CHOLESTEROL: Reagent kit intended for the quantitative determination of Cholesterol in human serum. Cholesterol measurements are used in the diagnosis and treatment of disorders involving excess cholesterol in the blood, of lipid and lipoprotein metabolism disorders.

HDL-Cholesterol: Reagent kit intended for the quantitative determination of high-density lipoprotein in human serum. Measurements are used in the diagnosis and treatment of lipid disorders mellitus), atherosclerosis, and various liver and renal diseases.

LDL-Cholesterol: Reagent kit intended for the quantitative determination of low-density lipoprotein in human serum. Lipoprotein measurements are used in the diagnosis and treatment of lipid disorders (such as diabetes mellitus), atherosclerosis, and various liver and renal diseases.

TRIGLYCERIDES: Reagent kit intended for the quantitative determination of triglycerides (neutral fat) in human serum. Measurements are used in the diagnosis and treatment of patients with diabetes mellitus, nephrosis, liver obstruction, other diseases involving lipid metabolism, or various endocrine disorders.

CHOLESTEROL: The Cholesterol Oxidase peroxidase (CHOD-PAP) enzymatic method is used. The cholesterol esterase enzyme catalyzes the hydrolysis of cholesterol and free fatty and free fatty acids. Free cholesterol, including that originally present in the sample, is then oxidized by the enzyme cholesterol oxidase (CHOD) to cholest-4-en-3-one, by using molecular oxygen as the electron acceptor and concurrently producing hydrogen peroxide (H2O2). The H2O2 produced is then used in a subsequent chromogenic oxidative coupling reaction, catalyzed by the enzyme peroxidase, in the presence of a redox indicator system, which leads to the formation of a colored compound, absorbing light at 550 nm. The increase in absorbance is directly proportional to the cholesterol concentration in the sample.

HDL-Cholesterol: The Accelerator Selective Detergent method is applied. The determination of HDL-Cholesterol is based on the following reactions: LDL, VLDL, and chylomicrons are neutralized by the combined action of the enzymes Cholesterol Oxidase, Peroxidase, accelerators and N,N-bis-(4-sulfobutyl)-m-toluidine-disodium (DSBmT). HDL remaining in the sample is disrupted by the action of a selective detergent and cholesterol is converted to △4 Cholestenone by the enzymatic action of Cholesterol Esterase and Cholesterol Oxidase, with the subsequent production of H2O2, which reacts with DSBmT and 4-aminoantipyrine in the presence of Peroxidase to a colored complex that absorbs light at 590 nm. The absorbance measured is proportional to the concentration of HDL-Cholesterol in the sample.

LDL-Cholesterol: The Selective Detergent method is applied. The method is in a two-reagent format and depends on the properties of a unique detergent. The first detergent solubilizes only the non-LDL lipoprotein particles. The cholesterol released is consumed by cholesterol esterase and cholesterol oxidase in a non-color forming reaction. The second detergent solubilizes the remaining LDL particles, and a chromogenic coupler allows for color formation. The enzyme reaction with LDL-Cholesterol in the presence of the coupler at 590 nm produces color that is proportional to the amount of LDL cholesterol present in the sample.

TRIGLYCERIDES: The enzymatic glycerol-3-phosphate-peroxidase (GPO-POD) method is used. The method enzymatically hydrolyzes by lipase to free fatty acids and glycerol is phosphorylated by adenosine triphosphate (ATP) with glycerokinase (GK) to produce glycerol-3-phosphate and adenosine diphosphate (ADP). Glycerol-3-phosphate-oxidase oxidizes glycerol-3-phosphate to dihydroxyacetone phosphate and H2O2. The catalytic action of peroxidase (POD) forms quinoneimine from H202, aminoantipyrine, and Dihydrate (N-Ethyl-N-(2hydroxy-3-sulfopropyl)-m-toluidine (TOOS). The absorption change at 550 nm is proportional to the triglycerides concentration in the sample.

The Cholesterol2 assay is used for the quantitation of cholesterol in human serum or plasma on the ARCHITECT c System. The Cholesterol2 assay is to be used as an aid in the diagnosis and treatment of disorders involving excess cholesterol in the blood and lipid and lipoprotein metabolism disorders.

