    Device Description

    The ANALETTE™ Chemistry Analyzer is an in vitro diagnostic automated clinical chemistry analyzer for the analysis of analytes in solution. It is an "open" System, which can use a variety of commercially manufactured reagents.

    AI/ML Overview

    The document describes the acceptance criteria and the study conducted to demonstrate the substantial equivalence of the Precision Systems™ ANALETTE™ Chemistry Analyzer using STANBIO Laboratory Reagents to its predicate devices (ANALETTE™ using Synermed® Reagents and ANALETTE™ using Medical Analysis Systems Inc® Reagents).

    Here's an analysis based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance:

    The document explicitly states: "Performance specifications: None established under Section 514." Instead, it refers to "Acceptance Criteria" (Exhibit E and F) but does not detail the specific numerical acceptance criteria within the provided text.

    However, the "Results" section (G.) provides the reported performance relative to "acceptable/equivalent results" or "Manufacturers' claim."

    Performance MetricAcceptance Criteria (Implied/Referenced)Reported Device Performance
    ImprecisionAcceptable/equivalent results (Implied)Serum controls give acceptable/equivalent results using the described procedure for within run and total imprecision with each of the representative test methods (Synermed, Medical Analysis Systems, and STANBIO Laboratory Reagents, as shown in Table 1 and Table 2 vs insert values).
    CorrelationAcceptable results (Implied)Slopes, Intercepts and Correlation Coefficients show acceptable results. The regression (slope and intercept) and correlation coefficients are shown in Table 3 and Graphs 1-21. Acceptable results are shown between both methods (STANBIO Laboratory Reagents vs. Synermeds® or Medical Analysis Systems Reagents).
    LinearityNot exceeding Manufacturers' claimLinearity did not exceed the Manufacturers' claim (shown in Table 4 vs insert values). A comparison is made between STANBIO Laboratory Reagents and the Least Square line to establish linearity.
    RecoveryAcceptable results for assigned rangesAcceptable results are shown between both methods (using assigned control serums ranges, shown in Table 5).
    Normal RangeRemains as recommended by manufactureParameters were not tested, assumed to remain as recommended by manufacture as no modifications to STANBIO Laboratory Reagents or packaging.
    SensitivityRemains as recommended by manufactureParameters were not tested, assumed to remain as recommended by manufacture as no modifications to STANBIO Laboratory Reagents or packaging.
    StabilityRemains as recommended by manufactureParameters were not tested, assumed to remain as recommended by manufacture as no modifications to STANBIO Laboratory Reagents or packaging.

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

    • Imprecision: Two control serums were used for both within-run and total precision.
      • Within-run: Up to 20 repeats.
      • Total precision: Duplicates for up to 20 days.
    • Correlation: "about 100 serums" were used.
    • Linearity: "Commercially available linearity material" was assayed.
    • Recovery: "Commercial available Controls with assigned values" were used.

    Data Provenance: The document does not specify the country of origin for the data or explicitly state if it was retrospective or prospective. However, the nature of the tests (using control serums, commercial linearity material, and patient serums for correlation by assaying them) suggests it was a prospective study conducted for the purpose of this 510(k) submission.

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

    This information is not provided in the document. The "ground truth" for the test set appears to be established by comparing the performance of the STANBIO Laboratory Reagents on the ANALETTE™ to the performance of predicate reagents (Synermed® and Medical Analysis Systems Inc® Reagents) on the same ANALETTE™ or to manufacturer's claims for linearity and recovery. This is a comparison study, not a ground truthing exercise with independent experts reviewing clinical cases.

    4. Adjudication Method for the Test Set:

    This information is not applicable as the study described is a laboratory performance study comparing reagent efficacy, not a human reader or image-based diagnostic study requiring adjudication. The performance is assessed against established laboratory methods or manufacturer claims for the predicate reagents.

    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 is not applicable as the device is a chemistry analyzer and reagents, not an AI-assisted diagnostic tool for human readers. No MRMC study was conducted.

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

    This is an algorithm-only (standalone) performance study in the sense that it evaluates the analytical performance of the ANALETTE™ Chemistry Analyzer with STANBIO reagents. The purpose is to demonstrate that the device produces accurate measurement results independently. Human intervention is limited to operating the analyzer and interpreting the numerical output.

