How it measures

BIA measures electrical impedance. A model uses this to estimate body composition, including fat and fat-free mass. InBody is a BIA brand, not a separate method. Fluid status can influence the result.

Benefits

  • Compare the documented model specifications before choosing a provider.

What the device does not tell you

  • Fat-free mass is not pure muscle mass. A single result is not a diagnosis. Different devices and similarly named metrics may use definitions that are not interchangeable.

Compare devices

For tracking change, ask about using the same device and procedure and having the results explained. For clinical examination, confirm referral and booking requirements with the provider. Differences between methods are not automatically changes in your body.

Preparation and comparability

Follow the specific device manual and provider instructions. For repeat BIA, keep time of day and food, activity and fluid conditions similar. Ask the provider about suitability and safety, especially during pregnancy or with implanted electronic devices.

What to check before choosing

A newer generation alone does not determine the value of your visit. Ask about the actual reports and consultation; when switching from the original 770, treat your first 770S test as a new baseline.

Exact-model history

The Korean manufacturer’s annual report records the 770S launch in August 2024 alongside the 970S and BWA2.0S. This is the S generation, distinct from the original 2014 model. The Czech launch date is not established.
