    Device Description

    The Quest Diagnostics Hair Check-DT (Opiates) is a test system that utilizes the IDS One-Step ELISA Opiates Kit for the qualitative detection of opiates at or above 500 pg/mg in head hair samples from chronic heroin users.

    AI/ML Overview

    The provided document does not contain information about acceptance criteria or a study that proves the device meets specific acceptance criteria in the format requested.

    The document is a 510(k) clearance letter from the FDA for the Quest Diagnostics HairCheck-DT (Opiates) device. It states that the device is substantially equivalent to legally marketed predicate devices. It describes the intended use and indications for use, but it does not detail a study conducted by Quest Diagnostics to establish performance against pre-defined acceptance criteria.

    Specifically, the requested information points cannot be extracted from this document:

    1. Table of acceptance criteria and reported device performance: Not present.
    2. Sample size used for the test set and data provenance: Not present. The document refers to "head hair samples from chronic heroin users" but does not provide details on the sample size or origin of data from a specific study.
    3. Number of experts used to establish ground truth and qualifications: Not present.
    4. Adjudication method: Not present.
    5. Multi-reader multi-case (MRMC) comparative effectiveness study: Not applicable for this type of test system.
    6. Standalone performance: The document states the test system "provides only a preliminary analytical test result. A more specific alternate chemical must be used in order to obtain a confirmed result." This implies it's not truly standalone for a definitive diagnosis.
    7. Type of ground truth used: It mentions that GC-MS/MS is the preferred method for confirmation, indicating that this might serve as a form of "ground truth" for confirmed results, but it doesn't detail how ground truth was established for a specific validation study.
    8. Sample size for the training set: Not present.
    9. How ground truth for the training set was established: Not present.

    The document is primarily a regulatory clearance, not a scientific study report. To find the information requested, one would typically need to consult a detailed validation study report submitted as part of the 510(k) application, which is not included in these pages.
