The system is intended to be used by a single person and should not be shared. It is not intended for use on neonates and is not for the diagnosis or screening of diabetes. The NoCoding1 Blood Glucose Test Strips are for use with the NoCoding1 Plus Blood Glucose Meters to quantitatively measure glucose in fresh capillary whole blood samples drawn from the fingertip. The NoCoding1 Glucose Control Solutions are for use with the NoCoding1 Plus Blood Glucose Meters and NoCoding1 Blood Glucose Test Strips to check that the meter and the test strips are working together properly and that the test is performing correctly.

Device Story

System uses electrochemical biosensor technology to measure glucose in fresh capillary whole blood samples (0.5 µL) from fingertip. User applies blood to test strip inserted into meter; meter measures electrical current generated by glucose oxidase enzyme reaction. Output is quantitative blood glucose concentration (mg/dL) displayed on screen. Used at home by patients with diabetes for self-monitoring. Includes meter, test strips, lancing device, and control solutions for verification. No coding required. Results stored in memory (up to 1,000 tests) with averaging capabilities. Benefits include easy-to-follow instructions for lay users and reliable monitoring of glycemic control.

Clinical Evidence

Clinical study conducted with 371 lay users at three sites. Users performed fingertip capillary blood testing. Results compared against YSI laboratory reference method. For glucose < 75 mg/dL, 97.6% of results were within ± 10 mg/dL. For glucose > 75 mg/dL, 96.1% of results were within ± 10%. Linear regression showed R² = 0.9934. Bench testing included precision (CVs 2.0-5.2%), linearity (13-614 mg/dL), interference testing, hematocrit (15-65%), altitude (up to 10,000 ft), and temperature/humidity robustness.

Blood glucose is measured by the same user, same meters and same strip lots in one day. The repeatability is evaluated for a total of 5 concentration intervals using 10 meters per lot and 3 lots of test strips. The pooled SD of concentration intervals 1 and 2 were 1.9 and 2.1 mg/dL, respectively that were below 5.0 mg/dL. The pooled CV % of concentration intervals 3, 4 and 5 were 2.8, 2.6 and 3.2 %, respectively that were below 5.0 %. All three lots met the acceptance criteria of the repeatability test in all concentration intervals. #### Intermediate Precision Intermediate precision was performed using control solution with 10 operators. Three lots of test strips were evaluated. Glucose testing was conducted by every operator using 3 levels of control solutions for a minimum of 10 days. The pooled SD of concentration interval 1 was 1.4 mg/dL and the pooled CV of concentration intervals 2 and 3 were 3.0 %, 2.4 % respectively. NoCoding 1 Plus have met the acceptance criteria of intermediate precision requirements. #### Linearity Test The linearity of NoCoding1 Plus BGMS was evaluated using whole blood spiked with glucose. Linearity is evaluated for a total of 9 concentration intervals using 5 meters per lot and 3 lots of test strips. Each meter is tested once with each concentration. Three lots of test strips were tested to confirm linearity of NoCoding1 Plus BGMS throughout its measuring range of 20 to 600 mg/dL. All data points are within ±10 mg/dL for glucose concentrations <100 mg/dL and within 10% for glucose concentrations ≥100 mg/dL. Precision was maintained under 5 mg/dL for glucose concentrations <100 mg/dL (SD values) and 5 % for concentrations ≥100 mg/dL (CV values). The linear correlation coefficients (r2) for all strip lots were well above the acceptance criteria of 0.98. within the measured range of 13.1 to 614 mg/dL, over the specification of the measuring range, the performance of test strips has been confirmed to be linear. #### Hematocrit Effect Test Seven different hematocrit levels were tested to evaluate the effect of hematocrit level on measurement of glucose concentration. Each of three different glucose intervals is prepared in seven different hematocrit levels. Three concentration levels of blood samples at seven hematocrit levels were tested for three lots of test strips. For all of the 21 samples, the biases of individual BGMS measurements from YSI were less than 10 mg/dL and 10% below 80 mg/dL and above 100 mg/dL respectively. Hence it has been confirmed that NoCoding1 Plus BGMS has no significant interference within 15 % to 65 % hematocrit levels. {9}------------------------------------------------ Image /page/9/Picture/0 description: The image shows the i-sens logo. The logo is blue, except for two green dots. The first green dot is above the "i" and the second green dot is in the middle of the "i". 43. Banpo-daero 28-gil, Seocho-gu 06646 Seoul, Korea Tel: +82-2-916-6191 Fax #### Interference Test Interference test results have shown that the 24 interferents studied (acetaminophen, ascorbic acid, bilirubin, cholesterol, creatinine, dopamine, EDTA, galactose, gentisic acid, glutathione (Red), hemoglobin, heparin, ibuprofen, icodextrin, L-dopa, maltose, methyldopa, pralidoxime iodide, salicylate, tolbutamide, triglycerides, uric acid and xylose) at significantly high levels have no effect on glucose measurement by NoCoding1 Plus BGMS. The results obtained from the primary tests were sufficient to show non-significance of the presence of these interferents at both low and high glucose concentration intervals. Thus it can be concluded that NoCoding1 Plus BGMS is safe to use for blood glucose monitoring even in the presence of the 24 substances studied. #### Altitude Test Altitude testing is performed inside an altitude chamber where various altitudes are simulated by manipulating the atmospheric pressure inside the chamber. Individual results from NoCoding1 Plus BGMS did not show significant difference (± 10 %) with respect to the reference equipment, nor with different altitudes at all glucose concentrations. Hence it was confirmed that our BGMS has no systematic response to altitudes and is not significantly affected by lack of atmospheric oxygen up to 10,000 feet (3,048m) above the sea level. #### Operating Condition Test The operating conditions of NoCoding1 Plus BGMS are within 6C to 44C and 10 % to 90 % (RH). The test is conducted at 9 different combined temperature and humidity conditions. By evaluating measurement difference from the condition 5 (23℃, 40%) & individual meter value compared to YSI, the performance of NoCoding1 Plus BGMS is demonstrated to be uniformly accurate throughout the actual conditions of use. Operating condition test was conducted at 9 combined temperature-humidity conditions of 6 °℃ and 44 °C at 10%, 40% and 90% RH. We have confirmed that NoCoding1 Plus BGMS operates normally at the presented conditions, individual meter measurements giving less than 10 mg/dL or 10 % bias from YSI reference results. #### Sample volume Test Minimum sample volume for accurate glucose measurement was determined by testing with whole blood samples. Sample volume test was performed using whole blood samples from 3 subjects, each divided into hypoglycemic, euglycemic and hyperglycemic concentrations. When 0.4 uL of sample was applied to the strip, Er 4 messages appeared. The smallest volume required for accurate measurement of NoCoding1 Plus BGMS was 0.5 uL, and the meter bias from YSI were all within the acceptance criteria. {10}------------------------------------------------ Image /page/10/Picture/0 description: The image shows the logo for i-sens.

