    Intended Use

    STA-R® Automated Multi-Parametric Analyzer is a fully automatic 311 TV Tratomated for the performance of tests on human ellinear in the results of which aid in the diagnosis of coagulation abnormalities or in monitoring anticoagulant therapy.

    Device Description

    The STA-R® instrument is a fully automatic laboratory analyzer designed to perform tests which aid in the diagnosis of coagulation abnormalities or in monitoring anticoagulant therapy. Once test samples and reagents are loaded onto the instrument, sample handling, reagent delivery, analysis and reporting of test results are performed automatically, making the STA-R® instrument a true "walk-away" system. A central processing unit controls instrument functions, including management of patient results, quality control, scheduling of instrument maintenance and workload organization. The instrument utilizes Diagnostica Stago (France) reagents, and is open to adaptation of other reagents currently commercially available from third-party manufacturers. Bar-coding of test reagents, calibrators and controls facilitates their use on the system and makes reagent management simple. Manual entry of reagent information enables the utilization of non barcoded reagents. The instrument performs multiple test methodologies in random access (as selected by the user); these include clot-based tests and photometric assays at predetermined wavelengths.

    AI/ML Overview

    The provided text contains limited information regarding acceptance criteria and a study to prove the device meets these criteria. The document is primarily a 510(k) clearance letter and a summary of the device's characteristics, focusing on its substantial equivalence to a predicate device.

    Here's an attempt to answer your questions based only on the provided text, highlighting what is not available:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance CriteriaReported Device Performance
    Not explicitly stated in terms of specific performance metrics (e.g., accuracy, precision, correlation with a gold standard). The primary "acceptance criteria" for 510(k) clearance here is substantial equivalence to the predicate device."Sample-to-sample carry-over has been demonstrated to be so low as to be undetectable."
    Substantial equivalence to the commercially available STA® analyzer (K942117).The STA-R® instrument is substantially equivalent to the commercially available STA® analyzer, also from the same manufacturer (Diagnostica Stago, France), that received 510(k) clearance under K942117.

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

    This information is not available in the provided text. The document refers to the demonstration of "sample-to-sample carry-over" but does not specify the sample size or details about the test set used for this demonstration or for establishing substantial equivalence.

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

    This information is not available in the provided text. The evaluation for substantial equivalence would have been performed by the FDA, but the internal studies by the manufacturer or the specific ground truth establishment methods are not detailed.

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

    This information is not available in the provided text.

    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

    A MRMC study is not applicable here. The device is an automated laboratory analyzer, designed to perform tests, not to assist human readers in interpreting images or complex data in the same way an AI diagnostic tool would. The product itself automates the analysis.

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

    The device is described as "fully automatic" and a "true 'walk-away' system" that performs "sample handling, reagent delivery, analysis and reporting of test results... automatically." This suggests that its performance is standalone, without human intervention in the analysis process itself. However, a specific "standalone study" with detailed metrics is not described beyond the general statement of functionality.

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

    The type of ground truth used for establishing the performance or substantial equivalence is not explicitly stated. For a coagulation analyzer, ground truth would typically refer to reference methods or established assays for coagulation measurements.

    8. The sample size for the training set

    This information is not available in the provided text. The device is a physical instrument, not a machine learning algorithm in the typical sense that would require a "training set" of data for model development. Its development likely involved engineering, calibration, and testing against known standards and samples, but not "training data" in the AI context.

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

    As in point 8, the concept of a "training set" and its "ground truth" as relevant to AI algorithm development is not applicable here. The development would have involved engineering design, adherence to technical specifications, and validation against established scientific and laboratory standards.

    Intended Use

    The ASSERACHROM® tPA test kit is intended for the quantitative determination of tissue-type plasminogen activator (tPA) antigen in citrated plasma by the sandwich technique of enzyme immunoassay (EIA) known as enzyme-linked immunosorbent assay (ELISA).

    The quantitative determination of tPA is generally performed during the assessment of the fibrinolytic system of a patient, for instance, following a thrombotic episode.

    In addition, it has been reported that a high antigenic level of tPA is associated with a greater risk of myocardial infarction or vascular cerebral accident. Finally, quantitative tPA assays are useful in the detection of hypofibrinolytic and hyperfibrinolytic states.

    Device Description

    The ASSERACHROM® tPA test kit is intended for the quantitative determination of tissue-type plasminogen activator (tPA) antigen in citrated plasma by the sandwich technique of enzyme immunoassay (EIA) known as enzyme-linked immunosorbent assay (ELISA).

