How to Measure Body Composition Accurately?

Medical-grade body composition analyzers, such as the InBody370, 570, 770, along with body composition scales like BodyPedia Body Composition Scale, offer precise measurements of body composition. However, deviations in measurement results can occur due to incorrect operation. Learn about the necessary precautions and proper operating techniques for using body composition analyzers and BodyPedia Body Composition Scale.



Stand upright for about 5 minutes before testing. Taking the test immediately after lying in bed or sitting for a long period of time might result in a slight change in the test results. This is because body water tends to move to the lower body as soon as the person stands or gets up.

Do not eat before testing. In cases where the examinee has already eaten, the test should be put off for at least two hours after the meal. This is because food mass is included in the examinee’s weight and thus, may result in measurement errors.

Use the bathroom before testing. Waste is not included in the body’s compositional elements, but the volume of urine and excrement is included in the weight measurement affecting accuracy of the test results.

Do not exercise before testing. Strenuous exercise or sharp movements can cause temporary changes in body composition. Even light exercise can change your body composition temporarily.

Take the test in the morning, if possible. Body water tends to gravitate towards the lower body throughout the day, affecting accuracy of the test results.

Thoroughly wipe the palms and soles with the wet tissue / towel before testing. Testing may be difficult if the examinee’s palms and soles are too dry or if the examinee has too many calluses.

Avoid contact with the examinee during testing. Contact may lead to interference affecting test results.


Correct Posture

The examinee must maintain proper posture to have accurate test results.
