## IV Device/System Characteristics:

### A Device Description:

The GlucoSure Link blood glucose monitoring system (model number BGM024) consists of the GlucoSure Link meter, GlucoSure Link Blood Glucose Test Strips and Contrex Plus glucose control solutions (Level 1, Level 2, and Level 3). The GlucoSure Link Blood Glucose Test Strips and Contrex Plus glucose control solution are available for purchase separately.

### B Principle of Operation:

The GlucoSure Link blood glucose monitoring system quantitatively measures glucose amperometrically, using test strips containing an enzyme (Glucose Oxidase). Glucose in the whole blood sample applied to the test strip reacts with the glucose oxidase. The electrons generated during this reaction are detected by the meter. The meter applies a small electrical current to the test strip and measures changes in the current caused by the reaction of glucose in the blood sample to the enzyme in the test strip. The magnitude of the resultant current is proportional to the concentration of glucose in the blood and is converted to a glucose concentration. The glucose concentration is displayed on the meter's display. The test results are plasma-calibrated.

### C Instrument Description Information:

1. Instrument Name:

GlucoSure Link Blood Glucose meter

2. Specimen Identification:

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

VII Performance Characteristics (if/when applicable):

A Analytical Performance:

1. Precision/Reproducibility:

A within-run precision study using 3 lots of GlucoSure Link Blood Glucose test strips was performed. Venous blood was spiked to 5 concentrations (i.e., Level 1: 30-50 mg/dL, Level 2: 51-110 mg/dL, Level 3: 111-150 mg/dL, Level 4: 151-250 mg/dL, and Level 5: 251-400 mg/dL). For each sample concentration, 10 GlucoSure Link Blood Glucose meters were used, with 10 measurements taken by each meter for a total of 300 test for each glucose level. Results are summarized below:

| Control Levels | N | Mean (mg/dL) | SD (mg/dL) | CV (%) |
| --- | --- | --- | --- | --- |
| L1 | 300 | 46 | 2.6 | 5.6 |
| L2 | 300 | 89 | 3.0 | 3.3 |
| L3 | 300 | 120 | 3.5 | 2.9 |
| L4 | 300 | 221 | 5.1 | 2.3 |
| L5 | 300 | 328 | 5.1 | 1.6 |

Intermediate precision was evaluated using 3 lots of the GlucoSure Link Blood Glucose test strips and five levels of control solutions (i.e., Level 1: 30-50 mg/dL, Level 2: 51-110 mg/dL, Level 3: 111-150 mg/dL, Level 4: 151-250 mg/dL, and Level 5: 251-400 mg/dL). Each sample was measured in replicates of 10 using 10 GlucoSure Link Blood Glucose meters over ten days resulting in a total of 300 tests for each glucose level. Results are summarized below:

| Control Levels | N | Mean (mg/dL) | SD (mg/dL) | CV (%) |
| --- | --- | --- | --- | --- |
| L1 | 300 | 40 | 1.6 | 3.9% |
| L2 | 300 | 69 | 2.0 | 2.9% |
| L3 | 300 | 121 | 2.0 | 1.7% |
| L4 | 300 | 222 | 2.2 | 1.0% |
| L5 | 300 | 329 | 2.7 | 0.8% |

2. Linearity:

Linearity was evaluated using venous whole blood adjusted to eleven glucose levels at 19.7, 50.1, 80.7, 115, 160, 200, 260, 310, 420, 530, and 610 mg/dL (as measured by the comparator method, YSI 2300) and 3 GlucoSure Link Blood Glucose test strip lots. The GlucoSure Link Blood Glucose Monitoring System results were compared with the values obtained from the comparator method. The results from the regression analysis are summarized below:

Lot 1: y = 0.9972x-0.1961, R2=0.9985
Lot 2: y = 1.0035x-1.0736, R2=0.9984
Lot 3: y = 1.0027x-0.8429, R2=0.9983

The results of the study support the sponsor's claimed glucose measurement range of 20 to 600 mg/dL. If a sample is less than 20 mg/dL, the result is flagged by the meter as "LO". If a sample result is more than 600 mg/dL, the result is flagged by the meter as "HI". The low and high functions were validated and demonstrated to function as intended.

