## M. Performance Characteristics (if/when applicable):
Since BeneCheck™ Premium GLU and BeneCheck™ Premium PRO GLU Monitoring Systems are identical, only one set of performance studies were provided for both the systems.
## 1. Analytical performance:
### a. Precision/Reproducibility:
The repeatability study was performed by three operators using venous whole blood (hematocrit ranged from 40 to 45%) at five different glucose concentrations. The final glucose concentration for the blood samples were confirmed by YSI2300. Each sample was tested ten times on ten meters with each of the three lots of test strips. Ten measurements were obtained per meter and test strip lot combination, and glucose concentration (N=300 per concentration level). The results are summarized below:

# BeneCheck Premium GLU Control Solutions:
Traceability and value assignment – The BeneCheck™ Premium GLU and PRO GLU Monitoring System’s glucose assay is traceable to the N.I.S.T SRM 917c and the YSI-2300 STAT PLUS (glucose oxidase) analyzer.
Value assignment for the BeneCheck™ Premium GLU and PRO GLU Control Solutions is performed with ten BeneCheck™ Premium GLU meters using 20 vials of BeneCheck™ Premium GLU test strips from each of the three lots. The mean, standard deviation and CV are calculated for each new lot of control material. If the three CVs, each from three lots of test strips, are ≤5%, then the control range for each strip lot is calculated. If the CV is >5%, the product is judged defective and discarded.
Stability - The sponsor has provided a control solution (levels - 1, 2 and 3) storage stability study protocol and acceptance criteria to support their storage stability claim for the open vial of 90 days and for shelf life of 24 months when stored at 50°F to 86°F (10°C to 30°C). The accelerated testing at 122°F (50°C) for 95 days of closed vial supports the shelf life of 24 months, and the real time testing is on-going. The real time testing of open vial supports the storage claim of 90 days.
# BeneCheck™ Premium GLU Test Strips:
Stability - The sponsor has provided a test strip storage stability study protocol and acceptance criteria to support their storage stability claim for the open vial of 90 days and for shelf life of 24 months when stored at 50°F to 86°F (10°C to 30°C) and 10% to 90% RH. The accelerated testing at 122°F (50°C) for 90 days of closed vial supports the shelf life of 24 months, and the real time testing is on-going (180 days of testing completed). The real time testing of open vial supports the storage claim of 90 days.
This information is provided in the labeling of the test strips and control materials.
## d. Detection limit:
The reportable range is 20 to 600 mg/dL based on the linearity/assay reportable range study (section M.1.b).
## e. Analytical specificity:
Interference study was designed according to CLSI EP7-A2 guideline.
Twenty six potential endogenous and exogenous interfering substances were evaluated by spiking venous blood (HCT 42.5%) to two levels of glucose concentrations within the ranges 60 - 100 mg/dL and 200 - 300 mg/dL. The glucose samples were spiked with the potentially interfering compounds and tested on five meters using one test strip lot. Several concentrations of the interfering substances were tested. Bias was calculated as individual percent difference in glucose reading between the test and control concentration groups. Significant interference is defined by the sponsor as a bias >10% of the test samples from the control group.
The sponsor claims no significant interference (≤10% difference) for the substances

Lay User Performance Study:
Lay user studies for fingerstick, palm and forearm were performed by 151 lay users and healthcare professionals using fresh capillary blood samples at eight locations in US. Labeling was provided only in English and users followed it to perform the testing. The lay user first performed the testing of the finger, palm and forearm followed by the healthcare professional performing the testing. Then within 5 minutes, capillary whole blood samples were collected in heparin tubes, plasma was separated, frozen and sent for testing on YSI. The samples were tested using three lots of Premium test strips which were distributed randomly to the lay users. All results were compared to the YSI. Results are summarized below:

