AI/ML Overview

The provided text is a 510(k) Summary for the Bio-Rad Architect B12 MasterCheck device. This type of submission is for in vitro diagnostic devices (IVDs), specifically controls used to verify the performance of an assay. The information requested (acceptance criteria, study details, sample sizes, ground truth, etc.) is typically found in performance studies for diagnostic assays or prognostic devices that classify or predict outcomes in patients.

For the Bio-Rad Architect B12 MasterCheck, which is a calibration verification and linearity control, the "acceptance criteria" and "device performance" are established in a different context. These devices are designed to have known concentrations of analytes, and their performance is typically evaluated by demonstrating that they produce expected results within a specified range when tested on the target analytical system (in this case, the Abbott Architect i System for B12 assay).

Therefore, many of the requested points are not directly applicable to this specific type of device or cannot be extracted from the provided 510(k) summary. I will answer the applicable questions based on the information available:


1. A table of acceptance criteria and the reported device performance

The 510(k) summary does not explicitly state specific numerical acceptance criteria or performance data for the Architect B12 MasterCheck. For a control device, performance is typically demonstrated by showing that the manufactured lots consistently yield the expected B12 concentrations when run on the Abbott Architect i System, verifying the system's sensitivity, calibration linearity, and reportable range.

The "performance" of such a device is inherently tied to its ability to control the assay it's designed for, rather than producing diagnostic results itself. The summary implies that "performance" is a comparison of its technological characteristics to a predicate device.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The summary does not describe a "test set" in the context of patient samples or a diagnostic study. This device is a control product. Performance verification would involve running multiple replicates of the control material on the Abbott Architect i System. The specific number of replicates or runs for a performance verification study is not provided. Data provenance is not available.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This is not applicable. The "ground truth" for a control material like Architect B12 MasterCheck is its manufactured, assigned concentration of B12. This concentration is established by the manufacturer (Bio-Rad Laboratories) through rigorous analytical methods and reference to recognized standards. It does not involve expert consensus in the diagnostic sense.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable, as there is no "test set" requiring adjudication in the context of diagnostic interpretation.

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 device is a laboratory control, not an AI-assisted diagnostic tool, and involves no human readers or diagnostic interpretation.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This device is an IVD control, not an algorithm or AI system.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

The "ground truth" for the Architect B12 MasterCheck is the assigned B12 concentration within each level of the control material. This is established through the manufacturer's gravimetric preparation and analytical value assignment processes, traceable to reference standards.

8. The sample size for the training set

Not applicable. This device is a control, not a machine learning algorithm that requires a training set.

9. How the ground truth for the training set was established

Not applicable for the same reason as point 8.

Dear Ms. Platt:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