3. Analytical Specificity/Interference:

Interference testing was conducted to evaluate the effect of endogenous substances and common exogenous substances expected in the intended use population on the GlucoSure Link Blood Glucose Monitoring System. The study was designed using venous whole blood samples adjusted to 3 target glucose levels (50-70 mg/dL, 110-130 mg/dL, and 225-270 mg/dL). Samples were divided into a test pool with the potential interferent added and a control sample with no added interferent. The difference between the test and control sample results was calculated and the concentration at which no significant interference (defined as average % bias ≤ 10%) was observed is listed in the table below:

| Substances | Highest concentration at which no significant interference is observed | Substances | Highest concentration at which no significant interference is observed |

# F Other Supportive Instrument Performance Characteristics Data:

1) System operating conditions (temperature, humidity):

The GlucoSure Link Blood Glucose Monitoring System was tested at different temperature and humidity conditions to assess the effect of the operation environment on the performance of the system. Temperatures ranging from 50 - 104°F (10 - 40°C) and 20 - 85% relative humidity were tested. Five temperature and humidity combinations were tested including low temperature/low humidity, low temperature/high humidity, high temperature/low humidity and high temperature/high humidity. Venous whole blood glucose levels (60, 120, 200, and 400 mg/dL) were tested using 10 meters and 3 lots of GlucoSure Link Blood Glucose test strips. Values measured by the GlucoSure Link Blood Glucose Monitoring System were compared to the results obtained using the comparator method, the YSI 2300 method. The study results support the labeled operating conditions claim of 50-104°F (10-40°C) and 20-85% RH.

2) Sample Volume Study:

The sponsor performed a study to support the claimed minimum sample volume of 1.0 μL for the GlucoSure Link Blood Glucose Monitoring System. Venous whole blood samples with 3 glucose concentrations (50-65, 100-120 and 200-250 mg/dL) were tested at 5 sample volumes (0.8, 0.9, 1.0, 1.1 and 1.2 μL) using 3 lots of GlucoSure Link Blood Glucose test strips and 10 GlucoSure Link meters. Values obtained were compared to the results obtained using the comparator method (YSI 2300 Glucose analyzer). Results support the claimed minimum sample volume of 1.0 μL for the system. The meter displays an error message if enough blood is not added to the test strip. This feature was validated and was shown to function as intended.

3) Hematocrit Study:

The effect of hematocrit on the performance of the GlucoSure Link Blood Glucose Monitoring System was evaluated at 30%, 35%, 42%, 50%, and 55% hematocrit levels, and at 5 glucose concentrations (30-50, 51-110, 111-150, 151-250 and 251-400 mg/dL). Each sample was tested in replicates of 10 using 10 meters and 3 lots of GlucoSure Link Blood Glucose test strips, for a total of 30 replicates per sample. The values were compared with the glucose measurements obtained using the comparator method (YSI 2300 Glucose analyzer). The results of the study demonstrated adequate performance to support the claimed hematocrit range of 30%-55%.

4) Altitude Study:

A high-altitude study was conducted where the effects of sea level (&lt;500 ft) and high-altitude (10,000 ft) were simulated and the effects on the GlucoSure Blood Glucose Monitoring System were evaluated. Venous whole blood samples adjusted to 5 glucose concentrations (50, 120, 220, 330, and 450 mg/dL) were tested using 10 meters and 3 lots of GlucoSure Link Blood Glucose test strips. Values measured by the candidate device were compared with the glucose measurements obtained with the comparator method (YSI 2300 Glucose analyzer). The results of the study support the claim that the

{11}

GlucoSure Blood Glucose Monitoring System can be operated at altitudes of up to 10,000 ft.

5) Flex Studies:

Flex studies were performed demonstrating that the GlucoSure Link Blood Glucose Monitoring System is robust to short sample application, sample perturbation, testing with used test strips, intermittent sampling, drop and vibration.

6) Infection Control Studies:

The device system is intended for single patient use. Disinfection efficacy studies were previously performed (k150396) with the external meter materials by an outside commercial testing laboratory demonstrating complete inactivation of hepatitis B virus (HBV) or removal of HBsAg with the following disinfectants: Clorox Healthcare Bleach Germicidal and Disinfectant Wipes (EPA Registration Number: 67619-12), Dispatch Hospital Cleaner Disinfectant Towels with Bleach (EPA Registration Number: 56392-8), Medline Micro-Kill+ Disinfecting, Deodorizing, Cleaning Wipes with Alcohol (EPA Registration Number: 59894-10), and Medline Micro-Kill Bleach Germicidal Bleach Wipes (EPA Registration Number: 69687-1-37549). The sponsor also conducted robustness studies demonstrating that there was no change in performance or to the external materials of the meter after 260 cleaning and disinfection cycles (representing weekly disinfection for five years, the expected lifetime of the meter). Labeling was reviewed for adequate instructions for the validated cleaning and disinfection procedures.

7) The sponsor provided acceptable documentation certifying that acceptable electrical safety and electromagnetic compatibility (EMC) testing was performed with the candidate system and the system was found to be compliant.

8) Test strip lot release criteria: The test strip lot release protocols and criteria were reviewed and found to be acceptable.

VIII Proposed Labeling:

The labeling does supports the finding of substantial equivalence for this device.

IX Conclusion:

The submitted information in this premarket notification is complete and does support a substantial equivalence decision.
