## L. Test Principle:

The Healthpro™ blood glucose test is based on the measurement of glucose concentration in human blood. This enzyme assay, with a redox chemical “mediator” reaction, is used to generate an electrical current proportional to the glucose concentration in the blood sample. The system is designed as an amperometric measurement device using current generated from the redox reaction as the measurable response.

## M. Performance Characteristics (if/when applicable):

### 1. Analytical performance:

#### a. Precision/Reproducibility:

Within run precision was performed using five venous blood samples spiked with glucose to achieve higher glucose concentration or allowed to age and undergo glycolysis to achieve lower blood concentration. The samples tested ranged from 43 to 332 mg/dL. Each sample was tested 10 times on three test strip lots, using 10 meters per test strip lots for a n = 100 per test strip lot. The mean values and coefficients of variation were calculated for each sample and are summarized below.

b. Linearity/assay reportable range:

A linearity study was performed using fourteen different levels of venous whole blood samples supplemented with a glucose stock solution to cover the claimed measuring range from 20.0 to 600.0 mg/dL. Five measurements were taken from each glucose level and measured using the Healthpro system. First order regression analysis resulted in the equation y = 0.9925x + 1.4254 with an R² = 0.9996. The claimed measuring range is 20 to 600 mg/dL based on the linearity data.

c. Traceability, Stability, Expected values (controls, calibrators, or methods):

Traceability

The glucose control standards are traceable to a NIST glucose standard and are prepared at three concentrations (Level 1 = 50 mg/dL, Level 2 = 110 mg/dL and Level 3 = 300 mg/dL). The reference instrument used is the YSI 2300 Glucose analyzer and is calibrated by YSI 2747 Glucose Standard which is a NIST traceable glucose standard.

Stability

Accelerated stability study was conducted to assess the shelf-life and open-vial stability of the control solutions and test strips. Real-time stability studies are still ongoing. Stability studies protocol and acceptance criteria were provided and found to be adequate.

Unopened control solutions have a 24 month shelf life and are stable for 3 months after first use when stored at 2 - 30 °C (35.6 - 86 °F).

Unopened test strips have a 24 month shelf-life and are stable for 3 months after first use when stored at 2 - 30 °C (35.6 - 86 °F).

Expected values

The controls are prepared at three target concentrations gravimetrically and the glucose concentrations are verified with the YSI reference method. The expected values are verified for each new lot of strips.

d. Detection limit:

See linearity study above in section 1.b.

e. Analytical specificity:

Interference study was designed according to CLSI EP7-A2 guideline. 26 common endogenous and exogenous interfering substances were evaluated by spiking venous blood to three levels of glucose concentrations (60, 150 and 300 mg/dL). The glucose samples were then spiked with the potentially interfering compounds (6 concentration including normal or therapeutic levels and high of toxic levels). Five meters were used for this study. Each sample is tested in replicates of five and a total of 1950 test

strips were used. Bias was calculated as the mean percent difference in glucose reading between the test and control concentration groups. The sponsor claims no significant interference if bias between the tested and the control sample is $< 10\%$ difference. A summary of the concentrations of the potential interfering substances tested is summarized in the table below:

# 2. Comparison studies:

# a. Method comparison with predicate device:

The accuracy of the Healthpro™ Blood Glucose Monitoring System was assessed by comparing blood glucose results obtained from patients with those obtained using the YSI 2300, a laboratory instrument. A total of 160 samples were tested using 6 meters and a total of 960 Healthpro™ test strips.

Only unaltered capillary blood samples are used for glucose concentrations of 50 mg/dL to $400\mathrm{mg / dL}$ . If necessary to obtain sufficient samples in the lowest and highest concentration intervals, glucose concentrations may be adjusted. For preparing some samples in very low glucose ( $< 50\mathrm{mg / dL}$ ) or very high glucose range ( $>400\mathrm{mg / dL}$ ), blood was collected in capillary heparin tubes and then either incubated to allow glucose to hydrolyse or supplemented with glucose. Capillary whole blood glucose was then measured by the Healthpro™ Blood Glucose Monitoring System. The capillary whole blood was then centrifuged, and the plasma glucose was measured by the YSI 2300 Auto analyzer. The data is summarized below:

O. System Descriptions:

1. Modes of Operation:

Each test strip is single use and must be replaced with a new strip for additional readings.