    Mouse monoclonal anti-tPA antibody is coated on the inside wall of a plastic microwell. The plasma to be tested is allowed to incubate in the microwell for two hours at room temperature, during which any tPA present is captured by the monoclonal antibody. Next, a second (and different) mouse monoclonal anti-tPA antibody coupled with peroxidase is added to the microwell for another 2-hour incubation at room temperature; this antibody-enzyme conjugate binds to another antigenic determinant of the tPA molecule that is already bound to the microwell in the first incubation step. The bound enzyme is revealed by its action on orthophenylenediamine in the presence of hydrogen peroxide to produce a yellow color; after addition of a strong acid to stop the enzymatic action, the intensity of the color developed bears a direct relationship to the tPA level initially present in the test plasma.

    The kit provides sufficient reagents to perform 96 tests in micro-ELISA plate format. Reagents in intact (unopened) kits remain stable for 18 months after their date of manufacture, when stored at 2°-8°C. Reconstituted reagent stabilities are as follows: Reagent ● (antibody-coated microwell strips) must be used immediately after opening of its package; Reagent @ (anti-tPA-Peroxidase), 24 hours at 2°-8°C; Reagent Oa (ortho-Phenylenediamine) dissolved together with Reagent Ob (Urea Peroxide), 1 hour at room temperature (18°-25°C); 1:10 diluted Reagent © (Dilution Buffer) and 1:20 diluted Reagent ® (Washing Solution), 15 days at 2°-8°C, when free of any contamination; both the Reagent ® (tPA Calibrator) and Reagent ® (tPA Control), 4 hours at 20°C.

    The ASSERACHROM® tPA reagent system has a detection limit of 1 ng/ml; a working range from 1 ng/ml up to the tPA level of Reagent ® (tPA Calibrator, up to 50 ng/ml); intra-assay reproducibility of

    Intended Use

    The STA® Liatest® Control [N]+[P] kit is intended for use as control plasmas (Normal and Abnormal levels) for von Willebrand Factor (vWF) and D-dimer antigen assays by the immuno-turbidimetric method performed on STA® analyzers (Diagnostica Stago, France: STA® full-size model, K942117; STA® Compact model, K961579).

    Device Description

    The STA®-Liatest® Control [N]+[P] kit provides two citrated human plasmas intended for use as normal and abnormal controls for von Willebrand Factor (vWF) and D-dimer antigen assays by the immino-turbidimetric method performed on STA® analyzers (Diagnostic Stago, France: STA® full-size model and STA® Compact model).

    Each STA®-Liatest® Control [N]+[P] kit provides 12 x 1-ml vials of freeze-dried human plasma containing vWF and D-dimer at normal levels (STA®-Liatest® Control [N]) and 12 x 1-ml vials of freeze-dried human plasma containing vWF and D-dimer at abnormal levels (STA®-Liatest® Control [P]).

    Both the normal and abnormal plasmas in the freeze-dried state are stable for 24 months after the date of manufacture, when stored at 2°-8°C; after reconstitution with water, both plasmas are stable for 8 hours on board STA® analyzers.

    AI/ML Overview

    The provided text does not contain typical acceptance criteria and study results in the format expected for medical device performance evaluation. This document is a 510(k) Premarket Notification for a control kit (STA®-Liatest® Control [N]+[P] Kit), which is used to ensure the proper functioning of other assays, specifically for von Willebrand Factor (vWF) and D-dimer antigen.

    For a control kit, "acceptance criteria" usually relate to the stability and consistency of the control material itself, rather than performance metrics like sensitivity, specificity, or AI accuracy that would be expected for a diagnostic device. The provided text describes the product, its intended use, and its stability.

    Here's the breakdown of what can be extracted or inferred, and what is missing based on your requested format:

    What can be inferred from the provided text:

    • Device: STA®-Liatest® Control [N]+[P] Kit
    • Intended Use: Normal and abnormal controls for vWF and D-dimer antigen assays by the immuno-turbidimetric method performed on STA® analyzers.
    • Purpose of the "Study" mentioned (implicitly): To demonstrate the stability of the control plasmas.

    What is present regarding "Acceptance Criteria" (interpreted for a control kit):

    Acceptance Criteria (Inferred from text)Reported Device Performance (from text)
    Stability (Freeze-dried state): Control plasmas should be stable for a specified duration at a given temperature.24 months after the date of manufacture, when stored at 2°-8°C.
    Stability (After reconstitution): Control plasmas should be stable for a specified duration after reconstitution.8 hours on board STA® analyzers.

