Indications for Use
The TANITA Body Composition Analyzer is indicated for use in the measurement of weight and impedance, and the estimation of body mass index (BMI), total body fat percent, total body water percent and weight, muscle mass (skeletal and smooth), physique rating, bone mass, visceral fat rating with healthy range, basal metabolic rate (BMR), daily caloric intake (DCI), metabolic age, and target body fat percent with predicted weight and fat mass, using BIA (Bioelectrical Impedance Analysis). The device is indicated for use for healthy children 5-17 years old and healthy adults with active, moderately active, to inactive lifestyles.
Device Story
The Tanita SC-331 is a body composition analyzer utilizing bioelectrical impedance analysis (BIA). The device uses a 4-electrode 'foot-to-foot' measurement system at a 50kHz frequency to measure weight and electrical impedance. Inputs include user age (5-99), height, activity level, and body type (standard/athlete). The device processes these inputs to estimate body composition parameters, including BMI, body fat percentage, total body water, muscle mass, bone mass, visceral fat rating, BMR, DCI, and metabolic age. It is intended for use by healthy individuals in clinical or consumer settings. Output is provided via a display and an integrated printer, with data transfer capabilities via RS-232C and USB. Healthcare providers or users utilize these outputs to monitor body composition trends and assess metabolic health, aiding in weight management and fitness tracking.
Clinical Evidence
No clinical data provided. Substantial equivalence is based on technological characteristics and performance comparisons to predicate devices using established BIA methodology.
Technological Characteristics
4-electrode bioelectrical impedance analysis (BIA) system; 50kHz measurement frequency; AC adapter/DC7V power; RS-232C and USB connectivity; integrated printer; weight capacity up to 600 lb/270 kg or 450 kg/1,000 lb; weight increments 0.1 lb/50g or 0.2 lb/100g.
Indications for Use
Indicated for healthy children 5-17 years old and healthy adults with active, moderately active, or inactive lifestyles for measurement of weight/impedance and estimation of body composition metrics including BMI, body fat, body water, muscle mass, bone mass, visceral fat, BMR, DCI, and metabolic age.
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.