    7. The Type of Ground Truth Used:

    The "ground truth" in this context is established by:

    • Comparison to Predicate Devices/Reagents: For imprecision and correlation, the performance of the STANBIO reagents is compared to the performance of legally marketed Synermed® and Medical Analysis Systems Inc® reagents on the ANALETTE™ device (which effectively act as the reference standard).
    • Manufacturer's Claims/Expected Values: For linearity and recovery, the results are compared against the manufacturer's claims for the reagents or assigned values for commercial controls.

    This is therefore a form of comparative analytical performance against established and accepted methods/claims, rather than clinical outcomes or pathology reports.

    8. The Sample Size for the Training Set:

    This information is not applicable as the ANALETTE™ is a chemistry analyzer, not a machine learning or AI-based device that requires a "training set" in the conventional sense. The "training" for such a system would involve instrument calibration and quality control procedures, which are standard for laboratory devices.

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

    This information is not applicable for the reasons stated above (not an AI/ML device requiring a training set with established ground truth).

    Effectiveness: June 14, 2002 | ClassificationName: | Chemistry analyzer, micro | 862.2500

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticPediatricDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The Precision Systems™ ANALETTE™ Chemistry Analyzer is intended for the quantitative determination of Calcium, Creatinine, Phosphorus, Albumin, Total Protein, Glucose, Urea Nitrogen, Magnesium, Creatine Kinase, Alkaline Phosphatase, Carbon Dioxide, Amylase, Cholesterol(includes HDL), Triglycerides, Total Bilirubin, Direct Bilirubin, Uric Acid, Lactate Dehydrogenase L, Lactate Dehydrogenase P, Alanine Aminotransferase. Aspartate Aminotransferase; Gamma Glutamyl Transferase, Lipase, Chloride, and etc. analytes in solution such as serum, plasma, or urine. It is an "open" System, which can use a variety of commercially manufactured reagents such as but not limited to Synermeds® Reagents and Medical Analysis Systems Reagents. It is used to monitor various physiological diseases or conditions. Precision Systems Inc will distribute, recommend and sales MAS Reagents without any modification of MAS packaging using PSI Applications sheets.

    Device Description

    An in vitro diagnostic automated clinical chemistry analyzer for the analysis of analytes in solution.

    AI/ML Overview

    Here's an analysis of the provided text regarding the acceptance criteria and study for the ANALETTE™ clinical chemistry analyzer and Medical Analysis Systems Reagents:

    1. Table of Acceptance Criteria and Reported Device Performance

    The provided text describes a submission for substantial equivalence (510(k)) for the ANALETTE™ clinical chemistry analyzer using Medical Analysis Systems (MAS) Reagents, comparing it to the same ANALETTE™ analyzer using Synermeds® 072 reagents (the predicate device). The core of the acceptance criteria here is the demonstration of "substantial equivalence" of the new reagent system to the predicate. Specific quantitative acceptance criteria are not explicitly detailed in the provided text in the form of numerical thresholds for accuracy, precision, or comparison studies. Instead, the performance section broadly states:

    Acceptance CriteriaReported Device Performance
    Substantial equivalence to the predicate device (ANALYETTE™ with Synermeds® 072 reagents)"Substantially equivalence was established in comparative studies. It was concluded from these results that this product is safe and effective."
    Effective performance for the quantitative determination of various analytes in solution (serum, plasma, or urine).The device is intended for the quantitative determination of a comprehensive list of analytes (Calcium, Creatinine, Phosphorus, Albumin, Total Protein, Glucose, Urea Nitrogen, Magnesium, Creatine Kinase, Alkaline Phosphatase, Carbon Dioxide, Amylase, Cholesterol (includes HDL), Triglycerides, Total Bilirubin, Direct Bilirubin, Uric Acid, Lactate Dehydrogenase L, Lactate Dehydrogenase P, Alanine Aminotransferase, Aspartate Aminotransferase, Gamma Glutamyl Transferase, Lipase, Chloride). The statement of substantial equivalence implies effective performance.
    Safety of the device."It was concluded from these results that this product is safe and effective."

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

    The document states that "comparative studies" were conducted. However, it does not provide any details regarding the sample size used for the test set or the data provenance (e.g., country of origin, retrospective or prospective nature).

