2. Sample Sizes and Data Provenance

  • User Performance Clinical Evaluation:
    • Test Set Sample Size: 360 typical users.
    • Data Provenance: The document does not specify the country of origin, but the submitting company is HMD BioMedical Inc. based in Taiwan. The study is described as a "User performance evaluation" and "clinical evaluation," implying prospective data collection with human participants.
  • System Accuracy Evaluation at Extreme Glucose Values:
    • Test Set Sample Size: 100 subjects.
    • Data Provenance: The document does not specify the country of origin. This also appears to be prospectively collected clinical data from human subjects.
  • Within-run precision evaluation: 100 samples (for Lot 1, and presumably for Lots 2 and 3 as well, making it 300 samples total across lots). Data provenance is not specified beyond being laboratory-generated.
  • Intermediate precision (day-to-day) evaluation: Number of samples not explicitly stated per lot, but given the structure, it likely involves multiple measurements over several days across different glucose levels and lots. Data provenance is not specified beyond being laboratory-generated.
  • Other studies (Altitude, Hematocrit, Interference, etc.): Sample sizes are generally not explicitly quantified beyond statements like "five glucose measures at each attitude level" or "3 different levels of glucose concentrations" with "26 endogenous and exogenous substances." These are typically laboratory-based tests.

3. Number of Experts and Qualifications for Ground Truth

  • No information provided: The document does not mention the number of experts or their qualifications used to establish ground truth for any of the studies.
  • Implied Standard Reference Method: The ground truth for glucose measurements (e.g., in user performance and system accuracy studies) is consistently compared against a "YSI 2300." The YSI 2300 STAT Plus Glucose & Lactate Analyzer is a laboratory reference method widely accepted for accurate glucose measurement. This suggests that the ground truth is established by a highly accurate laboratory instrument, not human experts in the traditional sense of image interpretation.

4. Adjudication Method for the Test Set

  • None applicable: For glucose monitoring systems, ground truth is established by a reference laboratory instrument (YSI 2300). There is no "adjudication" between human readers or experts as there would be for image interpretation tasks. The comparison is directly between the device's reading and the YSI's reading.

5. MRMC Comparative Effectiveness Study

  • Not Applicable: This type of study (Multi-Reader Multi-Case comparative effectiveness, assessing human reader improvement with/without AI assistance) is typically relevant for interpretative medical tasks (e.g., radiology AI). The GlucoLeader Enhance is a direct measurement device, not an AI or interpretive tool that assists human readers. Therefore, no such study was conducted or is relevant.

6. Standalone Performance

  • Yes, standalone performance was done: All listed performance studies (User performance, System Accuracy, Precision, Linearity, Hematocrit, Interference, etc.) evaluate the algorithm/device's performance directly against a reference method (YSI 2300) without human intervention in the measurement interpretation itself. The "User performance clinical evaluation" assesses how typical users operate the device and obtain results, but the accuracy assessment is still the device's output versus the reference.

7. Type of Ground Truth Used

  • Reference Laboratory Method / Expert Instrument: The ground truth for glucose concentration measurements is established using the YSI 2300 (likely the YSI 2300 STAT Plus Glucose & Lactate Analyzer), which is a highly accurate and widely accepted laboratory reference instrument for glucose measurement. This falls under the category of a "reference standard" or "expert instrument" rather than direct human expert consensus or pathology data.

8. Sample Size for the Training Set

  • Not applicable / Not explicitly stated: For a traditional medical device like a blood glucose monitor, there isn't typically a "training set" in the machine learning sense. The device's performance is based on its electrochemical methodology and calibration, not on a machine learning model trained on a dataset. The document does not provide details on development or calibration data, which might be analogous to a training set for machine learning devices, but it's not discussed in those terms.

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

  • Not applicable: As explained above, for this type of device, a "training set" in the machine learning context is not relevant. The device is calibrated during manufacturing using reference standards, but detailed procedures for this are not part of the regulatory submission about performance testing.

● Test Principle

Blood glucose is measured by an electrical current that is produced when a blood sample mixes with the reagent (special chemicals) of the test strip. The electrical current changes with the amount of glucose in the blood sample. The meters measure the strength of the electrical current, calculate your blood glucose level and then display your result in either default unit mg/dL or mmol/L. The GlucoLeader Enhance Blood Glucose Meter, GlucoLeader Enhance Blood Glucose Test Strips and GlucoLeader Enhance Glucose Control Solutions have been designed, tested and proven to work together as a system to produce accurate blood glucose concentration test results.

● Substantial Equivalence Discussions

A claim of substantial equivalence is made to GlucoLeader Enhance Self-Monitoring of Blood Glucose System (K032985). Both of them have the similar indications for use, the same working principle, technologies and detection method. The minor differences for the two devices are LCD screen size, meter dimensions, meter weight, reaction time, data memory, meter storage environment, measuring range, enzyme, minimum sample volume, strip accuracy, HCT range, system operating environment, and strip storage environment,

The GlucoLeader Enhance Blood Glucose Test Strips have been updated with Glucose Dehydrogenase-FAD Enzyme, which not only improves the accuracy to the standard, but also increases the HCT interference range up to 10-70%. The test required blood sample volume reduced to 0.8 µL, and the test reaction time is only 5 seconds

Most of these differences have been validated through the respective non-clinical and clinical testing to indicate there are no any new safety and effectiveness concerns raised. Besides, the subject device and predicate device have the similar intended for use in the quantitative measurement of glucose in fresh capillary whole blood drawn from the fingers. Thus the differences are shown to be due to the feature design aspects, not to raise any new safety or effectiveness concerns.

The conclusions drawn from the non-clinical and clinical tests demonstrate that the device is as safe, as effective, and performs as well as the legally marketed device identified in the submission. Thus the subject device is substantially equivalent to the predicate devices.
