Intended 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

The Transtek Glass Body Fat Analyzer is a home-use scale utilizing foot-to-foot Bioelectrical Impedance Analysis (BIA) to estimate body composition. The device passes a low-level 50 kHz electrical current through the user via stainless steel pads on the platform. It simultaneously calculates weight, body fat, total body water, bone mass, and muscle mass. The device stores personal data for up to 4 or 8 users and functions as a conventional scale. Users operate the device independently in a domestic setting. Output is displayed to the user to assist in monitoring health and fitness metrics.

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; power source: 2x CR2032 lithium batteries or 4x AAA batteries; 4 operating keys; home-use scale form factor.

Indications for Use

Indicated for generally healthy adults 18 years of age or older to measure weight and estimate 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.