The Cholesterol2 assay is an automated clinical chemistry assay for the quantitation of cholesterol in human serum or plasma on the ARCHITECT c System. Cholesterol esters are enzymatically hydrolyzed by cholesterol esterase to cholesterol and free fatty acids. Free cholesterol, including that originally present, is then oxidized by cholesterol oxidase to cholest-4-ene-3-one and hydrogen peroxide. The hydrogen peroxide oxidatively couples with N,N-Bis(4-sulfobutyl)-3-methylaniline (TODB) and 4-aminoantipyrine to form a chromophore (quinoneimine dye) which is quantitated at 604 nm.

The provided text describes the Abbott Cholesterol2 assay, an in vitro diagnostic device for quantifying cholesterol in human serum or plasma.

Here's an analysis of the acceptance criteria and study data:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state pre-defined acceptance criteria for each performance characteristic. Instead, it presents the results of various studies as proof of device performance. The table below summarizes the reported performance, which implicitly serves as the "met" criteria.

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

• Precision Study: 2 controls and 3 human serum panels were tested. Each sample was tested in duplicate, twice per day for 20 days. This means 80 measurements per sample (2 duplicates x 2 times/day x 20 days).
• Lower Limits of Measurement Study: n ≥ 60 replicates for LoB, LoD, and LoQ determinations. They used low-analyte level samples and zero-analyte samples.
• Linearity Study: The number of samples for the linearity study is not explicitly stated, but it covered the range of 5 to 748 mg/dL.
• Interference Studies: Each endogenous substance was tested at 2 analyte levels (approximately 150 mg/dL and 220 mg/dL). Exogenous substances were tested at various specified interferent levels. The number of samples for each interferent is not provided.
• Method Comparison Study: 138 serum samples were used.
• Tube Type Study: Samples were collected from a minimum of 40 donors.
• Dilution Verification: 8 human serum samples.

Data Provenance: The document does not specify the country of origin of the data or whether the studies were retrospective or prospective. Given the context of medical device regulatory submission, these are typically prospective studies conducted in a controlled laboratory environment. The "human serum panels" and "human serum samples" imply human-derived biological samples.

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)

This device is an in vitro diagnostic (IVD) chemistry assay. The concept of "experts establishing ground truth" as it applies to image interpretation or clinical diagnosis by medical professionals (like radiologists) does not directly apply here in the same way.

For IVDs like this, the "ground truth" or reference values are established through:

• Reference methods: The Cholesterol2 reagent is certified to be traceable to the National Reference System for cholesterol, against the Abell-Kendall reference method in a CDC-Certified Cholesterol Reference Method Laboratory Network (CRMLN). The Abell-Kendall method is considered the gold standard for cholesterol measurement.
• Analytically Validated Methods: For values outside the AMI but within the EMI, samples were "value assigned using the analytically validated method."
• Known concentrations: For studies like linearity, spiked samples with known concentrations are used.

Therefore, the "experts" are the methodologists and laboratory professionals overseeing and validating the reference methods and the analytical validation processes. No specific number or qualification of clinical experts (e.g., radiologists) is relevant for establishing the ground truth for a quantitative chemistry assay.

This is a standalone performance evaluation of the assay itself, demonstrating its analytical accuracy, precision, and robustness.

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

The concept of "adjudication" (e.g., 2+1, 3+1 where multiple human readers agree or have a tie-breaker by an expert) is not applicable to this type of quantitative diagnostic assay. The results are numerical values generated by the automated instrument and reagents. Deviations or discrepancies would be resolved through re-testing, quality control, or investigation into instrument or reagent issues, rather than human expert adjudication of a "diagnosis."

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, an MRMC comparative effectiveness study was not done. This is an in vitro diagnostic assay, not an AI-powered diagnostic imaging device or an AI assistant for human readers. Its output is a quantitative measurement of cholesterol, not an interpretation that requires human "reading" or decision support.

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

Yes, a standalone performance evaluation of the device (Cholesterol2 assay on the ARCHITECT c8000 System) was done. The studies described (reportable interval, precision, lower limits of measurement, linearity, interference, method comparison, tube type, dilution verification) all evaluate the analytical performance of the assay and instrument directly, without human interpretation as part of the primary outcome measure. The output is a numerical concentration of cholesterol.

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

The ground truth used for this quantitative assay primarily relies on:

• Reference Methods: Specifically, the Abell-Kendall reference method, which is considered the gold standard for cholesterol measurement and is used in CDC-Certified Cholesterol Reference Method Laboratory Networks (CRMLN). The device's traceability to this method is explicitly stated.
• Analytically Validated Methods: For verifying values in the extended measuring interval.
• Known Spiked Concentrations: For studies such as linearity and dilution verification, where samples are prepared with precisely known concentrations.

