. BIA is not performed with an active implant. Discuss pregnancy or other relevant medical circumstances with the location beforehand.

Limitations and influences

The manufacturer’s list does not document regional phase angles or regional ECW/TBW. Compare the 580 or 770S for those outputs. The analyser requires a steady standing posture and correct electrode grip. A client unable to stand needs a different testing arrangement. Body composition remains an estimate affected by preparation and body water. Displayed decimal places do not guarantee matching measurement precision.

Choosing a device and service

The 270S already provides whole-body phase angle. The 380 adds whole-body ECW/TBW and a different frequency set. The 580 extends fluid ratio and phase angle to individual body regions and offers a larger display. More frequencies alone do not identify the best device for your question.
