    AI/ML Overview

    The provided document describes a Special 510(k) Summary for a modification to the Afinion™ AS100 Analyzer, specifically the addition of the Afinion™ Data Connectivity Converter (ADCC). This document focuses on the safety and efficacy of the ADCC and its integration with the existing cleared device.

    Crucially, the document does not contain acceptance criteria, reported device performance data, or detailed study results for the ADCC's performance in terms of diagnostic accuracy or clinical effectiveness. The study information provided is limited to design control activities and compliance with electrical and electromagnetic compatibility (EMC) standards.

    Therefore, many of the requested sections below cannot be populated with information from the provided text.

    Here's an attempt to answer the questions based on the available information:


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

    • Acceptance Criteria: The document does not explicitly state acceptance criteria in terms of diagnostic performance metrics (e.g., sensitivity, specificity, accuracy) for the ADCC. The acceptance criteria mentioned are related to successful completion of design control activities and compliance with safety and EMC standards.
    • Reported Device Performance: The document confirms the ADCC was tested and found to be in conformity with various electrical safety and EMC standards. It does not report performance data like data transfer speed, error rates, or successful connection rates, which would be typical performance metrics for a data connectivity device.
    Acceptance Criteria CategorySpecific Criteria (as inferred/stated)Reported Device Performance
    Design DevelopmentDesign Plan adherenceAgreement with design input/specifications
    Software TestingCode reviews, module testing, functional testingPerformed and considered in agreement with design input/specifications
    Hazard AnalysisNo unacceptable risks identifiedPerformed; no unacceptable risks found
    Electrical SafetyConformity with IEC 61010-1, IEC 61010-2-081, IEC 61010-2-101Tested and found to be in conformity
    EMC StandardsConformity with EN 61326-1, EN 61326-2-6, CFR 47 Part 15 Subpart BTested and found to be in conformity

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

    • The document does not describe a clinical "test set" or diagnostic performance study for the ADCC. The testing mentioned refers to engineering verification and validation activities (software testing, electrical safety, EMC). Therefore, no sample size or data provenance is provided for a diagnostic test set.

    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. The document does not describe a study involving expert-established ground truth for a diagnostic test set.

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

    • Not applicable. The document does not describe a diagnostic test set requiring 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

    • Not applicable. This is not an AI-assisted diagnostic device, but a data connectivity converter for an existing IVD analyzer. No MRMC study was conducted or is relevant.

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

    • Not applicable for diagnostic performance. While the ADCC itself functions automatically to transfer data, its "standalone performance" is described in terms of its technical functionality (extracting, converting, forwarding data) and compliance with relevant technical and safety standards, not diagnostic accuracy.

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

    • Not applicable for diagnostic performance. For the engineering tests mentioned, the "ground truth" would be adherence to specified technical requirements and industry standards.

    8. The sample size for the training set

    • Not applicable. This document pertains to a hardware and software accessory for data transfer, not a machine learning or AI algorithm development that would involve a "training set" in the conventional sense.

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

    • Not applicable, as there is no mention of a training set for an AI/ML algorithm.

    Device Description

    The Afinion™ ACR assay is an in vitro diagnostic test for quantitative determination of albumin, creatinine and albumin/creatinine ratio (ACR) in human urine using the Afinion™ AS100 Analyzer. The measure of urine albumin aids in the early diagnosis of nephropathy.

    The Afinion™ ACR Control kit contains liquid preparations of albumin and creatinine in citrate buffer. The controls should be used to confirm that the Afinion™ AS100 Analyzer System is working properly and provides reliable results.

    Afinion™ ACR is a fully automated assay for determination of albumin, creatinine and albumin/creatinine ratio (ACR) in human urine.

    The Afinion™ ACR Test Cartridge contains all the reagents necessary for determining albumin, creatinine and ACR in a human urine sample. The sample material is sampled using the sampling device integrated into the Test Cartridge.

    Albumin is quantified using a solid phase immunochemical assay. In the Afinion™ ACR Test Cartridge the sample is automatically diluted and aspirated through a membrane coated with antialbumin antibodies, which concentrates and immobilizes the albumin from the sample. A goldantibody conjugate then binds to the immobilized albumin resulting in a red-brown stained membrane. Excess gold-antibody conjugate is removed in a washing step. The Afinion™ AS100 Analyzer measures the color intensity of the membrane, which is proportional to the amount of albumin in the sample.

    Creatinine is quantified using an enzymatic colorimetric test that involves four enzymatic steps. The test requires incubation with two distinct enzyme solutions. A colored end product is measured in one of the cartridge wells.

    The concentration of albumin, the concentration of creatinine, and the calculated albumin/creatinine ratio are displayed on the Afinion™ AS100 Analyzer.

    AI/ML Overview

    Acceptance Criteria and Study Details for Afinion™ ACR

    1. Acceptance Criteria and Reported Device Performance

    The acceptance criteria for the Afinion™ ACR assay were implicitly established through its comparison to a legally marketed predicate device, the DCA 2000® Microalbumin/Creatinine assay (K963142). The goal was to demonstrate "substantial equivalence" in performance. While explicit numerical acceptance criteria were not provided in terms of thresholds for correlation coefficients or precision values, the reported device performance, demonstrating strong correlation and acceptable precision, was considered sufficient to meet the equivalence standard.