{12}
The glucose test is intended to be used with capillary whole blood from the finger, palm and forearm. The whole blood sample is applied directly to the test strip by capillary action.
5. Calibration:
The BeneCheck Premium Glu meter and the BeneCheck Premium PRO Glu meter are autocoding devices.
6. Quality Control:
The BeneCheck Premium Glu and BeneCheck Premium PRO Glu control solutions at three concentration levels (1, 2, 3) can be run with this device. The meter has to be set in control solution test mode to prevent control results from being stored in the internal memory as patient result. Recommendations on when to test the control materials are provided in the labeling. The control solution readings are not included in the average of the patient results. An acceptable range for each control level is printed on the test strip vial 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. A labeling comprehension study was performed as a part of the lay user clinical study. The recruited 152 lay users (aged 18-83 yrs old) were provided with all labeling in English for the US market and a questionnaire. Participants varied in age, education, country of origin, and both men (n = 90) and women (n = 62) were included in the study. These lay users completed the questionnaire to indicate whether the device is easy to use and the Instructions for use were written in a way that makes it easy to use. The majority of the users responded that the device is very easy to use.
2. Flesch-Kincaid readability assessment was conducted and the results showed that the labeling (User manual, Quick Guide, test strip package insert and control solution package insert) were written at grade levels ranging from 7.0th to 8.0th grade.
3. The effect of different hematocrit levels on the accuracy of the device was evaluated on the Premium Blood Glucose Monitoring System using eight meters (tested in eight replicates) and three lots of test strips. Venous blood samples at six hematocrit levels from 25% to 60% (25, 30, 42.5, 50, 55 and 60%) were evaluated at four concentrations of glucose (47, 97, 222 and 455 mg/dL). Individual glucose concentrations were compared to mean YSI and normal HCT (42.5%) values and individual percent biases were calculated. Results demonstrated that hematocrit levels between 30 to 55% do not significantly interfere with glucose measurements.

5. Minimum sample volume studies were performed at volumes starting from 0.7 µL to 1.5 µL (i.e. 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4 and 1.5 µL) using 30 vials of test strips from two lots. Three glucose concentrations of venous blood at 63.6, 109.5 and 267.0 mg/dL, as determined by the YSI, were tested. Each sample was tested with 5 meters in singlicate (N=5 per sample at each test volume per test strip lot). Results supported a minimum sample volume of 0.9 µL.
6. Temperature and humidity operating conditions were evaluated for temperatures 50°F and 104°F (10°C and 40°C) at relative humidity ranging from 10% to 90% R.H using an environmental stat chamber (thermal-stat and humidity-stat incubator). Three glucose concentration levels of approximately 70.0, 150.0 and 250.0 mg/dL as determined by YSI were tested. At each operating condition of temperature and humidity, each sample was tested with 6 meters and one test strip lot N=6). Results supported accurate performance of the device at temperature and humidity conditions of 50°F to 104°F and 10% to 95% RH.
7. The effect of altitude on the accuracy of the device was evaluated on the Premium Blood Glucose Monitoring System using a simulated hypobaric chamber. Venous blood samples at three glucose levels of approximately 83.0, 155.0 and 365.0 mg/dL (HCT within 43%), were used. The blood samples were tested in duplicate at two altitudes; sea level and 10500 feet, with five meters and one lot of test strips. Results supported the claim that the candidate device performs accurately up to an altitude of 10,000 feet.
8. The BeneCheck Premium Glu Monitoring System is intended for home use by single person and BeneCheck Premium PRO Glu Monitoring System intended for multi-patient use in a professional healthcare setting. Disinfection efficacy studies were performed on the materials comprising the meter demonstrating the efficacy of the chosen Super Sani-Cloth germicidal disposable wipes (EPA Reg. No. 9480-4) against hepatitis B virus using HBsAg testing. Robustness studies were also performed demonstrating that there was no change in performance or in the external materials of the meter after 12,000 cleaning and disinfection cycles. The robustness studies were designed to simulate three years of single-patient use and 3 years of multiple-patient use. Labeling has been reviewed for adequate instructions on the validated cleaning and disinfection procedures.