    Missing Information (as per your request, because this is for a control kit, not a diagnostic device with AI):

    The following points are not applicable or not provided in the context of this 510(k) submission for a control kit:

    1. Sample size for the test set and data provenance: Not explicitly stated for performance validation. The "study" here is likely internal manufacturing/stability testing, not a clinical trial with a "test set" of patients.
    2. Number of experts used to establish the ground truth for the test set and qualifications: Not applicable for a control kit. Ground truth for a control kit refers to the known concentrations of its analytes, established during manufacturing.
    3. Adjudication method for the test set: Not applicable.
    4. Multi-reader multi-case (MRMC) comparative effectiveness study: Not applicable. This kit controls human readers of an assay, it is not an AI algorithm assisting human readers.
    5. Standalone (algorithm-only) performance: Not applicable, as this is a physical control substance, not an algorithm.
    6. Type of ground truth used: For a control, the "ground truth" would be the assayed values of vWF and D-dimer established during manufacturing, possibly against a reference standard. The text doesn't specify how these were established.
    7. Sample size for the training set: Not applicable. Control kits don't have "training sets."
    8. How the ground truth for the training set was established: Not applicable.

    In summary: The provided document is a regulatory approval for a control kit, not a performance study of a diagnostic device with AI. Therefore, most of your requested detailed study information is not available and not relevant to this specific type of device. The document primarily focuses on the product description and its stability claims.

    Intended Use

    The STA®-Liatest® D-Di test kit is intended for use with STA® analyzers (Diagnostica Stago, France: STA® full-size model, K942117; STA® Compact model, K961579) to perform quantitative determinations of D-dimer antigen levels in citrated plasma by the immuno-turbidimetric method based on the measurement of light absorbance produced by a suspension of microlatex particles coated with mouse anti-human D-dimer monoclonal antibodies.

    Device Description

    The STA®-Liatest® D-Di test kit is intended for use with STA® analyzers to perform quantitative assays of D-dimer antigen in citrated plasma by the immuno-turbidimetric method based on the measurement of light absorbance produced by a suspension of microlatex particles coated with specific mouse anti-human D-dimer monoclonal antibodies.

    Each STA®-Liatest® D-Di test kit provides: 6 x 5-ml vials of ready-for-use Tris buffer and 6 x 6-ml vials of a suspension of microlatex particles coated with mouse anti-human D-dimer monoclonal antibodies.

    Reagents in intact vials remain stable for 18 months after the date of manufacture, when stored at 2°-8°C. After opening of the vials, kit reagents (with STA®-Reducers and perforated caps installed on the vials) are stable for 15 days on board STA® analyzers.

    AI/ML Overview

    The provided text does not contain detailed acceptance criteria or a study proving the device meets specific performance metrics. Instead, it describes a 510(k) premarket notification for a medical device, the STA®-Liatest® D-Di Test Kit, which indicates it has been found "substantially equivalent" to a predicate device. This substantial equivalence determination generally means that the new device is as safe and effective as a legally marketed device that is not subject to premarket approval.

    Here's a breakdown of the requested information based on the provided text, and where the information is not available:

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

    Acceptance CriteriaReported Device Performance
    Not specified in the provided text. The document focuses on substantial equivalence, not explicit performance criteria for the new device.The STA®-Liatest® D-Di test kit "demonstrated substantial equivalence" to the commercially available ASSERACHROM® D-Di kit. This implies performance is comparable to the predicate, but specific metrics are not detailed for the new device.

    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: Not specified.
    • Data provenance: Not specified.

    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)

    • Not applicable/Not specified. The substantial equivalence claim is made against a predicate device, not by establishing ground truth based on expert consensus for the new device's performance.

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

    • Not applicable/Not specified. The document does not describe a test set or an adjudication process for such a set.

    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

    • No. This device is an in-vitro diagnostic test kit (an immuno-turbidimetric method), not an AI-powered diagnostic tool requiring human reader interpretation in the context of an MRMC study.

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

    • Not applicable. This is an automated laboratory test kit; its performance is inherently "standalone" in the sense that the analyzer performs the measurement. However, it's not an "algorithm only" in the context of AI.

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

    • The ground truth for chemical assays like D-dimer is typically established through reference methods or validated standards. The document states the new device is "substantially equivalent" to the ASSERACHROM® D-Di kit, which is a "microtiter ELISA-based procedure." This implies the predicate device's established performance serves as the benchmark. The inherent ground truth for D-dimer measurements relates to the actual concentration of D-dimer antigen in the plasma, which would be determined by a highly accurate and precise analytical method. The document does not specify details on how the accuracy of either device was independently validated against a gold standard.