    Performance MetricAcceptance Criteria (Implicit)Reported Device Performance (External Study)Reported Device Performance (Internal Study)Reported Device Performance (External Precision Study)
    Method Comparison (Correlation with Predicate)Substantial Equivalence to DCA 2000®
    Albumin (mg/L)High correlation (e.g., r > 0.95 or similar)Y = 1.10x + 1.4, r = 0.99Y = 0.92x + 2.1, r = 0.99N/A
    Creatinine (mg/dL)High correlation (e.g., r > 0.95 or similar)Y = 0.93x + 2.3, r = 0.99Y = 1.00x - 3.2, r = 0.99N/A
    ACR (mg/g)High correlation (e.g., r > 0.95 or similar)Y = 1.16x + 1.0, r = 0.99Y = 1.01x + 0.7, r = 0.99N/A
    PrecisionAcceptable CV values for within-run and total precisionN/AN/A
    Within-run CV (all analytes)≤ 8% (implicit)N/AN/A≤ 8%
    Total CV (all analytes)≤ 9% (implicit)N/AN/A≤ 9%
    Control Precision (Afinion™ ACR Control)Acceptable CV values for within-day, within-site, and between-site precisionN/AN/A
    Within-day CV (all analytes)≤ 7% (implicit)N/AN/A≤ 7%
    Within-site CV (all analytes)≤ 7% (implicit)N/AN/A≤ 7%
    Between-site CV (all analytes)≤ 4% (implicit)N/AN/A≤ 4%

    2. Sample Size and Data Provenance

    • Test Set (Method Comparison - External Study):

      • Sample Size: 169 urine samples
      • Data Provenance: Studies were conducted at "four external study sites." The specific country of origin is not explicitly stated, but the submission is from Norway, hence it's likely European or international. The samples were retrospective, as they were "analyzed" with both devices.
    • Test Set (Method Comparison - Internal Study):

      • Sample Size: 91 urine samples for Albumin and ACR, 95 urine samples for Creatinine.
      • Data Provenance: "Internal method comparison study," implying the data originated from the manufacturer's own facilities. These were retrospective samples.
    • Test Set (Precision Study):

      • Sample Size: Not explicitly stated as a number of unique patient samples for the clinical precision study. Instead, it refers to "two levels of urine samples" (Sample 1 and Sample 2) run multiple times. For the control precision, controls were run in "6 replicates each day over 5 operating days."
      • Data Provenance: "External precision study" and "3 study sites" for controls.

    3. Number of Experts and Qualifications for Ground Truth

    The study relies on comparing the performance of the new device against a predicate device (DCA 2000® Microalbumin/Creatinine assay). Therefore, the "ground truth" for the test set is effectively the result obtained from the predicate device. No human experts were used to establish a separate, independent ground truth for the test samples in this specific type of comparison study. The predicate device itself acts as the reference standard.

    4. Adjudication Method

    Not applicable. Since the ground truth for comparison was the result from a predicate device, and the study focused on quantitative correlation and precision, there was no need for expert adjudication of results.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This submission is for an in vitro diagnostic (IVD) device, specifically an automated assay for quantitative measurement. This type of study is more common for imaging devices or those requiring human interpretation of results. The study design focuses on the analytical performance (accuracy, precision) of the device itself compared to a predicate device, not on how human readers' diagnostic performance might improve with or without AI assistance.

    6. Standalone (Algorithm Only) Performance

    Yes, the study describes the standalone performance of the Afinion™ ACR assay. It is an "automated assay" that "quantifies" albumin and creatinine, and "calculates" the ACR. The performance metrics (correlation coefficients, precision) presented are solely based on the device's measurements from urine samples, without human intervention in the result generation or interpretation to modify the output.

    7. Type of Ground Truth Used

    The "ground truth" used for evaluating the Afinion™ ACR assay was the results obtained from a legally marketed predicate device, the DCA 2000® Microalbumin/Creatinine assay (K963142). This is a common approach for demonstrating substantial equivalence for in vitro diagnostic devices. It relies on the established accuracy and reliability of the predicate.

    8. Sample Size for the Training Set

    The document does not explicitly mention a separate "training set" or its sample size in the context of device development. For IVD assays, development often involves extensive internal testing, calibration, and optimization using various samples, but this is usually distinct from the formal "training set" concept seen in AI/machine learning development.

    9. How Ground Truth for the Training Set was Established

    Given that this is an in vitro diagnostic assay and not a machine learning algorithm in the typical sense, there isn't a "training set" with ground truth established in the way one would for an AI model.

    The "standardization" section states that:

    • Albumin is calibrated against the ERM®-DA470 reference preparation.
    • Creatinine is calibrated against SRM 914a.

    These reference materials serve as the foundational "ground truth" for the device's calibration, ensuring that its measurements are traceable to recognized international standards. This calibration process, along with extensive internal testing and optimization (which would involve numerous samples with known values, likely determined through reference methods or predicate devices), forms the basis of the device's accuracy.
