Device Story
The i-QARE DS-W is a portable blood glucose monitoring system for home use by patients with diabetes. It utilizes an electrochemical biosensor with carbon electrodes to measure glucose levels in fresh capillary whole blood. The user applies a 0.7 µL blood sample to a test strip, which uses capillary action to draw the sample into an internal chamber. The meter processes the electrochemical signal and displays the glucose concentration within 6 seconds. The device is operated by a single button and features a code-card-free design to simplify usage and reduce user error. It stores up to 20 test results for patient review. The system provides patients with a convenient, point-of-care method to monitor diabetes control, aiding in the management of their condition. It is not intended for use in critically ill patients or for diagnostic screening.

L. Test Principle:
The i-QARE DS-W Blood Glucose Monitoring System uses electrochemical methodologies. The system quantitatively measures blood glucose levels using an amperometric method. The system employs glucose oxidase enzyme chemistry. The electrons generated during this reaction are transferred from the blood to the electrodes. The magnitude of the resultant current is proportional to the concentration of glucose in the specimen and the signal is converted into a readout displayed on the meter.
M. Performance Characteristics (if/when applicable):
1. Analytical performance:
a. Precision/Reproducibility:
The sponsor performed repeatability (with-in run precision) studies using venous whole blood samples at five glucose concentrations (target values 40, 80, 120, 200, and 300 mg/dL) using 10 meters. Each glucose concentration was analyzed in replicates of 40 for each of three strip lots resulting in a total of 120 measurements per concentration. Results are summarized below:

b. Linearity/assay reportable range:
The sponsor performed linearity studies using adjusted venous blood samples with eight different glucose concentrations (as measured by YSI) of 17, 45, 101, 149, 245, 328, 538, and 603 mg/dL. For each glucose concentration, twenty-one measurements were made per strip lot, for each of 3 test strip lots. The data from the DS-W Blood Glucose Monitoring System was compared to the reference method (YSI). Results from linear regression analyses were as follows:
| Strip Lot | Slope | y-intercept | R² |
| --- | --- | --- | --- |
| Lot #1 | 1.0078 | 0.1256 | 0.9989 |
| Lot #2 | 1.0053 | 1.6559 | 0.9995 |
| Lot #3 | 0.998 | 2.2109 | 0.9993 |
The results of this study support the sponsor's claimed glucose measuring range of 20 - 600 mg/dL. Results less than 20 mg/dL will be displayed as LO, and results greater than 600 mg/dL will be displayed as HI.
c. Traceability, Stability, Expected values (controls, calibrators, or methods):
Traceability:
The i-QARE DS-W Blood Glucose Monitoring System is traceable to the NIST SRM 917b reference material. The method comparison study was performed using the candidate device and YSI as the reference method (see Section 2.a.).

{6}
73.4°F-80.6°F (23°C to 27°C). The opened-vial stability claim for the control solutions is 90 days from first opening when stored at 68°F-86°F (20°C to 30°C).
d. Detection limit:
The measuring range for this device is 20 – 600 mg/dL. Please refer to the linearity study in section M.1.b. above.
e. Analytical specificity:
To assess potential interference the sponsor used venous whole blood samples adjusted to two glucose concentration intervals of 70 to 75 mg/dL and 200 to 250 mg/dL. Each of these samples was divided into a test pool and a control pool and each of the potential endogenous and exogenous interfering substances was added to the test pool. Each substance was tested at a minimum of two concentrations, normal/therapeutic and high/toxic concentrations. The % difference between the test sample and the control sample was calculated. The sponsor defines no significant interference as ≤ ± 10 % difference for each individual replicate relative to the control sample. Results are presented in the table below:

5. Calibration:
Users are instructed to match the code number of the test strip to that displayed by the meter for each box of test strips.
6. Quality Control:
Glucose control solutions (previously cleared, k082965) at two different concentrations (Level 1 and Level 2) can be run with this device and Control Level 1 is provided with the kit. The meter automatically distinguishes control solution from blood and marks control solution tests with a check mark and excludes them from average calculations. 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 bottle 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. Altitude Study:
The effect of altitude on device performance was evaluated with one test strip lot and five meters using contrived venous blood samples from three donors. Samples were spiked to 5 glucose concentrations (50, 120, 200, 350, and 500 mg/dL). The samples were tested at 2543, 5446, 6529, and 8563 feet above sea level and at sea level (0 feet) as a control. Results obtained were compared with those obtained with the reference method (YSI). The results demonstrate acceptable bias to the reference to support the claims in the labeling that altitudes up to 8563 feet have no significant effect on blood glucose measurements from the DS-W Blood Glucose Monitoring System.
2. Hematocrit Study:
The effect of different hematocrit levels was evaluated using venous whole blood
11
{11}
samples with hematocrit levels of 20 – 60% (20, 25, 30, 35, 40, 45, 50, 55 and 60%) spiked with glucose to achieve concentrations of 50, 120, 250, and 500 mg/dL. Results of samples at each hematocrit level were compared to samples with the same glucose concentration at normal (40%) hematocrit as well as to the corresponding YSI value. The % bias of the i-QARE DS-W Blood Glucose meter results relative to YSI demonstrated adequate performance to support the claimed hematocrit range of 20 – 60%.
## 3. Test System operating conditions:
The sponsor evaluated the effect of temperature and relative humidity (RH) on the performance of the DS-W Blood Glucose Monitoring System using venous blood samples at 50, 250, and 500 mg/dL glucose. The following combined temperature and humidity conditions were evaluated and compared with results obtained with the YSI reference method: 14°, 18°, 22°, 25°, 28°, 32°, 36°, and 40°C at relative humidities of 10, 40, 65, and 95%. The study results support the claimed operating temperature range of 57°F to 104°F (14°C to 40°C) with relative humidity of 10 – 95%.
## 4. EMC Testing:
The sponsor provided documentation certifying that acceptable electromagnetic testing (EMC) had been performed.
## 5. Readability Assessment:
The readability of the labeling (Owner’s Booklet, Control Solution Insert, and Test Strip Insert) using a Flesch-Kincaid analysis were found to be written at an 8th grade level or below.
## 6. Software documentation:
The software documentation was reviewed and found to be acceptable. The firm provided documentation to support the device was designed, developed and is under good software lifecycle processes.
## 7. Infection Control Studies:
The device system is intended for single-patient use only. Disinfection efficacy studies were performed on the materials comprising the meter by an outside commercial testing laboratory demonstrating complete inactivation of Hepatitis B Surface Antigen (HBsAg) with the chosen disinfectant, Dispatch Hospital Cleaner Disinfectant with Bleach (EPA Registration # 56392-8). Robustness studies were also performed by the sponsor demonstrating that there was no change in performance or external materials of the meter after 260 cleaning and disinfection cycles with the Dispatch wipes. 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.
## Q. Proposed Labeling:
The labeling is sufficient and it satisfies the requirements of 21 CFR Part 809.10.
