The provided text does not contain specific acceptance criteria or detailed performance data from a study that would allow for a direct numerical comparison in a table. The document is a 510(k) summary and approval letter, stating that performance studies were conducted and the device was found substantially equivalent to predicate devices. However, it does not provide the raw performance data, acceptance thresholds, or detailed methodology of these studies.
Therefore, many of the requested fields cannot be filled with specific information from the provided document.
Here's an attempt to answer based on the available information, with clear indications where information is not provided:
Acceptance Criteria and Device Performance
1. Table of Acceptance Criteria and Reported Device Performance
| Performance Metric | Acceptance Criteria (Not explicitly stated numerically in document) | Reported Device Performance (Summary statement only, no specific values) |
|---|---|---|
| Accuracy (vs. predicate devices) | (Not explicitly stated numerically, implied to be "substantially equivalent") | "The studies demonstrated that the blood lactate results were substantially equivalent to the current methods for blood lactate measurements." |
| Equivalence (to laboratory methods) | (Not explicitly stated numerically) | "It is intended to provide plasma equivalent results to laboratory methods." |
| Precision/Reproducibility | (Not provided) | (Not provided) |
| Linearity | (Not provided, though linearity solutions are mentioned for checking) | (Not provided) |
| Interference | (Not provided) | (Not provided) |
| Measuring Range | (Not provided) | (Not provided) |
| Time to Result | (Not provided, though "within 13 seconds" is mentioned for both new and predicate device) | "Each utilizes a test strip that is inserted into a meter for results within 13 seconds." |
2. Sample size used for the test set and the data provenance
- Sample Size for Test Set: Not provided. The document mentions "Laboratory and clinical testing was performed" but does not specify the number of samples or patients included in these studies.
- Data Provenance: Not provided specific details. The studies were described as "Laboratory and clinical testing," implying data collected for the purpose of this submission. The country of origin is not specified, but the submitter is a U.S. company. It's likely prospective data collected for the purpose of the 510(k) submission, given the nature of performance studies for new devices, but this is an inference.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not provided. The document states "substantially equivalent to the current methods for blood lactate measurements" and "plasma equivalent results to laboratory methods," implying comparison to established methods or gold standards, but the process of establishing ground truth for the specific test set is not detailed.
4. Adjudication method for the test set
- Not provided. Given that the ground truth establishment method is not described, the adjudication method is also not mentioned.
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 a medical device for quantitative determination of lactate in whole blood, not an imaging or diagnostic AI device that involves human reader interpretation. Therefore, an MRMC study is not relevant to this type of device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- The device itself is a standalone system (meter and test strips) that provides a quantitative lactate reading. The performance studies described would inherently be standalone, assessing the device's ability to measure lactate accurately. There isn't a separate "algorithm only" component beyond the device's inherent operation.
7. The type of ground truth used
- The ground truth would implicitly be reference laboratory methods for lactate measurement, as the device aims to provide "plasma equivalent results to laboratory methods" and demonstrate "substantial equivalence to the current methods for blood lactate measurements."
8. The sample size for the training set
- Not applicable/Not provided. This device is a measurement system (meter and test strips), not a machine learning or AI-based diagnostic tool that typically involves a distinct "training set" for model development in the same way.

There are two levels of Nova Max Plus Glucose and ß-Ketone Control Solutions (Mid and High).
Nova Max Plus Glucose and ß-Ketone Control Solutions are for in vitro diagnostic use ONLY (for testing outside the body).
Nova Max Plus Glucose and β-Ketone Control Solutions are intended for use with the Nova Max Family of Monitors (Nova Max, Nova Max Plus, and Nova Max Link), BD Logic and Paradigm Link Morr yours, Nova Max Glucose Test Strips, and Nova Max Plus Ketone Test Strips as a quality control check to verify the accuracy of blood Glucose and fl-Ketone test results. There are two levels of Nova Max Plucose and B-Ketone Control Solutions (Mid and High).
Nova Max Plus Glucose and B-Ketone Control Solutions are for in vitro diagnostic use ONLY (for testing outside the body).
Here's an analysis of the provided text, focusing on the acceptance criteria and study information for the Nova Max Plus Glucose and β-Ketone Control Solutions.
The provided document describes a 510(k) submission for Nova Max Plus Glucose and β-Ketone Control Solutions, a Class I medical device (quality control material). As such, the information typically provided for more complex Class II or Class III devices regarding clinical trials, extensive performance metrics, and human reader studies is not applicable or present in this type of submission for a control solution.