2. Software:

FDA has reviewed applicant’s Hazard Analysis and software development processes for this line of product types:

Yes ☐ X ☐ or No ☐

3. Specimen Identification:

There is no sample identification function with this device. Samples are applied directly to the test strip as they are collected.

4. Specimen Sampling and Handling:

This device is intended to be used with capillary whole blood from the fingertip, which is directly applied to the test strip.

5. Calibration:

The device must be coded with the code found on the current test strip label. No further calibration is required.

6. Quality Control:

There are three levels of glucose control solution (Level 1, 2 and 3) of which Level 2 is included with the test kit and can be run with this device. Recommendations on when to test the control materials are provided in the labeling. An acceptable range for each control level is printed on the test strip vial label. The user is cautioned not to use the meter if the control result falls outside these ranges.

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

1. Hematocrit Study: The effect of different hematocrit levels on the performance of the Healthpro™ Blood Glucose Monitoring System was evaluated using venous whole blood samples with hematocrit levels of 20, 30, 40, 50 and 60% spiked with glucose to achieve 8 concentrations ranging from 32 to 530 mg/dL (32, 73, 121, 185, 253, 371, 459 and 530 mg/dL). Each sample was then tested 15 times and the values were compared with those obtained from YSI 2300. The % biases relative to YSI were acceptable within the claimed hematocrit range of 20 to 60%.

{16}

2. Altitude study: Venous whole blood samples collected from donors were spiked with glucose to whole blood target levels of approximately 66, 220 and 349 mg/dL. Blood glucose target concentrations were then verified by the reference YSI glucose analyzer. Glucose measurements were obtained using the Healthpro™ Blood Glucose Monitoring System in an altitude chamber with adjusted pO2 from 156 to 71 mmHg by tonometry method blowing humidified mixed gas (O2, CO2 and N2) into the blood sample to adjust the pO2 level of the blood. The results demonstrate acceptable bias to YSI to support the claims in the labeling that altitudes up to 10,000 feet have no significant effect on blood glucose measurements from the Healthpro™ Blood Glucose Monitoring System.

3. Sample volume study: The sponsor performed a study to verify the test strip sample volume requirement and the test strip fill error requirement established for the Healthpro™ Blood Glucose Monitoring System. Blood samples were tested at six sample volumes (0.3, 0.5, 0.8, 1.0 and 1.5 μL) and values obtained were compared to YSI values. Results support the claimed sample volume of 0.5 μL and the error code for insufficient sample volume.

4. Temperature and humidity studies: The sponsor performed temperature and humidity studies using venous blood samples to evaluate temperatures ranging from 10°C to 40°C and relative humidity from 10% to 90%. Meter results were compared to YSI 2300 reference analyzer. Four temperature and humidity combinations were tested including low temperature/low humidity, low temperature/high humidity, high temperature/low humidity and high temperature/high humidity. No significant effect (relative to YSI 2300 reference analyzer) was observed with the temperature and humidity combinations tested. The results support the claims in the labeling that the system can be used in conditions of 10 to 40°C with relative humidity of 10 to 90%.

5. Infection Control Studies: The device is intended for single-patient use. Disinfection efficacy studies were performed using materials that comprise the meter and lancing device by an outside commercial testing laboratory demonstrating complete inactivation of hepatitis B (HBV) with CaviWipes Disinfecting Towelettes with EPA registration #46781-8. The sponsor also demonstrated that there was no change in performance or in the external materials of the meter and lancing device after 1,095 cleaning and disinfection cycles (one cycle includes one cleaning wipe plus one disinfecting wipe) to simulate 3 years of meter and lancing device use. Labeling was reviewed for adequate instructions for the validated cleaning and disinfection procedures.

6. The data transmission capability, data transmission port and Healthpro™ Software (firmware and communication) was evaluated in usability study and found to be acceptable. Additionally verification and validation of these functions were conducted and found to be acceptable.

7. EMC testing was evaluated and certified by UL Verification Service and Verification of Compliance certificates provided.

8. Flesch-Kincaid readability assessment was conducted and the results demonstrated that the User Manual, test strip package insert and control solution package insert were written at the 7.8, 7.9 and 7.6 grade levels respectively.