This is an analytical ground truth, not a clinical ground truth derived from pathology or patient outcomes.

8. The sample size for the training set

This document does not describe a typical "training set" in the context of machine learning or AI. This is a chemistry assay that uses reagents and enzymatic reactions, not an algorithm that is "trained" on data. Therefore, the concept of a training set as used in AI development is not applicable here. The assay's analytical characteristics are determined through standard laboratory validation studies.

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

As explained above, there is no "training set" in the AI sense for this device. The analytical accuracy and reliability are established through comparisons to certified reference methods and known standard concentrations, as described in point 7.

The provided text describes the FORA ADVANCED GD40 Glucose, β-Ketone and Cholesterol Monitoring System, a device for measuring glucose, beta-hydroxybutyrate (β-ketone), and cholesterol in fresh capillary whole blood. It is a 510(k) summary, therefore, it focuses on demonstrating substantial equivalence to predicate devices rather than a detailed clinical study for a novel device.

Based on the provided information, here's a breakdown of the acceptance criteria and the study conducted to prove the device meets these criteria:

Key Takeaway: The document primarily focuses on non-clinical and clinical "studies" to demonstrate performance characteristics and compare them to predicate devices, rather than a single, large-scale comparative effectiveness study with human readers (MRMC). The "acceptance criteria" are implied by the performance characteristics tested and similarity to the predicate.

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are not explicitly stated as numerical targets in a table within the provided text. Instead, the document discusses "performance criteria were met" and that the device "met design specifications and requirements." The "acceptance criteria" are implied by meeting the established ranges and performance levels comparable to the predicate devices.

However, the "performance" is reported through the summary of testing. Since this is a 510(k) submission, the primary "performance" shown is that the device is substantially equivalent to the predicate devices. The listed similarities and differences in characteristics serve as the de facto "reported device performance."

1. Table of Acceptance Criteria and Reported Device Performance

The document doesn't explicitly state formal "acceptance criteria" values in a table. However, the linearity, precision, and bias data are direct measures of performance against presumed internal or regulatory benchmarks for acceptable accuracy and precision in cholesterol measurement devices. We will infer the reported device performance from the study results presented.

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

• Sample Size: A total of 369 patients were recruited for the clinical study.
• Data Provenance: The study was conducted at three point-of-care (POC) sites located in different geographical locations. It is a prospective clinical study as patients were recruited and tested specifically for this study. The country of origin is not explicitly stated, but given the FDA submission, it can be inferred to be compliant with US regulatory standards, likely involving data collected within the US or under equivalent standards.

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

The document does not explicitly state the number of experts. However, it mentions:

• "For professional use, patient blood was collected from fingertip and venous blood draws. Capillary blood samples from fingertip were tested at clinical sites by professionals. Venous blood samples were tested at a laboratory using an FDA cleared method."
• "The plasma concentration was confirmed by the reference method."

This implies that trained "professionals" (likely medical technicians or laboratory personnel) performed the official comparative testing, and an FDA-cleared reference method was used to establish the ground truth. No specific number or qualification (e.g., "radiologist with 10 years of experience") for these "professionals" is given beyond their professional role in clinical sites or laboratories.

4. Adjudication Method for the Test Set

The document does not describe a formal adjudication method (like 2+1 or 3+1). The ground truth was established by comparing the device's results to an "FDA cleared method" and a "reference method" in laboratory settings. This suggests direct quantitative comparison rather than a consensus-based adjudication process typical for qualitative or image-based diagnostics.

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

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not explicitly mentioned or performed in the context of improving human reader performance with AI assistance. This study focuses on the device's standalone analytical performance compared to a reference method, and also includes layperson use, not assisted reading by human experts.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

Yes, a standalone performance study was done for the device. The entire clinical study, comparing the Mission Cholesterol Monitoring System's measurements against a reference method, evaluates the algorithm's performance. Both professional operators and laypersons used the device independently to obtain results, which were then compared to the established ground truth.

7. The Type of Ground Truth Used

The ground truth for the clinical study was established by comparing the device's results to an FDA cleared method and a reference method (for plasma concentration).

8. The Sample Size for the Training Set

The document does not provide information regarding a separate training set or its sample size. The studies described are for the validation of an already developed device.

