## L. Test Principle:

The OneTouch Verio IQ Blood Glucose Monitoring System uses flavin adenine dinucleotide-glucose dehydrogenase (GDH-FAD) enzyme chemistry as the standard dry reagent assay for glucose in whole 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 for the redox reaction as the measureable response.

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

### 1. Analytical performance:

a. Precision/Reproducibility:

Within-run precision was measured by using whole blood with sodium heparin as the anti-coagulant at five different glucose concentrations. Each

{4}

sample was tested on 3 lots of test strips on 30 meters (10 meters per test strip lot). Ten replicates were tested per meter, test strip lot, and glucose concentration, $(N = 100$ per test strip). Results are summarized below:

| Glucose Level (mg/dL) | Strip Lot | Mean (mg/dL) | SD (mg/dL) | %CV |
| --- | --- | --- | --- | --- |
| 40 | 1 | 42.3 | 1.21 | 2.85 |

b. Linearity/assay reportable range:

The linearity study was designed following CLSI EP6-A guideline. Nine human venous whole blood samples were drawn and spiked to target analyte levels. Eight target levels were prepared with glucose stock solutions to glucose concentrations ranging from 20 to 600 mg/dL. All samples were tested on 3 lots of test strips in duplicate using one the OneTouch Verio IQ meter. All samples were also tested on the YSI 2300 analyzer to generate the expected values. The observed values were plotted against the expected values and an appropriate line fitted by standard linear regression was generated with results summarized below:

| Strip Lot | Slope | Intercept | R² |
| --- | --- | --- | --- |
| 1 | 0.939 | 3.44 | 0.998 |
| 2 | 0.932 | 3.60 | 0.998 |
| 3 | 0.939 | 3.77 | 0.998 |

The sponsor's claimed range for the glucose assay is linear from 20-600 mg/dL.

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

Traceability: OneTouch Verio IQ Blood Glucose Monitoring System is traceable to the NIST SRM 917b reference material.

Controls and Test Strips previously cleared: See k093745 for traceability, stability, and expected value information. OneTouch Verio Control solutions submitted for k093745 are the same control solution material and same concentrations as the control material used for this current submission k110637. Due to changes in labeling regulations, these control materials have been renamed for this current submission k110637.

OneTouch Verio Control Solutions:

Value assignment:

The value assignment of the OneTouch Verio control solutions were determined by an in-house procedure. The control solutions were prepared by gravimetric addition of glucose to achieve target values of 120 ± 15 mg/dL for level 3 and 350 ± 15 mg/dL for level 4 and values were confirmed by a laboratory method. Verification of the control solutions were tested with 100 test strips and 10 meters with each level and the target ranges were set at the following:

{6}

7

| Glucose control solution | Target concentration | Acceptable range |
| --- | --- | --- |
| Level 3 (medium) | 120 mg/dL | 120 ± 15% (102-138 mg/dL) |
| Level 4 (high) | 350 mg/dL | 350 ± 15% (298-403 mg/dL) |

Stability:

Real time stability was performed to assess the shelf-life and open-vial stability of the control solutions and test strips. Stability studies protocol and acceptance criteria were provided and found to be adequate. Unopened control solutions have a 15 month shelf life and are stable for 3 months after first use when stored at 5-30°C (41-86 °F). Unopened test strips have a 12 month shelf-life and are stable for 3 months after first use when stored at 5-30°C (41-86 °F). This information is provided in the labeling of the test strips and control materials.

d. Detection limit:

See linearity study above.

e. Analytical specificity:

Interference study was designed according to CLSI EP7-A2 guideline. 23 common endogenous and exogenous interference substances were evaluated by spiking venous whole blood with two levels glucose concentrations (65 mg/dL and 240 mg/dL).

The glucose samples were spiked with the potentially interfering compounds and tested on 3 lot of test strips. Each glucose concentration has five different concentrations of the interference substances. The labelling states that elevated concentrations of acetaminophen, ascorbic acid, uric acid, tolazamide, and xylose may affect the blood glucose results. Bias was calculated as the difference between the test and control concentration groups. The sponsor claims no significant interference for the substances and concentrations shown in the table below:

| Endogenous Compounds | High Normal/High Therapeutic Level (mg/dL) | Concentration tested up to (mg/dL) |
| --- | --- | --- |
| Ascorbic Acid | 2.0 | 6.0 |

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

1. Altitude Study:

This study was conducted to evaluate the effect of altitude on the OneTouch Verio IQ BGMS. Three (3) lots of test strips were tested on 16 meters using blood from three donors at three glucose concentrations (70, 240, and 450 mg/dL) at three altitude levels (3000, 6000, and 10,000 feet), and at sea level (0 feet) as a control. In addition, testing was performed in a hyperbaric chamber. Each venous blood sample was tested on the OneTouch Verio IQ Blood Glucose monitor and the meter readings obtained were compared to the YSI method; then analyzed as a bias difference. Based on the data, the OneTouch Verio IQ BGMS can be used at altitudes up to 10,000 feet. The glucose values obtained using the OneTouch Verio IQ had biases that were within +/-10 of glucose values obtained at sea level.

2. Hematocrit Study -

The sponsor performed hematocrit studies using five different hematocrits (Hct) (19, 30, 40, 50 and 61%) levels across the glucose measuring range (20 - 600 mg/dL). At each hematocrit level, each test strip lot was tested with three samples, at each of the five glucose levels (30, 65, 240, 450, and 560 mg/dL). Three lots of test strips were tested on 12 meters and the values were compared to the YSI method. The sponsor claimed that hematocrit values between 20% to 60% do not significantly affect the glucose results. The glucose values obtained using the OneTouch Verio IQ were within +/- 15% of the glucose values obtained using the YSI method.

3. Temperature and Relative Humidity Study:

In this study, three test strip lots were tested at 9 combined temperature and relative humidity conditions, including the nominal conditions (22°C/50% RH) and eight conditions at the limits of the claimed temperature/relative humidity ranges. Temperatures evaluated ranged from 5°C to 45°C and relative humidity from 10% to 90%. Each sample tested was also compared to the YSI reference method. The study was conducted over four days, with each day the nominal T/RH condition (22°C/50% RH) was tested along with two extreme temperature/relative humidity conditions. Three blood samples were adjusted to target glucose concentrations of 65, 240, and 450 mg/dL. At each T/RH condition, two replicates on six meters were obtained for each donor, glucose level and test strip lot (N=108 tests per strip lot). The results supported the Sponsor's claimed operating temperature from 5°C to 45°C (41°F to 113°F) and relative humidity range from 10% to 90%.
