Intended Use

The device is a noninvasive bioimpedance meter used to estimate body fat percentage in the home setting. The device is for normal, healthy people only, and the applicable age range is 10 to 80 years old.

The device is to be used in a home environment having normal temperature and humidity conditions.

Device Description

HEALTH & LIFE HL 188 & HL 189 BODY FAT METER is a hand-held, non-sterile, reusable Body Fat Analyzer intended for estimation of the body fat of percentage in the home.

AI/ML Overview

Here's a breakdown of the acceptance criteria and study information for the HEALTH & LIFE HL 188 & HL 189 BODY FAT METER, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The provided text does not explicitly state numerical acceptance criteria with pass/fail thresholds. Instead, it indicates the device's performance was validated through a comparison study and conformity to standards.

Acceptance Criteria CategorySpecific Criteria (Implicit/Explicit)Reported Device Performance
Safety & EMCConformity to applicable standards.The device conforms to applicable standards including IEC 60601-1 and IEC 60601-1-2 requirements.
Clinical RepeatabilityStatistically and clinically acceptable repeatability across groups."The comparison study demonstrated that the clinical repeatability of HEALTH & LIFE HL 188 & HL 189 BODY FAT METER is statistically and clinically acceptable in all age/weight/height groups."
Equivalence to PredicatesNo new questions of safety or effectiveness compared to predicates."Bench testing contained in this submission and clinical testing supplied demonstrate that any differences in their technological characteristics do not raise and new questions of safety or effectiveness. Thus, the HEALTH & HL 188 & HL 189 BODY FAT METER is substantially equivalent to the predicate devices."

2. Sample Size Used for the Test Set and Data Provenance

  • Sample Size: The text states, "Subjects were grouped as male/female, ages." It does not provide a specific number for the sample size.
  • Data Provenance: Not explicitly stated (e.g., country of origin). The study appears to be clinical. It does not specify if it was retrospective or prospective, but clinical comparison studies are generally prospective.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This information is not provided in the text. The ground truth was established by comparing to DEXA technology, but details on human experts involved are absent.

4. Adjudication Method for the Test Set

This information is not provided in the text.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size

  • MRMC Study: No, an MRMC comparative effectiveness study was not explicitly mentioned. The study described is a comparison with DEXA technology to validate the device's performance, not a human reader study with or without AI assistance.
  • Effect Size: Not applicable, as an MRMC study was not performed.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Yes, the described "comparison study with device that use DEXA(Dual energy X-ray absorptiometry) technology" is essentially a standalone performance evaluation of the HL 188 & HL 189 Body Fat Meter against a reference standard. The text focuses on the device's direct measurement capabilities.

7. The Type of Ground Truth Used

The ground truth was established using DEXA (Dual energy X-ray absorptiometry) technology. DEXA is considered a highly accurate and reliable method for body composition analysis, often used as a reference standard.

8. The Sample Size for the Training Set

This information is not provided in the text. The device is a "Body Fat Meter" which implies it's a measuring device rather than an AI/ML algorithm that requires a separate training set. The comparison study described is for validation.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as a separate training set for an AI/ML algorithm is not described for this type of device. The device directly measures bioimpedance to estimate body fat percentage. The validation study used DEXA as the ground truth for performance comparison.