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

Study Details

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

   • Precision (Repeatability & Intermediate Precision): 5 human serum pools and 2 control samples were used. Tested for 21 days with 4 replicates/day. Data provenance is not explicitly stated as country of origin, but implied to be from a laboratory setting (likely in the US or Germany, given Roche's locations). The nature of the study (analyzing human serum pools and controls) suggests prospective data collection for evaluating device performance.
   • Analytical Sensitivity (LoB, LoD, LoQ):
     • LoB: One analyte-free sample. Measured 10-fold in 6 runs over 3 days, per reagent lot (total 60 measurements per lot).
     • LoD: Five samples with low-analyte concentration. Measured two-fold in 6 runs over 3 days, per reagent lot (total 60 measurements per lot).
     • LoQ: A low-level sample set prepared by diluting 5 human serum samples. Tested in 5 replicates per sample on 5 days.
   • Linearity/Assay Reportable Range: Dilution series prepared using 1 serum pool and 1 plasma pool. The dilution series contained 11 concentrations for serum and 15 concentrations for plasma.
   • Endogenous Interferences: Two human serum pools spiked with HDL-Cholesterol and interfering substances.
   • Exogenous Interferences (Drugs): Two human serum sample pools.
   • Method Comparison to Predicate: 111 routine laboratory serum samples. Additionally, 4 samples spiked with high human serum HDL-Cholesterol and 1 sample diluted with 0.9% NaCl. Data provenance is not explicitly stated as country of origin, but implied to be from a laboratory setting. The use of "routine laboratory serum samples" suggests retrospective collection, though the spiking and dilution aspects are prospective for the study design.
   • Matrix Comparison: 38 paired samples (serum and plasma) from single donors.

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

   • For this type of in vitro diagnostic device (quantitative measurement of a biomarker), "ground truth" is typically established by reference methods or validated comparative methods, not by human expert consensus or clinical adjudication as would be seen in imaging diagnostics.
   • The predicate device (Ultra N-geneous HDL Cholesterol Reagent, K021316) serves as a comparative "ground truth" for the method comparison study. The precision, sensitivity, linearity, and interference studies establish the intrinsic performance properties of the device against predefined analytical standards (e.g., CLSI guidelines).
   • Therefore, the concept of "experts" as in "a radiologist with 10 years of experience" is not directly applicable here. The experts involved would be laboratory scientists, biochemists, and statisticians who designed and executed the studies according to CLSI guidelines and interpreted the analytical data.

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

   • Adjudication methods like 2+1 or 3+1 are typically used in clinical imaging studies where subjective interpretation is involved.
   • For this in vitro diagnostic device, measurements are quantitative, and "adjudication" is done through statistical analysis and adherence to predefined acceptance criteria based on established analytical guidelines (e.g., CLSI EP5-A3 for precision, CLSI EP17-A2 for detection limits, CLSI EP6-A for linearity). There is no "human adjudication" process for individual results as there would be for image interpretation.

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:

   • No, an MRMC comparative effectiveness study was not done. This type of study is relevant for imaging devices where human readers interpret medical images, and AI might assist or replace them. The HDL-Cholesterol Gen.4 is an in vitro diagnostic device that quantifies a substance in a laboratory sample; it does not involve human "readers" interpreting results in a subjective or visual manner that AI would enhance.

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

   • Yes, the performance evaluation reports are inherently demonstrating the "standalone" performance of the analytical algorithm/reagent system. The studies evaluate the device's ability to accurately and precisely measure HDL-cholesterol concentrations in samples, independent of further human interpretation beyond routine laboratory operation and quality control. The reported results (e.g., mean, SD, CV, regression equations) directly reflect the algorithm's performance.

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

   • Analytical Ground Truth: For the precision, sensitivity, linearity, and interference studies, the "ground truth" is based on the known concentrations of analytes in prepared samples (e.g., spiked samples, diluted samples, control materials) or the absence of analytes (blank samples), and performance is evaluated against established analytical standards and acceptable deviations.
   • Comparative Ground Truth: For the method comparison study, the predicate device (Ultra N-geneous HDL Cholesterol Reagent, K021316) served as the comparative "ground truth" or reference method for evaluating substantial equivalence. This is a common approach for 510(k) clearances.
   • No pathology or outcomes data was used for establishing the ground truth for device performance in this submission, as it's an analytical performance study for an IVD.

7. The sample size for the training set:

   • This document describes the pre-market notification (510(k)) studies for device validation, not the development or training of an AI algorithm. Therefore, there is no "training set" for an AI mentioned or implied in this submission. The device is a chemical reagent system, not an AI/ML independent medical device.