    8. The sample size for the training set

    • Not applicable/Not specified. This device is a reagent kit and analyzer system, not a machine learning algorithm that requires a "training set" in the conventional sense of AI development.

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

    • Not applicable/Not specified. As mentioned above, there is no "training set" in the context of an AI algorithm for this device.

The freeze-dried reagent in intact vials is stable for 24 months after the date of manufacture, when stored at 2°-8°C; the reconstituted plasma remains stable for 4 hours on board STA® analyzers.

    AI/ML Overview

    The provided text primarily focuses on the regulatory approval of the STA® D-Di Calibrator Kit and its intended use as a calibration plasma. It does not contain information about acceptance criteria or a study that proves the device meets those criteria in the context of device performance metrics such as sensitivity, specificity, or accuracy.

    The document is a 510(k) clearance letter from the FDA, indicating that the device has been found substantially equivalent to a predicate device. This type of submission generally relies on demonstrating equivalence rather than providing detailed performance studies against specific acceptance criteria for a new device's efficacy or diagnostic accuracy.

    Therefore, I cannot fulfill your request for:

    1. A table of acceptance criteria and reported device performance.
    2. Sample size used for the test set and data provenance.
    3. Number of experts used to establish ground truth and their qualifications.
    4. Adjudication method.
    5. MRMC comparative effectiveness study results.
    6. Standalone performance results.
    7. Type of ground truth used.

    Reagents in intact vials remain stable for 18 months after the date of manufacture, when stored at 2°-8°C. After opening of the vials or after dilution, kit reagents are stable for 15 days on board the STA® analyzer.

    AI/ML Overview

    I am sorry, but the provided text from K96X625 does not contain the detailed information necessary to answer your request. The document is a 510(k) premarket notification for a medical device from 1990, and it focuses on demonstrating substantial equivalence to an existing device rather than providing a detailed study design with acceptance criteria, sample sizes, expert qualifications, or ground truth establishment as would be present in a more modern clinical study report.

    Specifically, the text is a Safety and Effectiveness Summary and only states:

    • Intended Use: Quantitative assays of von Willebrand Factor (vWF) antigen in citrated plasma by an immuno-turbidimetric method using the STA® analyzer.
    • Components: Description of the kit contents (buffer, microlatex particles with antibodies, diluent).
    • Stability: Shelf life of unopened and opened/diluted reagents.
    • Substantial Equivalence Claim: "The proposed STA®-Liatest® vWF test kit has demonstrated substantial equivalence to the commercially available ASSERA®-PLATE vWF kit (Diagnostica Stago, France; K861417) which is an electro-immunodiffusion procedure for the quantitative determination of vWF antigen levels in citrated plasma."

    The document does not provide information on any of the following, which are crucial for your request:

    1. Acceptance criteria and reported device performance: While it claims substantial equivalence, it doesn't list specific performance metrics (e.g., sensitivity, specificity, accuracy, precision, correlation coefficients) or the thresholds for those metrics that were considered "acceptable."
    2. Sample size, data provenance: No details on the number of samples, where they came from, or if they were retrospective/prospective.
    3. Number/qualifications of experts, adjudication method: This would not typically be relevant for a lab-based immunoassay unless there was a subjective interpretation component, which isn't indicated. However, there's no mention of any expert involvement for establishing ground truth.
    4. MRMC comparative effectiveness study: This is not applicable to an in vitro diagnostic (IVD) device like a vWF test kit. MRMC studies are typically for image-based diagnostic aids or AI algorithms that assist human interpretation.
    5. Standalone performance: While the device has standalone performance (it generates a quantitative vWF value), the document doesn't provide specific performance metrics in isolation from the comparison to the predicate.
    6. Type of ground truth: Not explicitly stated, but for a quantitative assay, the "ground truth" would generally be established by a reference method or highly characterized samples, which is not detailed here.
    7. Training set sample size and ground truth establishment (for AI): This is not an AI device, so these concepts are irrelevant to the provided text.

    To answer your questions as specified, you would need a detailed study report or clinical trial results for a more modern device, especially one involving AI or subjective interpretation. This document is too high-level and focused on regulatory equivalence for an IVD from 1990.

    Device Description

    Each STA®-VWF Control [N]+[P] kit provides 12 x 1-ml vials of freeze-dried human plasma containing vWF at the normal level (STA®-vWF Control [N]) and 12 x 1-ml vials of freeze-dried human plasma containing vWF at the abnormal level (STA vWF Control [P]). Both the normal and abnormal plasmas in the freeze-dried state are stable for 24 months after the date of manufacture, when stored at 2°-8°C; after reconstitution with water, both plasmas are stable for 8 hours on board the STA® analyzer.

