Based on the results of this study, the measuring range was determined to be 20-600 mg/dL.
c. Traceability, Stability, Expected values (controls, calibrators, or methods):
Traceability: The method comparison study was performed using the candidate device and the YSI as the reference method (see section M.2.a.). The MD100 and MD100 Pro are autocoding meters.
Control Value Assignment: The three levels of glucose control solutions are analyzed on the YSI 2300 which has been calibrated with NIST traceable materials. Value assignment is based on testing the control materials on multiple meters and test strip lots. The protocols were reviewed and found to be adequate.
Stability:
MD100 Test Strips: Real time and accelerated stability studies were performed for MD100 test strips to assess the shelf-life and open-vial stability. Stability studies protocol and acceptance criteria for open and unopened vials were provided and found to be adequate to support the labeling claims of 3 months for open vial stability when stored tightly closed between 39°F and 86°F (4°C and 30°C) and 18 month shelf life for unopened vials when stored between 39°F and 86°F (4°C and 30°C).
MD100 Control Solutions: Real time stability studies were performed on open and closed vials at three control levels. Stability studies protocol and acceptance criteria for open and unopened vials were provided and found to be adequate to support the labeling claims of 3 months for open vial stability when stored tightly closed between 39°F and 86°F (4°C and 30°C) and 18 month shelf life for unopened vials when stored between 39°F and 86°F (4°C and 30°C).
d. Detection limit:
See linearity study above.
e. Analytical specificity:
Specificity studies were performed using venous whole blood samples with glucose concentrations of 70-90 mg/dL and 200-285 mg/dL. The low and high glucose
{7}
samples were spiked with potential endogenous and exogenous interferents at therapeutic or reference intervals, and at toxic levels or ten times the therapeutic concentrations. One set of samples was unaltered and used as a control. Samples were analyzed in quintuplicate. Significant interference was defined by the sponsor as $> + / - 10\%$ bias relative to the control.

P. Other Supportive Instrument Performance Characteristics Data Not Covered In The "Performance Characteristics" Section above:
1. EMC testing was evaluated and certified by Aerospace Industrial Development Corporation and a certificate of compliance was issued to Tyson Bioresearch, Inc on Aug. 20, 2010.
2. Drop tests and vibration tests were conducted and results analyzed pre and post testing with the firm's electronic check strip. The sponsor provided the test report to confirm that vibration tests were conducted on 20 meters at maximum vibration intensity (60 Hz) for 45 minutes. The drop test was conducted at approximately 24 and 35 inches and 30 meters were dropped in 6 different orientations. Results of the MD100 Blood Glucose Meter showed that the changes with the electronic check strip before and after challenge were reviewed and deemed acceptable.
3. Sample volume testing was performed with venous whole blood spiked with glucose to yield concentrations of 43.7, 71.4, 146, 254, 374, and 468 mg/dL as determined by the YSI 2300. 10 measurements were obtained from 10 meters and 3 test strip lots using 0.4, 0.5, 0.6 and 0.7 micL of sample for each glucose concentration. The mean was calculated for each glucose concentration. The data supports the sponsor's recommended sample volume of 0.5 mL.
4. Altitude studies were performed using 5 venous whole blood and adjusting the glucose concentration by spiking or glycosylation. Glucose concentrations ranged from 44-360 mg/dL. Samples were tested 10 times on 5 glucose meters and the YSI at 164 ft, 7545 ft, and 9875 ft. The percent bias was calculated against the YSI and the results were found to support the sponsor claims that the MD100/MD100 Pro meter can be used at altitudes up to 7545 ft.

5. Operating Stability: The MD100 glucose meter and test strips were stored together at various combined temperature and humidity conditions to simulate real time operating conditions. Temperature conditions ranged from 10°C - 40°C (50°F-104°F) and 10%-90% relative humidity (RH). Three whole blood samples with glucose concentrations ranging from 70-300 mg/dL were tested with the stored meters and strips. Results were compared to the YSI and met the pre-determined acceptance criteria of ± 10 mg/dL for samples < 75 mg/dL and less than 10% bias for samples ≥ 75 mg/dL. The data supports the claimed operating temperature and humidity ranges of 10°C - 40°C (50°F-104°F) and 10%-90%, respectively.
6. A study was conducted to evaluate the potential interference from hematocrit. Seven different hematocrit levels ranging from 10-70% (10%, 20%, 30%, 42%, 50%, 60%, 70%) were evaluated and at 4 glucose concentrations (~50 mg/dL, ~100 mg/dL, ~288 mg/dL and ~500 mg/dL). Each sample was tested on 5 meters in singlicate. The differences of the glucose meter results at each hematocrit/glucose combination were calculated against YSI-2300 Glucose Analyzer results at 42% hematocrit.
7. Usability Study: For the user performance study summarized in section M.3.c above, the participants were asked to complete a questionnaire to evaluate the ease of use of the device and the clarity of the English language labeling. Overall the users indicated that they could successfully perform the test and that the user manual was written clearly.
8. A separate usability study was performed for downloading glucose meter results to a personal computer. The study participants were males and females of various ages and educational backgrounds. Users found the software easy to use.