8. How the ground truth for the training set was established:

   • As noted above, no "training set" for an AI algorithm is described in this submission. The ground truth for the analytical studies described (e.g., precision, linearity) is based on the preparation of samples with known concentrations or comparative analysis against a validated predicate device, as per standard laboratory practice and CLSI guidelines.

This looks like a 510(k) summary for an in vitro diagnostic (IVD) device, specifically for a Direct HDL Cholesterol (HDL) test system. Since IVD devices, especially Class I, do not typically involve AI or machine learning components as described in the prompt's questions, many of the requested fields (such as "number of experts used to establish ground truth", "adjudication method", "MRMC study", "standalone performance", "training set size", and "how ground truth for training set was established") are not applicable.

However, I can extract the relevant information regarding acceptance criteria and performance from the document.

1. Table of Acceptance Criteria and Reported Device Performance:

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

• Precision/Reproducibility:
  • Control material and human serum samples: 80 determinations per control level/serum pool (2 replicates/run x 2 runs/day x 20 days).
  • Provenance: "unaltered human serum samples" and "control material." The documentation does not specify the country of origin of the human serum samples. The study design (testing over 20 non-consecutive days) suggests it's a prospective study for data collection, but the samples themselves could be retrospective.
• Linearity/Reportable Range:
  • Samples: 11 levels, each run in replicates of five.
  • Provenance: Low and high serum pool samples. Not specified for country of origin or retrospective/prospective.
• Detection Limit:
  • Samples: 240 determinations (4 low-level samples) for LoD.
  • Provenance: Not specified for country of origin or retrospective/prospective.
• Analytical Specificity (Interference):
  • Samples: Spiked samples at 34.8 mg/dL and 70 mg/dL HDL Cholesterol concentrations. The number of individual samples is not explicitly stated.
  • Provenance: Not specified for country of origin or retrospective/prospective.
• Method Comparison:
  • Patient Samples: 103 serum patient samples.
  • Provenance: Not specified for country of origin or retrospective/prospective.
• Matrix Comparison:
  • Patient Samples: 45 matched patient sample pairs (serum and lithium heparin plasma).
  • Provenance: Not specified for country of origin or retrospective/prospective.

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

• Not applicable as this is an in vitro diagnostic (IVD) device for quantitative biochemical analysis, not an AI/image-based diagnostic device requiring expert interpretation for ground truth. Ground truth is typically established by reference methods or validated laboratory measurements.

4. Adjudication Method for the Test Set:

• Not applicable for this type of IVD device.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance:

• Not applicable as this is an IVD device, not an AI-assisted diagnostic system involving human readers.

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

• This device is a standalone in the sense that its performance characteristics (precision, linearity, interference, method comparison) are evaluated for the device itself as an assay system. There is no "algorithm only" vs. "human-in-the-loop" distinction because it's a quantitative chemical assay.

7. The Type of Ground Truth Used:

• For precision, linearity, and detection limit: The "ground truth" is implied to be the actual concentration of HDL Cholesterol, which is determined by the preparation of controls, spiked samples, and dilutions, or by the inherent properties of the samples themselves, and measured by the device and predicate.
• For analytical specificity (interference): The ground truth is the presence/absence of interferents at specific concentrations and their impact on the HDL measurement.
• For method comparison: The "ground truth" for comparison is the measurement obtained from the predicate device (Randox Laboratories Ltd, Direct HDL Cholesterol reagent, K982341). This represents a legally marketed device against which equivalence is demonstrated.
• For matrix comparison: The ground truth for comparison is the measurement obtained from serum samples when comparing to plasma samples.

8. The Sample Size for the Training Set:

• Not applicable in the context of machine learning/AI where "training set" has a specific meaning. For an IVD, the development and optimization of the reagent formulation and assay parameters would be an analogous "training" phase, but it doesn't involve a distinct "training set" of patient data in the AI sense.

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

• Not applicable for the same reasons as above. The "ground truth" for developing the assay itself would be established through chemical principles, optimization experiments, and validation against known standards and reference materials.

Here's a breakdown of the acceptance criteria and study information for the Randox Laboratories Ltd. Cholesterol device, based on the provided FDA 510(k) summary:

1. Table of Acceptance Criteria and Reported Device Performance

The document doesn't explicitly state "acceptance criteria" for all tests in a single table, but rather presents the performance results of various analytical studies that demonstrate the device's capability. I've compiled the relevant performance data from the document into a table, noting the implicit acceptance measures (e.g., meeting CLSI guidelines, certain correlation coefficients, or imprecision percentages).

