    Intended Use

    The products encompassed by this request are intended for in-vitro diagnostics use and are intended for r ne products chooling and flushing the sample flow path of the equivalent OEM Analyzers. Mission reagents are intended to serve as direct replacements to like named products manufactured by the OEM. The products encompassed are to be handled using normal laboratory precautions.

    Device Description

    The Calibrators for the OEM Instruments are aqueous reagents with salts added to obtain desired analyte levels to provide calibration of the electrodes and rinse the sample path. The reagents are intended for use on equivalent OEM Instruments. The original equipment manufacturer (OEM) of the instruments and the predicate reagents which are necessary for the continued operation and use of the instruments. Mission uses a similar composition, description and packaging as that used by the OEM in its products, as shown in the packaging section of this submission.

    AI/ML Overview

    Here's a breakdown of the acceptance criteria and the study details for the Mission Diagnostic Reagents, based on the provided document.

    1. Table of Acceptance Criteria and Reported Device Performance

    The document doesn't explicitly state "acceptance criteria" in a numerical or categorical format. However, the performance is demonstrated through precision coefficent of variation (%CV) and correlation (slope and R^2) against OEM reagents. The implicit acceptance criterion for this type of device (calibrators/reagents intended as direct replacements) would be that the Mission reagents perform comparably to the OEM reagents, demonstrating "substantial equivalence."

    A reasonable interpretation of the acceptance criteria, based on the presented data, would be:

    • Precision (%CV): Low %CV values, indicating good repeatability. While no specific threshold is given, the reported values are generally very low (often < 1%, with a few instances up to ~10%) which are typical for clinical chemistry assays.
    • Correlation (Slope and R^2): Slope near 1 and R^2 near 1, indicating a strong linear relationship and good agreement between Mission and OEM reagents. This is explicitly stated in the document: "Correlations demonstrated slopes of 1 and R^2's of 0.99, which support a claim of substantial equivalence."

    Table: Acceptance Criteria (Implicit) and Reported Device Performance

    Performance MetricImplicit Acceptance CriterionReported Device Performance (Summary)
    Precision (%CV)Low %CV, comparable to established assay performance.Generally very low, ranging from 0.0% to 10.4% across various analytes and instruments. Most are < 5%.
    Correlation (Slope for Y=mX+b)Slope (m) close to 1 (indicating proportional agreement).Ranging from 0.95 to 1.04 across various analytes and instruments (for both human serum and QC results).
    Correlation (R^2 for Y=mX+b)R^2 close to 1 (indicating strong linear correlation).Ranging from 0.99 to 1.00 across various analytes and instruments (for both human serum and QC results).

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

    • Sample Sizes (Test Set):

      • Precision Studies:
        • Ciba-Corning 238: N=9 per QC level for pH, pO2, pCO2.
        • Ciba-Corning 248: N=10 per QC level for pH, pO2, pCO2.
        • Ciba-Corning 348: N=20-21 per QC level for Na, K, Ca, pH.
        • Ciba-Corning 664: N=16 per QC level for Na, K, Cl, tCO2.
        • Ciba-Corning 288: N=18-25 per QC level for Na, K, Ca, pH.
      • Correlation Studies (Regression Analysis):
        • Human Serum:
          • Na (348, 288, 664): N=19-44.
          • K (348, 288, 664): N=44-49.
          • Ca (348, 288): N=35-44.
        • QC Results:
          • pH (238, 248, 348, 288): N=21-30.
    • Data Provenance: The document does not explicitly state the country of origin. The studies appear to be retrospective in the sense that they are conducted on existing instruments and control/serum samples. However, the data collection, where Mission reagents are compared against OEM reagents on the same analyzer and same test days, indicates a controlled study design. The human serum samples are implicitly "prospective" for the correlation study, as they were "spiked with Human Serum Albumin to yield varying concentrations."

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

    This information is not applicable as the ground truth for these medical device assays (calibrators) is established by the reference values of certified control materials or reference methods, not by expert consensus.

    4. Adjudication Method for the Test Set

    This information is not applicable. Adjudication typically refers to expert review processes for subjective assessments (e.g., image interpretation). For analytical performance studies of calibrators, the "ground truth" or reference values are derived from quantitative chemical analysis or certified reference materials, not expert adjudication.

    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

    This information is not applicable. This document describes an in-vitro diagnostic (IVD) calibrator, not an AI-assisted diagnostic device or a system involving human readers.

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

    This information is not applicable. This document describes an in-vitro diagnostic (IVD) calibrator, not an algorithm or AI system. The "performance" refers to the analytical performance of the chemical reagents.

    7. The Type of Ground Truth Used

    • Precision Data: The ground truth for precision is the consistency of results obtained from the Mission reagents themselves when repeatedly measured against known control material levels. The "ground truth" or target values for the control materials (QC1, QC2, QC3) would have been established by their manufacturer.
    • Correlation Data:
      • Human Serum Samples for Na, K, Cl, Ca: The ground truth for the comparison is the results obtained using the OEM reagents on the same analyzer. The values obtained with the OEM reagents serve as the reference for determining the equivalence of the Mission reagents. These samples were also "spiked with Human Serum Albumin to yield varying concentrations," indicating prepared samples with expected values.
      • QC Samples for pH: Similar to human serum, the ground truth for comparison is the results obtained using the OEM reagents on the same analyzer for the three levels of QC.

    8. The Sample Size for the Training Set

    This information is not applicable. This device is a chemical reagent, not an AI model that requires a training set.

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

    This information is not applicable for the same reason as above.
