AI/ML Overview

Here's an analysis of the provided 510(k) summary regarding the VITROS Chemistry Products VANC assay and controls:

1. Acceptance Criteria and Reported Device Performance

The submission uses substantial equivalence to a predicate device as its basis for clearance, rather than defining explicit acceptance criteria with pre-specified thresholds for performance metrics. The primary "acceptance criteria" here are implied by the performance of the predicate device and the demonstration of equivalent performance for the new device.

PrecisionPerformance comparable to predicateStudies performed, details not provided in summary
Expected ValuesPerformance comparable to predicateStudies performed, details not provided in summary
LinearityPerformance comparable to predicateStudies performed, details not provided in summary
SpecificityPerformance comparable to predicateStudies performed, details not provided in summary

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

The provided summary mentions "patient samples" were used for correlation studies but does not specify the sample size for the test set used to compare the VITROS VANC assay against the predicate device.
The data provenance is not explicitly stated (e.g., country of origin, retrospective or prospective), but it's implied to be retrospective as patient samples were used for correlation against an existing, cleared assay.

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

This information is not applicable as the device is an in vitro diagnostic (IVD) assay for quantitative measurement. Ground truth for quantitative diagnostic assays typically refers to a reference method or a predicate device comparison rather than expert adjudication of images or clinical assessments.

4. Adjudication Method for the Test Set

This information is not applicable for this type of IVD assay. Adjudication methods like 2+1 or 3+1 are used for subjective interpretations (e.g., imaging studies) where human experts determine ground truth. For a quantitative assay, the comparison is against an established reference method or predicate device.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

A MRMC comparative effectiveness study was not conducted and is not applicable for this device. This type of study involves human readers interpreting cases with and without AI assistance, which is irrelevant for a standalone quantitative IVD assay.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

Yes, a standalone performance study was done. The entire evaluation described is a standalone performance study, as it assesses the algorithm (the VITROS VANC assay) directly against a predicate device and other performance characteristics (precision, linearity, specificity) without human-in-the-loop interpretation. The performance metrics reported (correlation coefficient, linear regression) are direct measures of the assay's agreement with the predicate.

7. Type of Ground Truth Used

The ground truth for the comparison was established using a predicate device (SYVA Emit 2000 Vancomycin Assay) and patient samples. This means the new device's measurements were compared against the measurements obtained from an already FDA-cleared, commercially available assay using the same patient samples.

8. Sample Size for the Training Set

The document does not provide information regarding a specific "training set" sample size. For an IVD assay, the development process might involve numerous samples for calibration development and optimization, but these are typically not referred to as a distinct "training set" in the same way as machine learning models. The correlation and performance studies act as the validation.

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

Since a specific "training set" and its ground truth establishment mechanism are not detailed in the provided summary, this information is not available. However, for a chemical assay, the "ground truth" during development (analogous to training) would involve:

  • Using known concentration standards to develop calibration curves.
  • Testing against reference materials with established vancomycin concentrations.
  • Optimization of reagent formulations to achieve desired analytical performance.

The relationship between the VITROS VANC assay and the predicate device. determined by least squares linear regression, is:

VITROS VANC assay = 1.00 X + 0.00 µg/mL, with a correlation coefficient of 0.996, where X is the predicate device.

In addition to the correlation studies, studies were performed to determine the precision, expected values, linearity, and specificity of the VITROS VANC assay, (refer to the VITROS Chemistry Products VANC Reagent Instructions for Use for summaries of the results of these studies).