The acceptance criteria here refer to the product demonstrating substantial equivalence to predicate devices. The study conducted primarily focuses on bench testing to support this claim, rather than clinical efficacy or diagnostic accuracy in patients.
Here's a breakdown of the requested information based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
Given the nature of a quality control solution and a 510(k) submission for a Class I device, "acceptance criteria" here relate to demonstrating that the new control solutions perform comparably to previously cleared predicate device components and are safe and effective for their intended use. The performance is assessed through laboratory studies.
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Pertains to control solutions for glucose and β-ketone: | All studies were performed, and results support the conclusion of substantial equivalence: |
| 1. Functional equivalency to predicate device components | The proposed Nova Max Plus Glucose and β-Ketone Control solutions use the same fundamental scientific technology and have the same intended use as the previously cleared predicate device components: Nova Max Plus Blood Glucose and β-Ketone Monitor System (K091547) and Nova Max Blood Glucose Monitor (K070255). |
| 2. Stability of control solutions | Stability studies were performed. (Specific results or duration not detailed in this summary). |
| 3. Reproducibility/Accuracy in relevant test systems | Averages in equivalency studies were performed. (Specific results or metrics not detailed, but imply comparison to expected values or predicate performance). The device measures Glucose and β-Ketone electrochemically, where the magnitude of current is proportional to the amount of analyte, providing a quantitative measure in control solutions. |
| 4. No new concerns for safety and effectiveness | Results of laboratory testing demonstrate that the performance of the Nova Max Plus Glucose and β-Ketone Control Solutions is "comparable to the performance of the previously cleared predicate devices." The device utilizes the same fundamental scientific technology and has the same intended use. "There are no new concerns for safety and effectiveness that have been shown through testing." This implies that testing did not reveal any unexpected adverse performance or safety issues compared to predicates. |
| 5. Adherence to general controls and regulatory requirements | The device is classified as Class I (21 CFR 862.1660 and 862.1435) with product codes JJX, JIN. The FDA's substantial equivalence determination implies compliance with necessary general controls (annual registration, listing, good manufacturing practice, labeling, prohibitions against misbranding and adulteration). |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: The document does not specify a numerical sample size for the "test set." It broadly refers to "stability studies" and "averages in equivalency studies" being performed in the laboratory. For a control solution, the "test set" would refer to the batches of control solution produced and tested, as well as the number of measurements taken. This detail is not provided.
- Data Provenance: The studies were conducted "in the laboratory." Given the submitter's address (Waltham, MA, U.S.A.) and the context of a U.S. FDA 510(k) submission, the data is presumably derived from retrospective internal laboratory testing conducted by Nova Biomedical Corporation in the U.S.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Number of Experts & Qualifications: This category is not applicable in the traditional sense for this device. For quality control solutions, "ground truth" is typically established by certified reference materials, analytical chemistry methods, or the manufacturing specifications and target values for the control. The document refers to the proposed solutions being for "in vitro diagnostic use ONLY." The "averages in equivalency studies" would likely compare the control solutions' measured values to these pre-defined target values or to the performance of predicate controls, as determined by laboratory experts, not clinical experts for diagnostic accuracy. No specific number or qualifications of experts for "ground truth" are mentioned.
4. Adjudication Method for the Test Set
- Adjudication Method: This concept is generally not applicable for a quality control solution. Adjudication methods (like 2+1 or 3+1) are used for resolving discrepancies in expert interpretations (e.g., radiologists reading images). Here, "performance studies" would involve comparing quantitative measurements against established norms or predicate device performance, which is a direct measurement and comparison rather than a subjective interpretation 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
- MRMC Study: No, an MRMC comparative effectiveness study was not done. This type of study (comparing human readers with and without AI assistance) is relevant for diagnostic imaging or interpretation devices, particularly those involving AI. The device in question is a quality control solution, not an AI-powered diagnostic tool.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Standalone Performance: This concept is not applicable to this device. A standalone (algorithm-only) performance is relevant for AI or automated diagnostic algorithms. The Nova Max Plus Glucose and β-Ketone Control Solutions are chemical solutions used to verify the accuracy of a monitor system; they do not have an "algorithm-only" performance in the way an AI diagnostic tool would. Their performance is inherent in their chemical composition and stability when measured by the intended monitor.