    AI/ML Overview

    This document, K962674, is a 510(k) Premarket Notification for a control kit used in conjunction with a diagnostic device, specifically the STA®-vWF Control [N]+[P] kit. It is not describing a diagnostic device that produces a "result" in the traditional sense that would require performance metrics like sensitivity, specificity, or and AUC, or involve human readers or AI.

    Therefore, many of the requested categories (like sample size for test set, number of experts, adjudication, MRMC, standalone performance, training set details) are not applicable to this type of submission.

    Here's an attempt to answer the relevant aspects based on the provided text, while clearly indicating where information is not available or not applicable:


    Acceptance Criteria and Device Performance for STA®-vWF Control [N]+[P] Kit

    This submission describes a control kit, not a diagnostic device with performance metrics related to diagnostic accuracy. The "acceptance criteria" and "device performance" in this context refer to the product's ability to serve its intended function as a quality control.

    Acceptance Criteria CategoryReported Device PerformanceComments
    Intended UseProvides two citrated human plasmas for use as normal and abnormal controls for vWF antigen assays by immuno-turbidimetric method on the STA® analyzer.The description confirms the kit contains these components for this purpose.
    vWF Value AssignmentEach manufactured lot is assigned vWF values (normal and abnormal levels).This process is described.
    vWF Value ReferencingvWF values are determined with an internal WF reference that has been assayed against the third International Standard 91/666 for Factor VIII and von Willebrand Factor (1992).This establishes traceability to an international standard.
    Kit Contents12 x 1-ml vials of freeze-dried plasma (normal level) and 12 x 1-ml vials of freeze-dried plasma (abnormal level).This matches the product description.
    Shelf Stability (Freeze-dried)Stable for 24 months after manufacture when stored at 2°-8°C.This is explicitly stated.
    On-board Stability (Reconstituted)Stable for 8 hours on board the STA® analyzer after reconstitution with water.This is explicitly stated.

    Study Details:

    1. Sample size used for the test set and the data provenance:

      • Test Set Sample Size: Not applicable. This is not a study evaluating a diagnostic device's performance on patient samples. Instead, it's about the quality and consistency of a control product.
      • Data Provenance: Not applicable in the context of a diagnostic performance study. The "data" pertains to the characterization and stability of the control plasma itself.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • Not applicable. Ground truth in this context relates to the assigned vWF values and stability characteristics, which are determined through laboratory testing and referencing, not expert consensus on patient interpretations.
    3. Adjudication method for the test set:

      • Not applicable. There is no "adjudication" of patient results or interpretations involved.
    4. 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 is not a diagnostic device, and therefore no human-in-the-loop AI studies would be relevant.
    5. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

      • Not applicable. This is not an algorithmic device.
    6. The type of ground truth used:

      • For the vWF value assignment, the "ground truth" is established by referencing against the third International Standard 91/666 for Factor VIII and von Willebrand Factor (1992).
      • For stability, the ground truth is established through laboratory testing to determine the duration the product maintains its specified characteristics under defined storage conditions.
    7. The sample size for the training set:

      • Not applicable. This is not a machine learning or algorithmic device that requires a training set.
    8. How the ground truth for the training set was established:

      • Not applicable for the same reason as above.

    Intended Use

    The STA Compact instrument is a fully automated laboratory analyzer designed to perform tests which aid in the diagnosis of coagulation abnormalities or in monitoring anticoagulant therapy.

    Device Description

    The STA Compact instrument is a fully automated laboratory analyzer designed to perform tests which aid in the diagnosis of coagulation abnormalities or in monitoring anticoagulant therapy. Once samples and test reagents are loaded onto the instrument, sample handling. reagent delivery, analysis and reporting of test results are performed automatically, making the STA Compact instrument a true walkaway system. A central processing unit controls instrument functions, including management of patient results, quality control, scheduling of instrument maintenance and workload organization. The instrument utilizes Diagnostica Stago (France) reagents, and is open to adaptation of other reagents currently available from third-party manufacturers. Barcoding of test reagents, calibrators and controls facilitates their use on the system and makes reagent management simple. Manual entry of reagent information enables the use of non-barcoded reagents. The instrument performs multiple test methodologies in random access (as selected by the user); these include clot-based tests and photometric assays at predetermined wavelengths.
