# L. Test Principle:

The iHealth BG5 and BG5L Wireless Smart Gluco-Monitoring Systems are based on an electrochemical biosensor technology (electrochemical) and the principle of capillary action. Capillary action at the end of the test strip draws the blood into the action chamber and the blood glucose result is displayed in 5 seconds.

# a. Precision/Reproducibility:

Within run (repeatability) and total (intermediate) precision was evaluated based on the ISO 15197 guideline.

The repeatability study was performed using heparinized anti-coagulated venous whole blood (hematocrit ranged from $35\%$ to $50\%$ ) spiked to five different glucose concentrations (30-50, 51-110, 111-150, 151-250, 251-400 mg/dL). Each sample was tested on ten meters using three lots of test strips. For each concentration, ten measurements were obtained per meter and test strip lot. (N=100 (10 meters x 10 measurements) per concentration level). Repeatability studies were performed on both BG5 and BG5L meters. The results are summarized below:

b. Linearity/assay reportable range:

Linearity study was designed based on CLSI EP6-A guideline.

Ten heparinized venous blood samples were spiked with dextrose covering the range from 20-600 mg/dL (hematocrit 45%), including 22, 32, 72, 124, 195, 284, 362, 459, 554, and 592 mg/dL. Glucose concentrations were confirmed by the YSI-2300. The study was performed using one calibrated meter and one vial of test on 5 replicates (N=36 per test strip lot). The only difference between the iHealth BG5 and BGL5 Wireless Smart meters is the version of wireless technology (BG5 uses 3.0 and BGL5

{8}

uses 4.0). Therefore, the linearity study was conducted on the iHealth BG5 wireless Smart Gluco-Monitoring System. The results are summarized below:

P. Other Supportive Instrument Performance Characteristics Data Not Covered In The “Performance Characteristics” Section above:

1. Human factor (user performance) study. A human factors study was conducted with 30 enrolled participants. Participants received a dedicated meter and an iOS device and lancing device were recruited in the study.

a. Usability: One purpose of the human factor study was to verify that participants with average education and computer skills and no prior knowledge of the system can safely and accurately use the new device and the data transmission without direct instruction or training. Study results demonstrated that participants were able to transmit results from the meter to the iOS device via Bluetooth technology.

b. Readability: The participants were also asked to complete a questionnaire to evaluate the ease of use of the device and the clarity of the English language labeling. The readability of the labeling (user guides and test strip package insert) using a Flesch-Kincaid analysis were found to be written at the 8th grade level. Overall the users indicated that they could successfully perform the test and that the user manual was

11

{11}

written clearly.

2. IOS device data storage and memory roll over study: To assess the storage of the IOS device and the memory data rollover function, 10,000 data records were input into IOS device. The integrity of the stored data was confirmed by the data in BG5 glucose meters with 100% accuracy. The study demonstrated that the new data will replace the existed data orderly after the memory area room is full.

3. Electromagnetic Compatibility (EMC) testing was performed/ passed and a certificate was provided.

4. Hematocrit study. Evaluated in k120813.

5. Altitude Study. Evaluated in k120813.

6. Temperature and Relative Humidity Study. Evaluated in k120813.

7. Sample Volume Study. Evaluated in k120813.

8. Infection control: Candidate devices consist of same materials as the devices cleared under k110017. See k110017 for disinfection efficacy study information. Robustness studies were performed by the sponsor for this current submission demonstrating that there was no change in performance or external materials for each of the meters and lancing device after 11,000 cycles (each cycle contained pre-cleaning and disinfection steps) with the CaviWipes. The robustness studies were designed to simulate 5 years of single-patient use. Labeling was reviewed for adequate instructions for the validated cleaning and disinfection procedures.
