    Intended Use

    Use the Celerity Incubator to incubate and automatically read STERIS Celerity Biological Indicators for Steam and Vaporized Hydrogen Peroxide sterilization at 55°C - 60°C for a fluorescent result.

    Device Description

    The Celerity Incubator incubates and reads fluorescent Vaporized Hydrogen Peroxide (VHP) and Steam Biological Indicators (BIs). The BI is incubated at 59°C with an acceptable tolerance of -4°C/+1°C. During incubation, the BI is monitored for a potential fluorescence signal generated as a result of the production of a-glucosidase. When a growth response has been detected or when the required incubation time has elapsed, the incubator indicates the results to the user.

    AI/ML Overview

    Here's an analysis of the provided text regarding the Celerity Incubator's acceptance criteria and studies:

    1. Table of Acceptance Criteria and Reported Device Performance

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

    The provided document does not explicitly state the sample size used for the "Qualification Testing with intended Biological Indicators" which is the most relevant performance test described. It also does not specify the data provenance (e.g., country of origin, retrospective or prospective nature).

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

    The document does not specify the number of experts used or their qualifications for establishing the ground truth. The acceptance criterion mentions "7-day grow out per FDA guidance," implying a standard microbiological method for determining growth, which typically doesn't involve "experts" in the sense of clinical reviewers.

    4. Adjudication Method for the Test Set

    The document does not describe an adjudication method. The "7-day grow out" is a definitive biological outcome, not typically subject to adjudication in the same way clinical image reviews might be.

    5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done

    No, an MRMC comparative effectiveness study was not done. The device is an incubator for biological indicators, not a diagnostic imaging or AI-assisted diagnostic tool that would typically involve human readers.

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

    Yes, a standalone performance test was done, referred to as "Qualification Testing with intended Biological Indicators." This test assesses the device's ability to accurately detect fluorescence in biological indicators, which is an automated process without human interpretation in the results pathway. The "human factors" test evaluates user interaction, but the core performance related to detecting BI growth is standalone.

    7. The Type of Ground Truth Used

    The type of ground truth used for the "Qualification Testing with intended Biological Indicators" is biological growth/non-growth, as determined by a "7-day grow out" method. This is a functional, objective ground truth based on the viability of microorganisms.

    8. The Sample Size for the Training Set

    The document does not provide information on a training set sample size. This is because the Celerity Incubator is a hardware device with embedded software for interpreting biological indicator results based on a known biochemical reaction (fluorescence). It doesn't appear to be an AI/machine learning model in the typical sense that would require a separate training set for algorithm development.

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

    As there is no mention of a traditional training set for an AI/ML algorithm, the concept of establishing ground truth for a training set in this context is not applicable or described in the document. The device's operation is based on established principles of fluorescence detection for biological activity, rather than learning from a dataset.
