Intended 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 and segmental fat percent and weight, total body water percent and weight, intracellular and extracellular water weight, total body and segmental muscle mass, physique rating, bone mass, visceral fat rating with healthy range, basal metabolic rate (BMR), and fat free mass (FFM), 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. For subjects 17 years old and younger, only fat % is displayed.
Device Description
The Tanita Model MC-180MA Multi-frequency Body Composition Analyzer is a computer-operated body composition analyzer that utilizes bioelectrical impedance analysis (BIA) to estimate body composition of fat, muscle and bone, water compartments, and basal metabolic rate (BMR). Actual measurements made by the MC-180MA include body weight and bioelectrical impedance. BIA is used to make estimates based upon these measured values.
More Information

Not Found

No
The document describes a device that uses Bioelectrical Impedance Analysis (BIA) and standard calculations to estimate body composition. There is no mention of AI or ML in the intended use, device description, or performance studies. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".

No.
The device is used to measure and estimate various body composition metrics but does not provide any therapeutic intervention or treatment.

No

The device measures body composition parameters like weight, impedance, fat percentage, muscle mass, etc., and estimates BMI and BMR using Bioelectrical Impedance Analysis (BIA). While these measurements can be used by healthcare professionals as part of screening or assessment, the device itself is not described as diagnosing a disease, condition, or anomaly. Its indication is for "measurement" and "estimation" of body composition parameters, not diagnosis.

No

The device description explicitly states it is a "computer-operated body composition analyzer" that makes "actual measurements" of "body weight and bioelectrical impedance," indicating it includes hardware components for measurement.

Based on the provided information, the Tanita Body Composition Analyzer is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Tanita device function: The Tanita Body Composition Analyzer measures physical parameters like weight and bioelectrical impedance directly from the body. It then uses these measurements and algorithms to estimate body composition components. It does not analyze biological samples taken from the body.

Therefore, while it's a medical device used for health assessment, it falls outside the definition of an In Vitro Diagnostic.

segmental fat percent and weight, total body water percent and weight, intracellular and extracellular water weight, total body and segmental muscle mass, physique rating, bone mass, visceral fat rating with healthy range, basal metabolic rate (BMR), and fat free mass (FFM), 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.

For subjects 17 years old and younger, only fat % is displayed.

    1. Summary of technological characteristics compared to predicate devices:
      Both the Tanita Model MC-180MA and predicate devices (Item 3 above) are intended for use to measure weight and bioelectrical impedance, and estimate body composition (fat, muscle, bone and water) by BIA in healthy children and in healthy adults.

The technology underlying BIA estimation for the Model MC-180MA and predicate devices is the same. Design considerations-computer-operation with visual-display user interface; use of multiple-regression algorithms to predict body composition based upon body weight and segmental bioelectrical impedance measurements-and energysource considerations-multipolar surface electrodes; alternating current in the 5- to 500-kilohertz range at levels of 90 microamperes (Tanita models) to 250 microamperes (Biospace model)-are the same. Multiple-frequency measurement of bioelectrical impedence values used in estimation of percent fat, fat-free mass, total body water and extracellular water was verified in clinical testing.

Comparison of these intended-use and technological characteristics demonstrate that the Model MC-180MA is substantially equivalent to predicate devices.