7. The Type of Ground Truth Used
- Type of Ground Truth: The ground-truth for quality control solutions is typically based on certified reference values, analytical standards, or established manufacturing targets for the glucose and β-ketone concentrations. The document implies that the device's performance, as measured by the monitor, is compared to these predetermined values or the performance of predicate controls, which represent the "ground truth" for what the control solution should measure. The text mentions "averages in equivalency studies," which would rely on such established truth.
8. The Sample Size for the Training Set
- Sample Size for Training Set: This is not applicable. This device is a quality control solution. It is manufactured, not "trained" in the context of machine learning or AI. Performance studies for control solutions involve batch testing, stability testing, and equivalency testing, but not a "training set" like an algorithm would require.
9. How the Ground Truth for the Training Set was Established
- How Ground Truth for Training Set was Established: This is not applicable as there is no "training set" for a quality control solution.

- Nova Max Plus B-Ketone Test Strips
- Nova Max Plus B-Ketone Control Solutions (Levels 1,2 and 3)
The provided text is a 510(k) summary for the Nova Max Plus Blood Glucose and B-Ketone Monitoring System. Medical device 510(k) summaries, especially for in vitro diagnostic (IVD) devices like this one, typically don't include the detailed statistical acceptance criteria or the full study reports. Instead, they focus on demonstrating substantial equivalence to a predicate device.
However, I can extract the information that is present and highlight what is not explicitly stated in this type of document, but would typically be part of the full submission.
Here's an analysis based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state specific statistical acceptance criteria (e.g., % within +/- X mg/dL or % within +/- Y%). It states the general conclusion that the device "performs as intended" and "can produce results that are substantially equivalent to results obtained on the predicate devices."
For blood glucose meters, typical acceptance criteria often align with ISO 15197 for accuracy, which specifies standards like:
- ≥95% of results for glucose concentrations < 75 mg/dL differ by no more than ± 15 mg/dL from the reference measurement.
- ≥95% of results for glucose concentrations ≥ 75 mg/dL differ by no more than ± 20% from the reference measurement.
For β-ketone meters, similar accuracy criteria would be applied.
Since the specific criteria and detailed performance statistics (e.g., bias, precision, linearity over a range) are not provided in this summary, a table cannot be fully populated. The document only offers a high-level summary of the performance.
2. Sample Size Used for the Test Set and Data Provenance
The document states: "The performance of the Nova Max Plus Blood Glucose and B-Ketone Monitoring System was studied in the laboratory and in clinical settings by healthcare professionals and lay users."
- Sample Size: Not explicitly stated. This would be detailed in the full performance study report within the 510(k) submission.
- Data Provenance: The studies were conducted in "the laboratory and in clinical settings" by "healthcare professionals and lay users." The country of origin is not specified, but Nova Biomedical Corporation is a U.S. company, suggesting the studies likely occurred in the U.S. The studies are implicit retrospective in the sense that they are evaluating a device that has already been developed and tested, but data collection would be prospective.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications
- Number of Experts/Reference Methods: Not explicitly stated. For IVD devices, "ground truth" (or reference method) for glucose and β-ketone is typically established using a high-precision laboratory analyzer (e.g., a YSI STAT PLUS Glucose & Lactate Analyzer for glucose, and a specific enzymatic method for β-ketone), rather than human experts reviewing images or clinical cases. These reference methods are themselves subject to strict quality control and calibration.
- Qualifications of Experts (if applicable): Not applicable in the traditional sense of human readers. The "experts" are the validated laboratory reference instruments and the trained personnel operating them according to standard protocols.
4. Adjudication Method for the Test Set
- Not applicable for this type of IVD device where ground truth is established by a reference laboratory method. Adjudication methods like 2+1 or 3+1 are typically used in imaging studies where human readers interpret data, and discrepancies need to be resolved.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- No, an MRMC study was not done. This type of study assesses how AI assistance impacts human reader performance (e.g., radiologists reading X-rays). For a blood glucose and ketone monitoring system, the "reader" is essentially the device itself, and its performance is compared directly to a reference method, not to how it aids human interpretation of complex data.
6. Standalone Performance Study
- Yes, a standalone study was done. The entire "Performance Studies" section describes the evaluation of the device as a standalone system. The statement, "The studies demonstrated that lay users can obtain blood glucose and blood ß-Ketone results that are substantially equivalent to the current methods for blood glucose and blood ß-ketone measurements," directly refers to the device's independent performance.
