2. Sample Sizes Used for the Test Set(s) and Data Provenance

  • Repeatability Test: 10 meters, 10 replicates per meter. Total n=100.
    • Data Provenance: Not explicitly stated, but likely in-house lab testing (prospective).
  • Intermediate Precision Test: 10 meters tested over 10 days, one measurement per meter per lot per control solution per day.
    • Data Provenance: Not explicitly stated, but likely in-house lab testing (prospective).
  • System Accuracy Evaluation (ISO 15197): 100 fresh capillary blood samples tested using 2 test strip lots on 2 CONTOUR LINK meters. Total of 400 readings.
    • Data Provenance: Fresh capillary blood samples (prospective). Country of origin not specified, but typically conducted in the submitting company's R&D facilities or contracted labs.
  • Linearity/Assay Reportable Range (Predicate K062058 data cited):
    • Study 1: Blood with 40% hematocrit, 5 glucose concentrations, 3 CONTOUR lots, 24 sensors per lot.
    • Study 2: 8 meters, 3 sensors per lot tested on each.
    • Data Provenance: Unspecified, but derived from the predicate device's 510(k) submission (K062058), so likely both in-house lab testing (prospective) and potentially some clinical data.
  • Detection Limit: 3 production lots of CONTOUR sensors, 24 sensors per sample for manipulated blood samples.
    • Data Provenance: Not explicitly stated, likely in-house lab testing (prospective).
  • Analytical Specificity (Interferences): Not explicitly stated how many samples or replicates were performed for each compound.
    • Data Provenance: Not explicitly stated, likely in-house lab testing (prospective).
  • Method Comparison with Predicate Device (Linearity/Assay Reportable Range comparison): 444 paired readings collected.
    • Data Provenance: Fresh venous blood; likely prospective in-house lab testing.
  • Method Comparison with Predicate Device (CONTOUR LINK vs. CONTOUR meters): 111 subjects (fingerstick study). Two lots of CONTOUR sensors, four CONTOUR meters. RF function of CONTOUR LINK left on.
    • Data Provenance: Fresh capillary blood samples from 111 subjects. Likely prospective clinical or usability study. Country unspecified.
  • Clinical Study (Usability and Accuracy - New Device): 77 adults.
    • Data Provenance: Adults aged 20-85 (fresh capillary blood, self-test and HCP-test results). Likely prospective clinical or usability study. Country unspecified.
  • Clinical Study (Usability and Accuracy - Predicate K062058 cited): 109 adults.
    • Data Provenance: Adults aged 20-75 (self-testing). Derived from predicate device's 510(k) submission (K062058). Likely prospective clinical or usability study. Country unspecified.

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

  • No human experts were used for establishing ground truth. The ground truth in these studies was established using a high-precision laboratory reference method.

4. Adjudication Method for the Test Set

  • Not applicable. Since the ground truth was established by a laboratory reference instrument (YSI 2300 STAT PLUS glucose analyzer) rather than human experts, there was no need for an adjudication method.

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

  • No, an MRMC comparative effectiveness study was not done in the context of comparing human readers (interpreting images/cases) with and without AI assistance. This device is a blood glucose meter, and its performance is assessed against a laboratory reference standard, not against human interpretation of images.
  • A comparative performance study was done between the new device (CONTOUR LINK) and the predicate device (CONTOUR) using blood samples, showing equivalence.

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

  • Yes, the device's accuracy tests (Precision, System Accuracy, Linearity, Detection Limit, Analytical Specificity) represent standalone performance, as these evaluate the device's ability to measure glucose values compared to a reference method, without human intervention in the measurement process itself beyond standard operation. The clinical study also included "HCP-test results" which implies professional use, which would also be standalone.
  • The clinical usability studies involved human users (self-testers and HCPs) operating the device, but the accuracy assessment within these studies is still primarily evaluating the device's standalone measurement capability under real-world usage conditions.

7. The Type of Ground Truth Used

  • Laboratory Reference Method: The primary and most frequently cited ground truth was the YSI 2300 STAT PLUS glucose analyzer.
  • Traceability: The YSI analyzer is traceable to the hexokinase method, which was developed collaboratively by the FDA, CDC, NIST, and AACC. This method utilizes NIST Standard Reference Material 917, dry D-glucose.

8. The Sample Size for the Training Set

  • The document does not explicitly state the sample size for a training set. Blood glucose meters typically do not involve "training sets" in the same way AI algorithms do unless specific machine learning components are involved (which is not described here). The development and calibration of such devices usually rely on extensive internal R&D test data and validated chemical/electrical principles, rather than a publicly reported "training set."

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

  • As the document does not explicitly mention a training set in the context of an AI/ML model, it also does not describe how ground truth for such a set was established. Device calibration and internal validation would rely on the same laboratory reference methods described for the performance studies (e.g., YSI 2300 STAT PLUS traceable to hexokinase method).

for use for self-testing, and the resulting accuracy of results, were assessed.

Results:

Statistical analysis of the data indicates that the probability exceeds 95% that a randomly selected person will successfully perform any of the tasks required for successful execution of the blood glucose testing procedure.

The accuracy study component of the protocol demonstrated that 95,5% of self-test results and 99.4% of HCP-test results satisfy ISO 15197 accuracy specifications (at least 95% of results must be within ±15 mg/dL at <75 mg/dL and ±20% at >75 mg/dL). All control solution test performed by subjects (77) generated inrange glucose values, and all were marked as controls by the meters.

Reference: Predicate 510(k) K062058

Protocol: The subject device is equivalent to the predicate CONTOUR® device with RF transmission capability added. The subject pool included 109 adults aged 20 through 75, each diagnosed with diabetes. The ability to follow instructions for use for self-testing, and the resulting accuracy of results, were assessed.

Results:

Ninety-nine percent of the subjects either did not require any assistance or required answers to questions in an interaction that was comparable to a Customer Service call.

Analytical accuracy of the subjects' self-testing was statistically indistinguishable from the laboratory glucose method. More than 96% were within the limits of ±15 mg/dL or ±20% of the laboratory glucose method, thus meeting the established performance criteria.

CONCLUSIONS/DRAWN FROM NON-CLINICAL AND CLINICAL DATA

The performance of the CONTOUR® LINK Blood Glucose Monitoring System is equivalent to the performance of the previously cleared CONTOUR® Blood Glucose Monitoring System (K062058).

Dear Mr. Ryan:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
