Intended Use

The Transtek Glass Body Analyzer measure weight and uses bioelectrical impedance analysis (BIA) technology to estimate body fat, total body water percentage, bone mass, and muscle mass in generally healthy adults 18 years of age or older. It is intended for use in the home/domestic setting only.

Device Story

Transtek Glass Body Analyzer (models GBF-830, GBF-835, GBF-950, SA-15) uses foot-to-foot bioelectrical impedance analysis (BIA) to estimate body composition. Device inputs: electrical current (50 kHz) passed through body via glass and stainless steel pads on platform. Device outputs: weight, body fat mass, total body water, bone mass, muscle mass. Used in home/domestic setting by adults 18+; operator is the user. Data stored for 8-10 users. Device also functions as conventional scale. Output displayed to user for health/fitness monitoring.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

BIA technology; 50 kHz operating frequency; 4 electrodes; glass and stainless steel contact pads; battery-powered (AAA, AA, or CR2032 depending on model); standalone operation; stores data for 8-10 users.

Indications for Use

Indicated for generally healthy adults 18 years of age or older for measurement of weight and estimation of body fat, total body water percentage, bone mass, and muscle mass. Contraindicated for individuals with pacemakers or other internal medical devices.

Regulatory Classification

Identification

An impedance plethysmograph is a device used to estimate peripheral blood flow by measuring electrical impedance changes in a region of the body such as the arms and legs.

Special Controls

*Classification.* Class II (special controls). The device, when it is a body composition analyzer which is not intended to diagnose or treat any medical condition, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

Predicate Devices

• Scaleman Body Fat Scales, Model FS-148BW1 (K083838)

mass. The electrical current is small and may not be felt. Contact with the body is made via glass and stainless steel pads on the platform of the analyzer.

This method simultaneously calculates your personal weight, body fat, total body water, bone mass and muscle mass, giving you a more accurate reading of your overall health and fitness.

This scale stores the personal data of up to 8 or 10 users. As well as being an analyzer, this device can be used as a conventional scale.

#### 6. Intended Use of Device

The Transtek Glass Body Analyzer measure weight and uses bioelectrical impedance analysis (BIA) technology to estimate body fat, total body water percentage, bone mass, and muscle mass in generally healthy adults 18 years of age or older. It is intended for use in the home/domestic setting only.

## 8. Conclusions

The subject devices have all features of the predicate device, Scaleman Body Fat Scales (Model FS-148BW1) except the new features and the power source voltage of the device. These differences do not affect the safety and effectiveness of the subject devices : BIA (Bioelectrical Impedance Analysis) technology is same as what is used in Scaleman Body Fat Scales (Model FS-148BW1). Thus, the subject devices are substantially

equivalent to the predicate devices.
