    AI/ML Overview

    The provided text describes the SYNCHRON® Systems DAT Low and High Urine Calibrators II device. It does not contain information about acceptance criteria or a study that specifically proves the device meets such criteria in terms of performance metrics like sensitivity, specificity, accuracy, or reader improvement with AI. Instead, it focuses on demonstrating substantial equivalence to a predicate device.

    Here's a breakdown of the information that is available, and what is missing:

    The document states:
    "The data in the Premarket Notification on safety and effectiveness supports a finding of substantial equivalence to toxicology calibrators already in commercial distribution. Stress stability studies of the DAT Low and High Urine Calibrators II support the Beckman stability claim of 12 months."

    This indicates that a study was performed to assess stability, and the overall data supported substantial equivalence. However, specific acceptance criteria for performance and the detailed results of such a study are not provided in the given text.

    Therefore, many of the requested sections regarding acceptance criteria, study details, ground truth, and expert involvement cannot be populated from the provided document.


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

    Acceptance CriteriaReported Device Performance
    Not provided in the document. The document primarily focuses on demonstrating substantial equivalence to a predicate device and stability. Specific performance metrics like accuracy, precision, sensitivity, or specificity with defined acceptance thresholds are not detailed.The device's "safety and effectiveness supports a finding of substantial equivalence to toxicology calibrators already in commercial distribution." Stress stability studies support a 12-month stability claim.

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

    • Sample size for test set: Not provided.
    • Data provenance: Not provided (e.g., country of origin, retrospective/prospective).

    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 information is not applicable as the device is a calibrator for laboratory assays, not an imaging device requiring expert interpretation for ground truth. Ground truth for calibrators would typically be established by known concentrations of analytes.

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

    This information is not applicable for a calibrator 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

    This information is not applicable as the device is a calibrator and not an AI-powered diagnostic tool, and there is no human-in-the-loop performance described.

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

    This information is not applicable as the device is a calibrator, not an algorithm.

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

    The "ground truth" for a calibrator like this would be the known, precisely manufactured concentrations of the substances (Barbiturates, Benzodiazepine, Methadone, Opiate 300 ng, Methaqualone, and Propoxyphene) within the calibrator solutions. The document does not explicitly state how these concentrations were verified, but it is an inherent characteristic of a calibrator.

    8. The sample size for the training set

    This information is not applicable as the device is a calibrator, not a machine learning algorithm that requires a "training set."

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

    This information is not applicable as the device is a calibrator, not a machine learning algorithm that requires a "training set."

    Intended Use

    The SYNCHRON® Systems DAT Low and High Urine Calibrators 1, in conjunction with SYNCHRON Reagents, are intended for use on SYNCHRON Systems for the calibrations of Amphetamines, Cocaine Metabolite, Opiate 2000 ng, and Phencyclidine enzyme immunoassays.

    Device Description

    The SYNCHRON® Systems DAT Low and High Urine Calibrators 1 are used for the calibrations of Amphetamines, Cocaine Metabolite, Opiate 2000 ng, and Phencyclidine enzyme immunoassay on Beckman SYNCHRON® Systems.

    AI/ML Overview

    Here's an analysis of the provided text regarding the SYNCHRON® Systems DAT Low and High Urine Calibrators 1, focusing on acceptance criteria and supporting study details:

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

    The provided text does not explicitly state quantitative acceptance criteria for the device performance beyond the general claim of "substantial equivalence to toxicology calibrators already in commercial distribution." However, it does mention a key performance study related to stability.

    Acceptance Criteria (Implied)Reported Device Performance
    Substantial equivalence to predicate toxicology calibrators."Supports a finding of substantial equivalence." (Overall)
    Stability for a specified duration."Stress stability studies... support the Beckman stability claim of 18 months."
    Ability to calibrate Amphetamines, Cocaine Metabolite, Opiate 2000 ng, and Phencyclidine enzyme immunoassays.Intended use statement confirms this function.

    2. Sample size used for the test set and the data provenance

    The document does not specify the sample size used for the stress stability studies or any other performance evaluation. It also doesn't mention the provenance (e.g., country of origin, retrospective/prospective) of the data.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    This information is not provided in the document. For calibrators, ground truth would typically be established through highly accurate reference methods or certified reference materials, not explicitly by human experts in the manner of diagnostic image interpretation.

    4. Adjudication method for the test set

    Not applicable/not mentioned. Adjudication methods are typically used in studies involving human interpretation or classification, not for the performance of a calibrator.

    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 calibrator for enzyme immunoassays, not an AI-assisted diagnostic tool. Therefore, MRMC studies and concepts of human reader improvement with AI assistance are not relevant.

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

    This concept is not directly applicable to a calibrator. The calibrator's performance is standalone in the sense that its values are objectively measured, but its role is to enable the accurate function of an immunoassay system, which is then used by a human. The document describes evaluations of the calibrator itself rather than a standalone diagnostic algorithm.

    7. The type of ground truth used

    For the stability studies, the ground truth would have been the accepted concentrations of the analytes (Amphetamines, Cocaine Metabolite, Opiate 2000 ng, and Phencyclidine) within the calibrator solutions, measured by highly accurate and traceable methods over time. The document doesn't explicitly state the method used to establish this ground truth, but it implies comparison to industry standards for toxicology calibrators.

    8. The sample size for the training set

    Not applicable. This device is a calibrator, not a machine learning algorithm, so there is no concept of a "training set."

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

    Not applicable, as there is no training set for a calibrator.