7. Type of Ground Truth Used
- Reference Laboratory Methods: The ground truth for both glucose and β-ketonetest results would be established by highly accurate and precise laboratory reference instruments. The text mentions "current methods for blood glucose and blood ß-ketone measurements" and that the "Glucose Monitor is calibrated to provide plasma equivalent results to laboratory methods," strongly implying the use of such reference methods.
8. Sample Size for the Training Set
- Not Applicable/Not Explicitly Stated. For a traditional electrochemical blood glucose/ketone meter, there isn't a "training set" in the sense of machine learning algorithms that require vast amounts of data to learn patterns. The device's calibration curve and algorithms are developed through R&D and then validated. If any specific data were used for initial calibration curve development, that information is not provided here.
9. How Ground Truth for the Training Set Was Established
- Not Applicable/Not Explicitly Stated. As mentioned above, a "training set" with established ground truth is not typically relevant for this type of IVD device in the same way it is for AI/ML-driven devices. Device calibration and algorithm development would rely on controlled solutions and known concentrations, not a "ground truth" derived from patient samples with expert consensus.

Not Found
Here's the analysis of the provided text regarding the Nova StatSensor Creatinine Hospital Meter, focusing on acceptance criteria and study details.
Important Note: The provided document is an FDA 510(k) clearance letter and an Indications for Use statement. It does not contain the detailed study write-up that would typically include acceptance criteria and specific performance data. Therefore, I can only extract information that is explicitly stated or can be reasonably inferred from this type of regulatory document. Many of the requested details (sample sizes, expert qualifications, adjudication methods, MRMC studies, training set details) are not present in this document.
Acceptance Criteria and Device Performance Study Analysis
Based on the provided documents (FDA 510(k) clearance letter K070068 and Indications for Use), the Nova StatSensor Creatinine Hospital Meter is cleared for marketing as it has been deemed "substantially equivalent" to legally marketed predicate devices. This indicates that the device met the performance requirements necessary to demonstrate this substantial equivalence. However, the exact numerical acceptance criteria and the detailed study design proving those criteria are not present in these documents.
Missing Information: A typical detailed study report would include specific numerical targets for accuracy, precision, linearity, etc., and the results obtained against those targets. This document only confirms that such testing must have occurred to achieve 510(k) clearance.
1. Table of Acceptance Criteria and Reported Device Performance
| Performance Metric | Acceptance Criteria (from predicate/general regulatory standards) | Reported Device Performance (as inferred from 510(k) clearance) |
|---|---|---|
| Accuracy / Bias | Must be demonstrably equivalent to a legally marketed predicate device for creatinine measurement in whole blood. | Deemed substantially equivalent to predicate devices; performs with acceptable accuracy for its intended use (quantitative measurement of creatinine in capillary, venous, and arterial whole blood, providing plasma equivalent results). |
| Precision | Must be within acceptable limits for a quantitative creatinine assay. | Achieved sufficient precision to demonstrate substantial equivalence. |
| Linearity | Must demonstrate linearity across the stated measurement range. | Linearity kit solutions are available, implying successful linearity testing across 5 levels. |
| Interfering Substances | (Not specified in document, but generally required) Minimal interference from common endogenous and exogenous substances. | Implied to be acceptable based on 510(k) clearance. |
| Reproducibility | (Not specified in document, but generally required) Consistent results across different operators, lots, and instruments. | Implied to be acceptable based on 510(k) clearance. |
| Calibrated to Plasma Equivalency | Must provide plasma equivalent results. | Explicitly stated: "The Creatinine Meter is calibrated to provide plasma equivalent results to laboratory methods." |
(Note: The "Acceptance Criteria" column is inferred from the general requirements for 510(k) cleared IVD devices and the nature of the predicate determination. The "Reported Device Performance" column states what the FDA's clearance implies, rather than specific numerical outcomes, as these are not provided.)
2. Sample Size Used for the Test Set and the Data Provenance
- Sample Size (Test Set): Not specified in the provided documents.
- Data Provenance: Not specified in the provided documents (e.g., country of origin, retrospective or prospective). Safety and effectiveness data, likely gathered prospectively from clinical or laboratory studies in the US or other regions, would have been submitted to the FDA as part of the 510(k) application.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
- Number of Experts: Not specified.
- Qualifications of Experts: Not specified.
- For an in vitro diagnostic device measuring a chemical analyte like creatinine, the "ground truth" would typically be established by a reference method run by trained laboratory personnel in a CLIA-certified or equivalent laboratory, not necessarily "experts" in the sense of clinicians reviewing images, but rather highly skilled laboratory technicians and clinical chemists.
