Indications for Use

The Transtek Glass Body Fat 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

Device is a body composition analyzer using Bioelectrical Impedance Analysis (BIA). It passes low-level electrical current through the body; measures resistance (impedance) of fat tissue versus muscle tissue fluids. Input: electrical impedance and weight. Output: estimated body fat, total body water, muscle mass, and bone mass. Used in home/domestic settings by patients for self-monitoring. Device includes an integrated Bluetooth module to transmit measurement data to a paired mobile terminal for display and storage. Results are also shown on the device's LCD. Data transmission allows users to track health metrics over time.

Clinical Evidence

No clinical data. Bench testing only. Performance tests, risk management, and design verification were conducted to demonstrate that the wireless modification does not affect measurement accuracy or device safety.

Technological Characteristics

BIA technology; Bluetooth module for wireless data transmission; LCD display. Conforms to ISO14971 (risk management), IEC60601-1 (electrical safety), IEC60601-1-2 (EMC), and FCC Part 15 (EMI).

Indications for Use

Indicated for generally healthy adults 18 years of age or older to estimate body fat, total body water percentage, bone mass, and muscle mass, and to measure weight. Intended for home/domestic use.

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.

Section 6 - 510(k) Summary

{1}------------------------------------------------

#### 5. Device Description

Transtek Glass Body Fat Analyzer uses BIA (Bioelectrical Impedance Analysis) technology which passes an electrical current through the body to estimate body fat mass, total body water, muscle mass and bone mass. The electrical current is low and may not be felt. The current passes freely through the fluids contained in muscle tissue, but encounters difficulty/resistance when it passes through fat tissue. This resistance of the fat tissue to the current is termed 'Bioelectrical Impedance', and is accurately measured by Glass Body Fat Analyzer LS203-B.

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

Transtek Glass Body Fat Analyzer GLS203-B embeds a Bluetooth module that allows it to connect to nearby BT receiving terminal. Once measurement is over, the LCD of device displays measurement results, and the device will start to send out measurement data to paired BT terminal at the same time. Thus users can receive, display, and storage measurement results from LS203-B unit through mobile BT terminal.

#### 6. Intended Use of Device

The TRANSTEK Glass Body Fat Analyzer measure weight and uses bioelectrical impedance analysis (BIA) technology to estimate body fat, total body water percentage, muscle mass, and bone mass in generally healthy adults 18 years of age or older.

It is intended for use in the home/domestic setting only.

#### 7. Design Control Activities and Performance Tests Summary

Design control activities for this modification were performed and bench tests have been done. Those performance tests, risk management, and design verification tests provide demonstration that the difference does not raise any new questions of safety and effectiveness.

LS203-B conforms to the following standards:

ISO14971, Risk management to medical devices

IEC60601-1, Electrical safety; IEC60601-1-2, Electromagnetic compatibility

FCC Part 15, EMI tests of FCC Radiation rules and regulations

Explanation: The wireless function does not affect body analyzer measurement function. Therefore we have not done the Clinical test.

#### 8. Summary of Substantial Equivalence

8.1 Difference between proposed devices and the predicate device

The only significant difference between the two devices is that modified device uses Bluetooth instead of RF which the original device used.

More modification details are described in this submission.

Section 6 - 510(k) Summary

{2}------------------------------------------------

#### 8.2 Discussion

Transtek Glass Body Fat Analyzer LS203-B has identical indication for use, fundamental scientific technology, dimensional specifications, and similar performance specifications, software/firmware, functions, labeling to the predicate device.

The only significant difference between LS203-B and the predicate device is that the modified device's wireless data transmission function achieved by a BT module instead of original's RF module. The Bluetooth does not raise any new questions of safety and effectiveness.

All required design control activities have been implemented and all applicable performance tests have been done according with demands of FDA regulations. We found that the modified device does not create new significant risk.

#### 9. Conclusions

Transtek Glass Body Fat Analyzer LS203-B is substantially equivalent to the predicate device LS206-E by having identical indication for use, identical fundamental scientific technologies, and similar wireless data communications that does not impact the safety and effectiveness of the device.
