The provided 510(k) summary for Eurotrol B.V. GAS-ISE Metabolites and epoc Calibration Verification Fluids does not include detailed acceptance criteria or a specific study proving the device meets acceptance criteria in the manner typically seen for diagnostic algorithms. Instead, it focuses on substantial equivalence to a predicate device and the traceability of its reference materials.

Here's an breakdown of the information that is available and a note on what is not:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state acceptance criteria or device performance in quantifiable metrics (e.g., sensitivity, specificity, accuracy, precision ranges for device vs. ground truth). Instead, it describes the intended use of the devices as "to verify the precision and accuracy of the epoc® Blood Analysis System" by providing assayed blood gas, electrolyte, and metabolite material.

The performance described is primarily related to the traceability of the analytes to recognized reference materials, which serves as an indirect form of performance validation for calibration verification fluids.

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

The document does not specify a "test set" in the context of evaluating an AI or diagnostic algorithm's performance on patient data. These devices are calibration verification fluids. For value assignment, the document states: "Multiple replicates of test samples are measured at the beginning and end of the production run on various analyzers for metabolites and on blood gas analyzers for blood gas and pH values." It also mentions "randomly selected samples from each lot."

• Sample Size: Not explicitly stated as a number of "samples" or "replicates" for verification, but implies multiple measurements for "value assignment."
• Data Provenance: Not applicable in the context of patient data. The provenance for the reference materials is stated as NIST (National Institute of Standards and Technology) and specific commercial products (Biomed DuoCal, Precipath U plus, Precinorm U plus). The study involves manufacturing and testing of the control fluids themselves.

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

This information is not applicable. The "ground truth" for these calibration fluids is established through traceability to certified reference materials (NIST SRMs), not by human expert consensus on clinical data. The value assignment process involves analytical measurements.

4. Adjudication Method for the Test Set

Not applicable, as this is not a diagnostic algorithm evaluated on clinical cases requiring expert adjudication. The "value assignment" is based on instrumental measurements and takes the "mean of multiple determinations."

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

No, an MRMC comparative effectiveness study was not done. These are calibration materials, not an AI or diagnostic device that assists human readers.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

This is not applicable as the device is a control material, not an algorithm. Its performance is intrinsic to its chemical composition and its ability to provide stable, accurate values when measured by an analytical system.

7. The Type of Ground Truth Used

The ground truth for the analytes in the Eurotrol GAS-ISE Metabolites and epoc Calibration Verification Fluids is established through traceability to internationally recognized and certified reference materials (e.g., NIST Standard Reference Materials) and other commercial reference materials. This ensures the accuracy of the assigned values.

8. The Sample Size for the Training Set

Not applicable. These are calibration materials, not an AI algorithm that requires a "training set" of data.

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

Not applicable. There is no "training set" in the context of this device. The ground truth for the product's assigned values is established through metrological traceability to reference standards (as listed under point 1).