2. Sample Sizes and Data Provenance for the Test Set

• Precision/Reproducibility:
  • Controls: Not explicitly stated as "sample size" but data is reported for commercial control materials (717UE, 724UE, 952UN).
  • Patient Samples: 4 concentrations of unaltered human serum samples (3 diluted, 1 spiked for Linearity Pool, 1 Sensitivity Pool). Each sample run in 2 replicates per run, twice per day for 20 non-consecutive days, using 2 reagent lots on 2 RX Daytona plus systems.
  • Data Provenance: "unaltered human serum samples" implies human origin, likely retrospective for spiking/dilution. No country of origin is specified.
• Linearity/Assay Reportable Range:
  • Sample Size: 11 levels of samples covering the measuring range. Each level run in 5 replicates.
  • Data Provenance: "linearity samples" were prepared. Implies in-vitro prepared samples to cover the range, likely based on human serum/plasma.
• Detection Limit (LoD), Limit of Blank (LoB), Limit of Quantitation (LoQ):
  • Sample Size: LoD was based on 240 determinations with 4 low-level samples.
  • Data Provenance: Not specified, but generally prepared samples for low-level determination.
• Analytical Specificity (Interference):
  • Sample Size: Not explicitly stated for the number of interferent samples, but tested at Cholesterol concentrations of 150 mg/dl and 250 mg/dl for each interferent.
  • Data Provenance: Prepared samples spiked with interferents.

  • Sample Size (Potassium 2 EDTA): Minimum of 50 matched patient sample pairs (serum vs. potassium 2 EDTA plasma).
  • Data Provenance: "Patient samples were drawn in matched pairs". Retrospective from human subjects. No country of origin specified.

3. Number of Experts and Qualifications for Ground Truth for the Test Set

This device is an in vitro diagnostic (IVD) for quantitative measurement of cholesterol. The "ground truth" for such devices is established by precise laboratory reference methods or established commercially available controls and calibrators with known values.

• No "experts" in the sense of radiologists or pathologists establishing ground truth as would be the case for imaging devices.
• Ground truth is established by:
  • Reference materials (e.g., NIST 1952a for the calibrators, mentioned under traceability).
  • Established analytical methods used by the predicate device and in clinical laboratories.
  • CLSI guidelines for experimental design and data analysis.

4. Adjudication Method for the Test Set

Not applicable for this type of quantitative IVD device. Adjudication methods (like 2+1, 3+1) are typically used for qualitative or semi-quantitative assessments, especially in imaging or pathology, where human expert discrepancy resolution is needed. For quantitative chemical measurements, the ground truth is often numerical and objectively determined.

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

No. This is an in vitro diagnostic device for chemical analysis of cholesterol, not an imaging or qualitative assessment device involving human readers. Therefore, an MRMC study is not relevant.

6. Standalone (i.e., algorithm only without human-in-the-loop performance) Study

Yes, the entire performance evaluation presented is a standalone study of the device (Cholesterol assay on the RX Daytona plus system). The device performs the analytical measurement autonomously once the sample is loaded. The studies demonstrate the analytical performance of the device itself.

7. Type of Ground Truth Used

The ground truth for the performance studies is multi-faceted:

• Reference Materials: Randox Calibration Serum Level 3 is traceable to Cholesterol reference material NIST 1952a. This is a primary ground truth for calibration and accuracy.
• Predicate Device: For method comparison studies, the predicate device (Randox Cholesterol reagent, K923504) serves as a comparative ground truth, aiming to demonstrate substantial equivalence rather than absolute biological truth.
• CLSI Guidelines: The studies adhere to CLSI (Clinical and Laboratory Standards Institute) guidelines (EP5-A2 for precision, EP6-A for linearity, EP17-A2 for detection limits, EP9-A2 for method comparison), which represent an industry-accepted "ground truth" for how these analytical performance characteristics should be determined and evaluated.
• Prepared Samples: For linearity, sensitivity, detection limits, and interference, samples were prepared to known concentrations or spiked with known substances to create specific "ground truth" scenarios.

8. Sample Size for the Training Set

There is no mention of a "training set" in the context of machine learning or AI, as this device is a traditional in vitro diagnostic reagent system, not an AI/ML-based device.

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

Not applicable, as there is no training set for an AI/ML algorithm in this context.