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

    This information is not provided in the document. For a clinical chemistry analyzer, the ground truth is typically established by reference methods or highly accurate laboratory instruments rather than expert adjudication in the way it would be for image-based diagnostics.

    4. Adjudication Method (e.g., 2+1, 3+1, none) for the Test Set

    This information is not applicable in the context of a clinical chemistry analyzer's performance evaluation as described. Ground truth is established through analytical measurements, not through human adjudication of diagnostic findings. Therefore, no adjudication method like 2+1 or 3+1 would be used.

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

    No, an MRMC comparative effectiveness study was not done for this device. MRMC studies are typically used for diagnostic imaging devices where human interpretation is a critical component, often comparing human readers with and without AI assistance. This device is a clinical chemistry analyzer, which provides quantitative measurements directly.

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

    The performance described for the ANALETTE™ clinical chemistry analyzer with MAS reagents is inherently a standalone performance in the context of the instrument measuring analyte concentrations. There is no "human-in-the-loop" performance component in the direct measurement by the analyzer. The comparison is between two reagent systems on the same analyzer, assessing the analytical performance.

    7. The Type of Ground Truth Used

    The ground truth for this type of device (a clinical chemistry analyzer) would typically be established by:

    • Reference standard methods: Highly accurate and precise laboratory methods, often more complex or expensive than routine clinical tests.
    • Certified reference materials: Samples with known, validated concentrations of the analytes.
    • Comparison to the predicate device: For a 510(k) submission seeking substantial equivalence, the performance of the new device (or reagent system) is directly compared to the legally marketed predicate device using patient samples and/or quality control materials. The predicate device's results serve as the pragmatic "ground truth" for demonstrating equivalence in a clinical setting.

    The document implies the latter, stating "Substantially equivalence was established in comparative studies," meaning performance was compared against the predicate system.

    8. The Sample Size for the Training Set

    This information is not provided in the document. Clinical chemistry analyzers and their associated reagents are developed through analytical validation, which involves extensive testing, but the term "training set" is more commonly associated with machine learning algorithms. If there were any computational models or algorithms within the analyzer's software that required training (which is not explicitly indicated as relevant here beyond basic instrument calibration), the details of such a training set are absent.

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

    Since no "training set" in the machine learning sense is explicitly mentioned or detailed, and the focus is on analytical performance comparison (substantial equivalence), the method for establishing ground truth for a training set is not applicable or provided. The development of a clinical chemistry reagent kit involves rigorous analytical validation, where performance characteristics like accuracy, precision, linearity, and interference are established using known standards and patient samples, rather than a "ground truth for training" in the way an AI model would be trained.

    Intended Use

    The Precision Systems ANALETTE Chemistry Analyzer is intended for the quantitative determination of analytes in solutions, such as serum, plasma, or urine. It is an "open" system, which can use a variety of commercially manufactured reagents, such as, but not limited to Synermed's Reagents for Albumin, ALT, AST, ALP, Amylase, Calcium, CO2, Cholesterol, Creatinine, CK, Glucose, GGT, LDH, Maqnesium, Phosphorus, Total Protein, Triglycerides, Urea Nitrogen, Total Bilirubin, Direct Bilirubin, HDL Cholesterol, UBIC, Iron, Chloride, and Uric Acid as shown in 510(k) K971491 using the ANALETTE under Synermed's name IR 200

    Device Description

    An in vitro diagnostic automated clinical chemistry analyzer for the analysis of analytes in solution.

    AI/ML Overview

    The provided text is a 510(k) premarket notification summary and the FDA's response letter for the PRECISION SYSTEMS ANALETTE CHEMISTRY ANALYZER. It establishes "substantial equivalence" to a predicate device, the Synermed IR® 200.

    However, the document does not contain specific acceptance criteria, detailed study designs, or reported device performance metrics in the format requested. The "Performance" section within the Summary of Safety and Effectiveness only states: "Substantially equivalence was established in comparative studies. It was concluded from these results that this product is safe and effective." This is a general statement, not a detailed report of performance against quantitative criteria.

    The information requested in the prompt (sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, training set details, etc.) is typically found in the full 510(k) submission, not in this public summary document. The summary only attests that such studies were performed and deemed sufficient to show substantial equivalence.

    Therefore, many of the requested fields cannot be filled from the provided text.