4. Adjudication Method for the Test Set
- Adjudication Method: Not specified. This is generally not applicable in the same way for quantitative chemical assays as it would be for subjective interpretations (e.g., radiology reads). The "ground truth" for a chemical assay is typically a quantitative result from a reference method.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
-
MRMC Study: No, an MRMC study is not applicable for this type of device. MRMC studies are used for devices that assist human interpretation of diagnostic images (e.g., radiologists interpreting X-rays or MRI scans). The Nova StatSensor Creatinine Hospital Meter is a quantitative assay device; it measures a biochemical marker directly, rather than assisting human readers in interpreting complex data.
-
Effect Size of Human Readers Improvement: Not applicable, as no MRMC study was performed or is relevant for this device type.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
- Standalone Performance Study: Yes, the performance testing for an in vitro diagnostic device like this is inherently "standalone" in the sense that the device measures creatinine directly without human interpretive intervention. The performance characteristics (accuracy, precision, linearity, etc.) are evaluated based on the device's output compared to a reference method. There isn't an "algorithm" in the same sense as an AI image interpretation tool, but rather the electrochemical detection and calculation within the meter.
7. The Type of Ground Truth Used
- Ground Truth Type:
- Reference laboratory method: For quantitative diagnostic devices like this, the ground truth is established by a highly accurate and precise reference method for creatinine measurement (e.g., enzymatic or HPLC-based methods) performed in a clinical laboratory.
- The document states, "The Creatinine Meter is calibrated to provide plasma equivalent results to laboratory methods," indicating that established laboratory methods serve as the standard for comparison.
8. The Sample Size for the Training Set
- Sample Size (Training Set): Not specified in the provided documents.
- For a chemical assay device, "training set" doesn't apply in the same way as for machine learning algorithms. Instead, there would be internal development and verification studies using various samples to optimize the assay chemistry, electrode design, and instrument calibration before formal validation studies. The number of samples used in these internal studies is generally proprietary and not disclosed in regulatory summaries.
9. How the Ground Truth for the Training Set Was Established
- Ground Truth for Training Set: Not specified.
- Similar to the test set, during the development and calibration phases, the ground truth would have been established using reference laboratory methods for creatinine measurement on various samples to guide the optimization and calibration of the Nova StatSensor system.

This is a 510(k) premarket notification for a glucose meter and does not contain the detailed study information typically found in a clinical trial report or a scientific publication describing device performance and acceptance criteria. The provided document is an FDA clearance letter and an Indications for Use statement.
Therefore, I cannot provide a table of acceptance criteria and reported device performance or details about a study that proves the device meets specific criteria based solely on the provided text. The document states that the FDA reviewed the premarket notification and determined the device is "substantially equivalent" to legally marketed predicate devices, which is the basis for its clearance, rather than proof of meeting specific, pre-defined acceptance criteria in a detailed study report within this document.
For a glucose meter, acceptance criteria typically relate to accuracy (e.g., bias, precision, and agreement with a reference method as per ISO 15197 for point-of-care blood glucose monitoring systems) and other performance characteristics, but these specific criteria and the data to prove them are not in this clearance letter.
To answer your specific questions in the format requested, based only on the provided text, I can state:
-
Table of acceptance criteria and the reported device performance:
Not provided in this document. The document primarily concerns the FDA's substantial equivalence determination, not a detailed presentation of performance data against specific acceptance criteria. -
Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective):
Not provided in this document. -
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 or not provided. For a glucose meter, ground truth is typically established by laboratory reference methods (e.g., YSI 2300 STAT Plus Glucose & Lactate Analyzer), not expert readers. -
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
Not applicable or not provided. -
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 a glucose meter, not an AI-assisted diagnostic imaging device. -
If a standalone (i.e. algorithm only, without human-in-the-loop performance) was done:
A glucose meter inherently operates "standalone" in generating a quantitative reading. However, the details of its standalone performance testing (e.g., accuracy against a reference method) are not included in this document. -
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
While not explicitly stated in this document, for glucose meters, the ground truth is typically established using a high-precision laboratory reference method (e.g., hexokinase method on a central laboratory analyzer). -
The sample size for the training set:
Not applicable or not provided. This device is likely using established electrochemical principles; modern machine learning "training sets" are not typically used for this type of device in the same way they would be for an AI algorithm. -
How the ground truth for the training set was established:
Not applicable or not provided.
