Here's an analysis of the provided text regarding the Quantia Beta-2 Microglobulin device, presented according to your requested structure:
1. Table of Acceptance Criteria and Reported Device Performance
The FDA 510(k) summary for the Quantia Beta-2 Microglobulin doesn't explicitly state "acceptance criteria" in a typical numerical pass/fail format. Instead, it demonstrates substantial equivalence to a predicate device through various performance characteristics. The table below outlines these performance metrics and the reported results. The implication is that these results were considered acceptable for demonstrating substantial equivalence.
Performance Metric | Acceptance Criteria (Implied) | Reported Device Performance |
---|---|---|
Method Comparison (Urine Samples) | Strong correlation and reasonable agreement with predicate device | Slope: 1.088 |
Correlation Coefficient (r): 0.9894 (Quantia Beta-2 Microglobulin vs. predicate device over 110 urine samples with B2M levels 0.01 to 18.85 mg/L) | ||
Within-Run Precision (Urine Samples) | Low Coefficient of Variation (CV) | CV: |
4.2% (at mean 0.066 mg/L) | ||
1.7% (at mean 0.094 mg/L) | ||
1.5% (at mean 0.204 mg/L) | ||
1.6% (at mean 0.302 mg/L) | ||

2. Sample Size and Data Provenance for the Test Set
- Sample Size for Test Set: 110 urine samples were used for the method comparison study.
- Data Provenance: The document does not specify the country of origin for the data or whether it was retrospective or prospective.
3. Number and Qualifications of Experts for Ground Truth
- This information is not provided in the document. The study involves a method comparison against a predicate device, which itself is an already cleared diagnostic for measuring a biochemical marker, Beta-2 Microglobulin. The "ground truth" here is the measurement by the predicate device, not typically established by human experts in this context.
4. Adjudication Method for the Test Set
- This information is not applicable/provided. Adjudication is typically associated with studies where human interpretation or consensus is required to establish ground truth or resolve discrepancies, such as in image analysis or clinical diagnosis studies. For a quantitative assay comparing against a predicate, discrepancies are resolved through analytical comparison statistics.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- No, a MRMC comparative effectiveness study was not done. This type of study is more relevant for diagnostic devices that involve human interpretation (e.g., radiologists reading images) where the AI assists the human, and the effect size would relate to the improvement in human performance with AI assistance. The Quantia Beta-2 Microglobulin is an in-vitro diagnostic assay for quantitative biochemical measurement, not an AI-assisted interpretation tool for human readers.
6. Standalone (Algorithm Only) Performance Study
- Yes, in essence, the described performance studies are for the standalone performance of the Quantia Beta-2 Microglobulin assay. It measures the Beta-2 Microglobulin concentration without human intervention influencing the measurement result itself (though a human performs the test). The results for method comparison, precision, linear range, and interference are all measures of the device's standalone analytical performance.
7. Type of Ground Truth Used
- The "ground truth" used for the method comparison study was the measurement result obtained from the predicate device, the IL Test Beta-2-Microglobulin, on the same samples. For precision, linear range, and interference studies, the ground truth is derived from established analytical methods and reference values.
8. Sample Size for the Training Set
- This information is not provided or applicable in the traditional sense of a "training set" for machine learning algorithms. The Quantia Beta-2 Microglobulin is a reagent-based immunoturbidimetric assay, not a machine learning model that requires a labeled training set in the same way. Its development would involve analytical characterization and optimization using various samples, but not a distinct "training set" as understood in AI/ML contexts.
9. How the Ground Truth for the Training Set Was Established
- As noted above, a "training set" in the context of machine learning is not directly applicable here. The development and optimization of such a diagnostic assay would typically involve using samples with known analyte concentrations (established through reference methods or other validated assays) to calibrate the assay, determine reaction kinetics, and establish performance characteristics. This is part of the assay's analytical development process rather than establishing a "ground truth" for a training set in an AI/ML context.

This document is a 510(k) summary for the KAMIYA RF Control Set, an in vitro diagnostic device used to monitor the performance of RF immunoturbidimetric assays. The submission focuses on demonstrating substantial equivalence to a predicate device rather than a comprehensive, de novo clinical study with detailed acceptance criteria and performance metrics typically associated with AI/ML devices. Therefore, a direct mapping to all requested fields for AI/ML device studies is not possible.
Here's an analysis based on the provided text, addressing the relevant points and noting where direct information is unavailable due to the nature of this submission:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Stated or Implied) | Reported Device Performance |
---|---|
Substantial equivalence to predicate device (Sigma Immunology Control, K851202) | Exhibits similar "within run and between day precision and reaction characteristics for the analyte" as the predicate device. |
Consistency as a test sample of known concentration | The device is described as "a consistent test sample of known concentration." Specific quantitative data on consistency is not provided beyond the precision and reaction characteristics. |
Traceability of assigned RF values | Assigned RF values are traceable to the WHO International Reference Preparation of Rheumatoid Arthritis Serum. |
Stability | Stable for at least 1 year (unopened) and 2 weeks (after reconstitution). |
Negative for HBsAg, HCV, and HIV antibodies in human serum | Human serum used is tested and found negative for these analytes. |
2. Sample size used for the test set and the data provenance
The document does not specify a distinct "test set" sample size in the context of a traditional clinical study with patient samples. The evaluation is based on the performance of the control material itself in laboratory settings.
- Sample Size: Not explicitly stated for testing precision or reaction characteristics.
- Data Provenance: Not explicitly stated, however, the product is from KAMIYA BIOMEDICAL COMPANY in Seattle, WA, USA. The testing would have been conducted internally as part of the validation for the 510(k) submission. This is a retrospective evaluation against an existing predicate device rather than a prospective study on patient data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable in this context. The "ground truth" for a control material is its assigned value and its performance characteristics (precision, linearity, etc.) when tested against a reference method or predicate device. This isn't a diagnostic device requiring expert interpretation of results on patient samples to establish ground truth.
4. Adjudication method for the test set
Not applicable. There is no "adjudication" in the sense of resolving discrepancies in expert interpretations of patient data. The evaluation is based on laboratory measurements against a predicate device.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This is not an AI/ML device.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an AI/ML device.
7. The type of ground truth used
The "ground truth" for the KAMIYA RF Control is its assigned RF values, traceable to the WHO International Reference Preparation of Rheumatoid Arthritis Serum, and its demonstrated precision and reaction characteristics in comparison to the predicate device.
8. The sample size for the training set
Not applicable. This is not an AI/ML device, so there is no "training set."
9. How the ground truth for the training set was established
Not applicable. As there is no training set for an AI/ML algorithm, this question is not relevant.
