2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the numerical sample size for the test set used in the accuracy studies (clinical testing) or for the individual non-clinical tests.
- Data Provenance: The submitter is Apex Biotechnology Corp. in Hsinchu, Taiwan. The document does not explicitly state the country of origin of the clinical data or whether it was retrospective or prospective, but clinical studies are generally prospective for device clearance.
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 glucose and ketone monitoring systems, ground truth is typically established using a laboratory reference method (e.g., YSI analyzer) performed by trained laboratory personnel, rather than experts in the sense of radiologists.
4. Adjudication Method for the Test Set
This information is not provided in the document.
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. The MTM301 Blood Glucose and Ketone Monitoring System is a self-testing in vitro diagnostic device, not an AI-assisted diagnostic tool that would involve human readers or MRMC studies.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, the device operates as a standalone system. The clinical accuracy studies evaluate the algorithm's performance in measuring glucose and ketone in capillary whole blood. The system is intended for "self-testing outside the body (in vitro diagnostic use) by people with diabetes mellitus at home," indicating its standalone operational nature without professional human interpretation.
7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)
The document does not explicitly state the type of ground truth used, but for blood glucose and ketone monitoring systems, the ground truth is typically established using laboratory reference methods (e.g., a YSI analyzer for glucose, or a high-performance liquid chromatography (HPLC) method for ketones) on venous blood samples, against which the capillary blood measurements from the device are compared. This constitutes a highly accurate, quantitative ground truth.
8. The Sample Size for the Training Set
The document does not provide information about a "training set" sample size. For in vitro diagnostic devices like blood glucose meters, the development process typically involves internal calibration, optimization, and verification using various samples, but these are not usually referred to as a "training set" in the same way as machine learning models. The "clinical testing" described would be more analogous to an independent "test set" for performance evaluation.
9. How the Ground Truth for the Training Set Was Established
As noted above, the document does not refer to a "training set" in the context of establishing ground truth for machine learning. The ground truth for development and testing would generally follow standard laboratory reference methods.

Here's an analysis of the provided text, extracting information related to acceptance criteria and the study that proves the device meets them:
1. Table of Acceptance Criteria and Reported Device Performance:
The document provides information on the accuracy studies for both glucose and ketone measurements. The acceptance criteria for these are described in the device's previous clearances (K170267 for glucose and K182593 for ketone). While the exact numerical acceptance criteria are not explicitly stated within this specific 510(k) summary for this device (K201880), it notes that the systems used are the same as previously cleared products, implying they meet the previously established criteria. The reported performance is that the "Results demonstrate substantial equivalence to the predicate system."
Given the information available, a table would look like this:
| Measurement Type | Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|---|
| Blood Glucose | Performance criteria established in K170267 | Substantially equivalent to the predicate system (K091547) |
| Blood Ketone | Performance criteria established in K182593 | Substantially equivalent to the predicate system (K091547) |
| Ease of Use & Understanding (User Manual) | Not explicitly detailed for this 510(k), but assessed in clinical study | Substantially equivalent to the predicate system (K091547) |
2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size for Test Set: The document does not explicitly state the numerical sample size for the "accuracy studies for glucose and ketone" or the "evaluation of ease of use." It only mentions that these studies were "conducted with home users."
- Data Provenance: Not specified within this document. The submitter is from Hsinchu, Taiwan, but the location where the clinical studies were performed is not mentioned. It is prospective, as it involves human participants (home users) in a clinical study.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts:
This document does not specify the number or qualifications of experts used to establish the ground truth for the test set. For blood glucose and ketone monitoring systems, ground truth is typically established by comparative measurements against a laboratory reference method, not necessarily by expert consensus in the way a diagnostic imaging study might.
4. Adjudication Method for the Test Set:
Not applicable or specified. For glucose and ketone measurements, adjudication methods (like 2+1, 3+1) are typically used for qualitative or imaging-based assessments where human interpretation is involved. For quantitative measurements against a reference standard, direct comparison is the method.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. MRMC studies are typically used to evaluate the diagnostic performance of human readers, often comparing performance with and without AI assistance, particularly in imaging diagnostics. This device is a quantitative blood analyzer for self-testing, so this type of study is not relevant.
6. Standalone Performance (Algorithm Only Without Human-in-the-loop Performance):
Yes, a standalone performance study was done for the device itself. The "accuracy studies for glucose and ketone" assess the performance of the device (meter and test strips) in measuring blood glucose and ketone levels. While performed by "home users," the focus is on the device's ability to provide accurate readings, not on human interpretation of those readings.
7. Type of Ground Truth Used:
For the "accuracy studies for glucose and ketone," the ground truth would typically be established by a laboratory reference method. This is standard for quantitative diagnostic devices like blood glucose and ketone meters, where the device's readings are compared against a highly accurate and precise laboratory analyzer. The document states "accuracy studies," which implies comparison to a gold standard.
8. Sample Size for the Training Set:
The document does not provide information on the sample size for a training set. This is often not explicitly detailed for diagnostic devices that rely on established electrochemical biosensor technology, as opposed to devices employing complex machine learning or AI models that require extensive "training" data. The technology itself (Glucose Oxidase for glucose, $\beta$-hydroxybutyrate dehydrogenase for ketone) is well-understood and the "training" would have been part of the initial development and calibration of the test strips and meter, not necessarily a distinct "training set" in the context of AI/ML.
9. How the Ground Truth for the Training Set Was Established:
As with point 8, the concept of a "training set" and its associated ground truth establishment isn't directly applicable in the same way for this type of device as it would be for an AI/ML diagnostic. The ground truth for the development and calibration of the technology would have been established through rigorous laboratory testing using reference methods and known concentrations of glucose and ketone.