    Here's a breakdown of what can be extracted and what cannot:

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

    Acceptance CriteriaReported Device Performance
    Not specified in the provided document. The document only states that "Substantially equivalence was established in comparative studies," implying that the device's performance was comparable to the predicate device, Synermed IR® 200, across various analytes. Specific quantitative criteria and performance values are not detailed.Not specified in the provided document. The document does not provide specific metrics like accuracy, precision, sensitivity, or specificity. It only states that the device was found to be "safe and effective" and "substantially equivalent" to the predicate.

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

    • Test Set Sample Size: Not specified in the provided document.
    • Data Provenance (e.g., country of origin, retrospective/prospective): Not specified in the provided document. It refers generally to "comparative studies" but provides no details on their design or origin.

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

    • Not applicable/Not specified. This device is an automated clinical chemistry analyzer. The "ground truth" for chemical measurements would typically be established through reference methods or certified standards, not expert reader consensus. The document does not mention experts establishing a ground truth for a test set.

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

    • Not applicable/Not specified. Adjudication methods like 2+1 or 3+1 are relevant for subjective interpretations (e.g., image reading), not for automated chemical analyzers where results are quantitative.

    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. The device is a standalone automated clinical chemistry analyzer, not an AI-assisted diagnostic tool for human readers. Such a study would not be relevant for this type of device.

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

    • Yes, implicitly. The ANALETTE™ is described as an "automated clinical chemistry analyzer for the analysis of analytes in solution." Its performance is inherently standalone for quantitative measurements. The "comparative studies" mentioned would have evaluated its direct measurements against a predicate device.

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

    • Implied Reference Methods/Standards: For an automated clinical chemistry analyzer, the ground truth would typically be established by validated reference methods, certified reference materials, or comparison to results from highly accurate lab instruments. The document does not explicitly state the method, but this is the standard for such devices.

    8. The sample size for the training set

    • Not applicable/Not specified. This device is a traditional automated chemistry analyzer, not an AI/ML device that requires a "training set" in the machine learning sense. Its operation is based on established chemical principles and pre-programmed algorithms for measurement and calculation.

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

    • Not applicable. As noted above, this is not an AI/ML device that uses a "training set."

    Intended Use

    The ILab 600 is an automated, random access clinical chemistry analyzer which uses analytical techniques (photometry and potentiometry) for the in vitro quantitation of analytes found in physiological fluids such as serum, plasma, urine and cerebrospinal fluid. The results of the measurements are used as medical diagnostic tools.

    Device Description

    The ILab 600 is an automated, random access clinical chemistry analyzer which uses analytical techniques (photometry and potentiometry) for the in virro quantitation of analytes found in physiological fluids such as serum, plasma, urine and cerebrospinal fluid. The results of the measurements are used as medical diagnostic tools.

    AI/ML Overview

    The ILab 600 Clinical Chemistry System is an automated, random access clinical chemistry analyzer that quantifies analytes in physiological fluids using photometry and potentiometry. The device was found substantially equivalent to the ILab 900/1800 Clinical Chemistry System (K932467, K943595) and IL Test assays (K943366, K952646, K943367, K952647).

    1. Acceptance Criteria and Reported Device Performance

    The acceptance criteria for the ILab 600 are implicit in its claim of substantial equivalence to the predicate device, the ILab 900. This means the performance of the ILab 600 must be "statistically similar" to that of the ILab 900 across various analytes and sample types (serum, urine, cerebrospinal fluid).

    The reported device performance is demonstrated through method comparison studies and precision studies.

    Precision Studies (ILab 600):

    • Serum Samples: Two levels of serum samples (three for Cholesterol) were tested in triplicate twice a day for 10 days (n=60 total). The Total %CV for most analytes was generally low, indicating good precision. For example:
      • Albumin: Level 1 (1.79%), Level 2 (1.08%)
      • ALT/GPT: Level 1 (1.26%), Level 2 (0.99%)
      • Cholesterol: Level 1 (2.11%), Level 2 (1.35%), Level 3 (1.37%)
      • ISE Sodium: Level 1 (0.94%), Level 2 (0.67%)
    • Urine Samples: Two levels of urine samples were tested in triplicate twice a day for 10 days (n=60 total). Similar to serum, Total %CV remained low:
      • Amylase: Level 1 (2.56%), Level 2 (2.02%)
      • Creatinine: Level 1 (2.11%), Level 2 (1.73%)
      • ISE Sodium: Level 1 (1.13%), Level 2 (0.65%)
    • Cerebrospinal Fluid Samples: Two levels of CSF samples were tested using IL Test Glucose Oxidase in triplicate twice a day for 5 days (n=30 total).
      • Glucose Oxidase: Level 1 (1.49%), Level 2 (0.98%)

