InBody Technology

Why is InBody technology more expensive than other BIA devices?

InBody technology is different than that used in other BIA devices:

  • InBody technology relies on direct measurement and can measure the body segmentally.
  • InBody technology is capable of accurately measuring impedance in the trunk.
  • InBody uses multiple frequencies.
  • InBody does not use empirical estimations in calculating values.
  • InBody can evaluate a wide range of body types, from extremely obese, to elderly, to athletic.

How do InBody devices compare to other BIA devices? What are the major technical differences between the InBody and other BIA devices?

– The use of multiple frequencies to accurately measure intracellular and extracellular water.
– 8-point tactile electrode system with thumb electrodes providing a direct and reproducible measurement.
– Segmental impedance measurements to include accurate lean body mass measurements of the trunk.
– No empirical estimations required.

What are the advantages of using multiple frequencies instead of a single frequency?

Using multiple frequencies improves accuracy and precision. At a single and low frequency, it is difficult for electrical currents to penetrate the cellular membrane and assess intracellular water. As frequencies get higher, the electrical current is more capable of penetrating the cellular membrane and accurately measuring intracellular water.

How are 8-point tactile electrodes different than adhesive EKG tape electrodes?

Adhesive tape electrodes are usually placed on the wrist and a fingertip. Voltage line and current flow line always overlap from a certain point, and that point is where measurement begins.  However, it is almost impossible to place adhesive electrodes in the exact same place every time, thus the measurement starting points can differ. Rather than adhesive tape electrodes, InBody devices use tactile electrodes. Voltage line and current flow line overlap at the same point and allow for a secure and reproducible measurement starting point for each individual.

How does the InBody derive body fat measurements from body water measurements?

Body water volume is closely related to fat free body mass. When fat free mass is subtracted from total weight, body fat mass remains.

How do InBody devices work?

InBody devices use direct segmental measurement bioelectrical impedance analysis (DSM-BIA) to precisely measure body composition by sending multiple electrical currents through the body, resulting in up to six different impedance readings for the trunk and each of the four limbs.

The innovative in-depth analysis of the InBody Test yields accurate results for body composition outputs, such as body fat mass, skeletal muscle mass, (segmental) lean body mass, and percent body fat.

For more information, please read InBody Technology.

What is impedance?

Impedance is the frequency-dependent opposition of a conductor to the flow of an alternating electric current. Impedance is composed of two main properties, resistance and reactance.

InBody provides segmental impedance values at varying frequencies to allow for accurate analysis of the human body. Since reactance is the interrupting force of alternating current flow, it increases in proportion to the integrity of cell membrane. Therefore, reactance and phase angle decrease when the number of cells is low or the cell membrane is more permeable or unhealthy.

The more water there is, the lower the impedance.

Body Composition

Is BIA (Bioelectrical Impedance Analysis) accurate?

Historically, BIA technology, devices, and results have been met with some degree of skepticism. However, InBody technology addresses these concerns with its technological features and provides great precision and accuracy for total body and segmental measurements.

For more information, please read InBody Technology.

What are some other commonly used methods for body composition analysis?

Other methods of measuring body composition include DEXA, hydrostatic weighing, air displacement, and anthropometric calipers.

When measuring body composition on BIA devices, why do results change when height changes?

The volume of a cylinder, in this case the body, changes when the height of the cylinder changes. BIA devices consider the body as a cylinder and the volume of body water is calculated with the height and impedance of the body.

How can percent body fat change within a time frame as short as one day?

Weight and body water changes can occur with the introduction of meals and fluids, or with a change in environment. Circulation of body water may also cause changes in water distribution throughout the day. It is recommended that repeat tests be performed under the same testing conditions, in the same environment, and at the same time of day as the initial test.

What are the differences between InBody models?

All InBody models accurately measure weight and body composition. Other outputs and technical specifications differ by model. These differences are highlighted on the main product page.

What fields uses body composition analysis?

Body composition measurements on the InBody products are used in a variety of organizations and facilities, including:

What is the life expectancy of an InBody device?

InBody devices do not have a defined life expectancy. As long as you take good care of the device, you can continue to use your InBody device for many years. There are functioning InBody units greater than 10 years old.