The study is monitored at three clinical sites against a total of 371 test participants. Approximately ten percent of (10%) but no more than fifteen percent (15%) of naïve subjects have participated in the study. The measurement results have demonstrated that 100 % of data have met the Primary and Reference criteria. Test subjects varied in gender, age and highest level of education, and regardless of the backgrounds, more than 100% of subjects had given scores above 3 (neither easy nor difficult) on the questionnaire. While few of the test subjects were prediabetic and were never exposed to using BGMS on their own, the test results confirm that the instruction given in the User's Guide of NoCoding1 Plus BGMS is easy to follow and that it is easy to use for blood glucose testing. | Site | n | Within<br>± 5 mg/dL | Within<br>± 10 mg/dL | Within<br>± 15 mg/dL | |----------|----|---------------------|----------------------|----------------------| | Combined | 41 | 61.0%<br>(25/41) | 97.6%<br>(40/41) | 100%<br>(41/41) | #### Accuracy results for glucose concentration < 75 mg/dL #### Accuracy results for glucose concentration ≥ 75 mg/dL | Site | n | Within<br>±5% | Within<br>± 10 % | Within<br>± 15 % | Within<br>±20% | |----------|-----|--------------------|--------------------|-------------------|-------------------| | Combined | 330 | 70.0%<br>(231/330) | 96.1%<br>(317/330) | 100%<br>(330/330) | 100%<br>(330/330) | #### Linear regression analysis | Site | Slope | Intercept | R2 | N | Glucose<br>Concentration range<br>(new meter) (mg/dL) | |----------|--------|-----------|--------|-----|-------------------------------------------------------| | Combined | 1.0223 | -1.3686 | 0.9934 | 371 | 48~553 | {11}------------------------------------------------ Image /page/11/Picture/0 description: The image shows the logo for i-sens.
