Testing on the InBody

Testing on the InBody

How long does it take to perform a test?

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

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.

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’s manual, a results interpretation poster, and a results interpretation booklet.

If you have any questions regarding the InBody, please contact an InBody specialist or Customer Service representativehere.

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.

What are important guidelines users should or should not do before a test?

Before a test, you should:

• Use the bathroom
• Maintain the same testing conditions as your first test
• Use an InBody tissue to wipe down electrodes
• Avoid eating or wait two hours after a meal

Avoid testing if before the test, you:

• Exercised strenuously
• Used a sauna, steam room, or bath
• Consumed diuretics such as caffeine, alcohol, and medication
• Have a fever, cold, or chill

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: 10 – 250kg
• Height range: 95 – 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 an 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.

Who are not recommended to take an InBody test?

• People with artificial electrical implants such as a defibrillator or pacemaker should not be tested. The electrical currents of the InBody may disrupt the functionality of life-sustaining implants.
• Women who are on their menstrual cycle may not obtain accurate results due to subtle changes in their hydration and body water levels.
• Pregnant women are not recommended to take the test because of the body’s constant fluctuations during pregnancy.

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. The InBody Tissue also serves as an antibacterial wipe, which helps with the sanitation.

Does the InBody do wireless printing?

Currently, the InBody units do not have wireless printing capabilities. The InBody 270, 570, and 770 connect to Lookin’Body Web, a cloud database management software that allows you to look at your result sheets on the computer and email them to clients in PDF format.

InBody Technology

Why is InBody technology more expensive than other BIA devices?

InBody technology is patented and is different than that used in other BIA devices. InBody technology relies on direct measurement and can measure the body in a segmental fashion; is capable of accurately measuring impedance in the trunk region; uses multiple frequencies and does not need to use statistical (or empirical) data in calculating values; and evaluates 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 patented 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. No population-based statistical data is used in calculating results.

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

Using multiple frequencies improves accuracy and precision. At a single, 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.

What printers are compatible with InBody devices?

Almost all printers using PCL3 or above are compatible with InBody devices. However, InBody units are sold with a standard configuration that includes a compatible printer. Download the list of compatible printers in our download centerhere.

How do InBody devices work?

InBody devices use direct segmental measurement bioelectrical impedance analysis (DSM-BIA), a patented technology, 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.

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.

General Body Composition

Is BIA technology 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 regional measurements.

What other commonly used methods for body composition analyses exist?

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

How often can you measure body composition?

The frequency of measurement is fully dependent on each facility and program. InBody recommends testing every 2-4 weeks.

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.

Can anyone purchase an InBody device?

Yes. The InBody 270, 370, 570 and 770 are non-prescriptive, over-the-counter medical-grade devices and can be purchased by any individual or organization.

What fields uses body composition analysis?

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.

How often does the InBody need to be serviced?

The InBody does not require any regular servicing. However, if the unit is turned on all the time, it is a good idea to restart the unit once every 2 weeks to 1 month.

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 clean the InBody?

Do not use any materials that contain acids as this may corrode the conductive surface on the electrodes. You may also use a 70% isopropyl alcohol solution to clean the unit, however do not leave loose liquids on or around the elecrodes as this could cause damage.

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.

What type of warranty is included with the InBody device?

Each InBody device comes with a standard manufacturer’s 1-year warranty that covers parts, labor, and one-way shipping.

How do I recalibrate the InBody?

While the InBody does not require a calibration unless it has been serviced, the InBody always performs a weight calibration during warm up.