What can I use to disinfect the InBody?
Wear disposable gloves and use 70% (or above) Isopropyl Alcohol Wipes to disinfect the InBody while paying special attention to the hand electrodes, footplate, screen, and any other part of the device that is frequently touched.
To prevent damage to the device:

  • Do not spray or pour liquids directly on your InBody device.
  • Do not immerse any part of the InBody device in liquid.
  • Do not use cleaning agents composed of quaternary ammonium components such as benzalkonium/benzylalkonium chloride, which may cause discoloration and corrosion.

What is the warranty policy?

The standard warranty policy is 1 year from the purchase date for all InBody products. Extended warranty is available at the time of purchase, and you may be eligible to purchase an extended warranty if the product was purchased within a year. The warranty does not cover any physical and/or cosmetic damage, which includes any type of water damage. Other fees will apply for additional services such as loaner units and expedited shipping.

How often does the InBody device need to be calibrated?

The InBody device has an auto-calibration function that is completed each time the device is turned on. It is not necessary to calibrate the InBody device unless there have been circuit board replacements. Load cell calibration should only be performed when weight measurements seem incorrect.

Problems with the device

The device keeps freezing

If the device freezes randomly on the main screen:
Try unplugging the USB cord that connects the InBody to the printer. Sometimes, garbage values can cause the InBody program to freeze. You will need to purchase a separate filter for the InBody and printer.

If the unit is freezing during the warm up process:
Please contact us for support.

The weight on my scale is off

Try turning the unit off and then back on. Do not stand, press, or leave anything on top of the base of the scale while the unit is warming up.
Go to SETUP to make sure that there is not a weight adjustment setting made to your unit.
If none of the above resolves the issue, please contact us for assistance.

How long does the InBody Test take?

The InBody Test lasts between 15 seconds and 120 seconds, depending on the model being used.

InBody 270: 15 seconds
InBody 370S: 45 seconds
InBody 570: 45 seconds
InBody 770: 60 seconds
InBody S10: 90 seconds (Medical Mode), 120 seconds (Research Mode)

Why do I need to remove my shoes and socks for the test?

Because the bottom of your feet must be in direct contact with the electrodes, clothing items such as shoes, socks, stockings or leggings must be removed for accurate results.
Watch the Precautionary Steps video to see all the steps to take to ensure accurate InBody Tests.

Can I operate an InBody device without any special training?

Yes. InBody devices are quick, convenient, and easy to use.

Each InBody model has an intuitive LCD screen for data entry and prints a result sheet automatically after each test. Each InBody comes standard with a quick set-up and installation guide, a user manual, a results interpretation poster, and a results interpretation booklet.

Why should I stand upright during the test?

The InBody requires you to stand upright because an upright position resembles the natural state of the human body.

Are there any height, weight, or age restrictions for the InBody Test?

All of the InBody models have the same test ranges for weight, height, and age.

Weight range: 10kg – 250kg
Height range: 95cm – 220cm
Age range: 3 years to 99 years

Will I feel the electrical currents during the test?

For the average population, the electrical currents sent through the body during InBody Tests are too low to feel.  However, there is a small possibility that individuals with tactile sensitivity may feel a slight sensation.

What factors can affect the accuracy of my test results?

Changes in body composition reflect body status, which may be affected by factors such as disease, nutrition, hydration, and medication. Accessories such as jewelry may interfere with the electrical conductivity. Improper posture will also affect test results.

It is recommended to maintain the same testing conditions from test to test to produce high data reproducibility and comparability.

Can the InBody test people with prosthetic limbs?

Unfortunately, the InBody’s electrical currents are unable to flow through prosthetic limbs. The electrodes must come into contact with the body at all eight contact points: thumbs, palms, soles, and heels.
The InBody S10 allows those with amputated limbs to test with the adhesive electrodes. However, the data for the amputated limbs will not be accurate, so results should be analyzed by a medical professional for accurate health consultations.

Who are not recommended to take an InBody test?

People with artificial electrical implants such as a defibrillator or pacemaker are not recommended to take an InBody Test. The electrical currents of the InBody may disrupt the functionality of life-sustaining implants.
Women who are on their menstrual cycle or are pregnant are not recommended to test as they may not obtain accurate results due to subtle changes in their hydration and body water levels.

Why use an InBody Tissue before testing?

The InBody Tissue increases electrical conductivity where the hand and feet electrodes make contact with the skin. Without the tissues, it could be difficult for the electrical currents to flow through thick calluses or hard skin on the hands or bottom of the feet.