    The studies conclude that the ILab 600 and ILab 900 are "statistically similar" for the tests evaluated. The precision studies demonstrate acceptable levels of reproducibility based on the reported Coefficient of Variation (%CV) values for within-run, among-run, among-day, and total precision. No specific numerical thresholds for acceptance criteria were explicitly stated, but the robust statistical similarity and low %CV values imply the device meets the necessary performance standards for clinical use.

    2. Sample Sizes and Data Provenance

    • Test Set (Method Comparison):

      • Serum Samples: Sample sizes ranged from a minimum of 64 (Lipase) to a maximum of 137 (Glucose Oxidase).
      • Urine Samples: Sample sizes ranged from 49 (ISE Potassium and Sodium) to 95 (Glucose Hexokinase).
      • Cerebrospinal Fluid Samples: Sample size was 20 (Glucose Oxidase).
      • Data Provenance: The document does not specify the country of origin of the data or whether it was retrospective or prospective.
    • Test Set (Precision Studies):

      • Serum Samples: n=60 for most analytes (triplicate measurements, twice a day, for 10 days). Cholesterol used n=60 across three levels.
      • Urine Samples: n=60 for all analytes (triplicate measurements, twice a day, for 10 days).
      • Cerebrospinal Fluid Samples: n=30 for Glucose Oxidase (triplicate measurements, twice a day, for 5 days).
      • Data Provenance: The document does not specify the country of origin of the data or whether it was retrospective or prospective.

    3. Number of Experts and Qualifications for Ground Truth

    The document pertains to the performance characteristics of a clinical chemistry analyzer, which measures quantitative values of analytes. The "ground truth" in this context refers to the actual concentration of the analytes in the samples. Clinical chemistry analyzer performance is typically evaluated by comparing results to a reference method (in this case, the predicate device ILab 900) or by using certified reference materials with known concentrations. Therefore, expert interpretation or consensus, as might be used in image-based diagnostic AI, is not applicable here. No mention of human experts defining "ground truth" is provided or expected.

    4. Adjudication Method

    Not applicable. As described in point 3, this is a quantitative measurement device, not an interpretation task requiring adjudication of expert opinions.

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

    Not applicable. The device is a clinical chemistry analyzer, not an AI system assisting human readers in diagnostic interpretation. The study evaluates the analyzer's performance directly against a predicate device and for precision, not the human reader's effectiveness with or without AI.

    6. Standalone Performance Study

    Yes, standalone performance was done.

    • Method Comparison Studies: The performance of the ILab 600 was compared directly to that of the ILab 900 (predicate device). This is a standalone comparison of the new device against an established one.
    • Precision Studies: The precision of the ILab 600 was evaluated independently, measuring its reproducibility across different runs and days. This is also a standalone performance evaluation of the device itself.

    7. Type of Ground Truth Used

    The ground truth used for these studies is the quantitative analytical result obtained from the predicate device (ILab 900) for method comparison studies, and the inherent, measured concentration within the biological samples for precision studies. This is a form of reference method comparison or analytical accuracy assessment, rather than pathology, expert consensus, or outcomes data, which are typically associated with qualitative or interpretative diagnostics. For precision, the ground truth is implicitly the true, stable concentration in the control/patient samples being repeatedly measured.

    8. Sample Size for the Training Set

    Not applicable. The ILab 600 is a clinical chemistry analyzer, which operates based on established chemical and photometric/potentiometric principles and internal calibration curves. It is not an AI/ML device that requires a "training set" in the sense of supervised learning. Its analytical methods are pre-programmed and validated, not learned from data in the way a machine learning algorithm would be.

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

    Not applicable, as there is no "training set" for this type of device. The device's operational parameters and calibration are established through engineering design and standard laboratory calibration procedures, not through a data-driven training process.
