2. Sample Sizes and Data Provenance:
- Test Set Sample Sizes:
- Within-run Precision: For each of 5 glucose concentrations, 5 strip lots, and 10 meters, there were 10 measurements per strip lot per meter. This totals 5 * 5 * 10 * 10 = 2500 measurements. (The text states "a total of 100 measurements per glucose concentration", which seems to contradict the previous sentence unless it's per meter type across strip lots, or a summary. Taking the more detailed description, it's 2500 total).
- Day-to-day Precision: For each of 3 control levels, 1 strip lot (per glucose level, so effectively 3 lots used in total), and 10 meters, measured once per day over 20 days. This totals 3 * 1 * 10 * 20 = 600 measurements per each of the three levels, for a grand total of 1,800 measurements.
- Linearity/Assay Reportable Range: 9 (or 10) glucose samples, each analyzed 5 times using 3 lots of test strips. This would be 9 (or 10) * 5 * 3 = 135 to 150 measurements.
- System Accuracy Study (Technician vs YSI):
- Fingertip samples: 200 participants (collected and tested twice by themselves, and once by healthcare professional).
- Contrived samples: 20 samples.
- Total sample comparisons to YSI for technician: 171 (≥75 mg/dL) + 47 (<75 mg/dL) = 218 data points.
- Total sample comparisons to YSI for user: 162 (≥75 mg/dL) + 38 (<75 mg/dL) = 200 data points.
- Alternate Site Test: A total of 100 volunteer samples. For each alternate site (Palm, Forearm, Upper Arm, Thigh, Calf), there were 5 samples < 75 mg/dL and 95 samples >= 75 mg/dL, for both professional and lay users.
- Hematocrit Study: Five measurements for each combination of glucose concentration and hematocrit level (specific total N not given, but glucose range 21-529 mg/dL and hematocrit range 10-70%).
- Altitude Study: Three lots of test strips and three meters were used (specific total N not given, but 3 glucose concentrations).
- Temperature and Humidity Studies: Three test strip lots, three glucose concentrations, twelve combinations of temp/humidity, replicates of three for each combination/glucose/meter (specific total N not given).
- Interference Studies: Whole blood from healthy volunteers (exact number of volunteers not specified, but multiple glucose levels and interferent concentrations tested).
- Data Provenance: The document does not explicitly state the country of origin for the clinical study data or whether it was retrospective or prospective. However, given the manufacturer is based in Korea (Republic of Korea), it is highly probable the studies were conducted there. The studies appear to be prospectively designed clinical and analytical performance studies conducted specifically for this submission.
3. Number of Experts and Qualifications for Ground Truth: No specific number of experts are explicitly stated as establishing the ground truth for the test set in the way one might for diagnostic imaging studies.
- For the analytical and system accuracy studies, the "ground truth" was established by laboratory reference methods, specifically the YSI 2300 Glucose analyzer for glucose measurements. The YSI 2300 is calibrated using a NIST traceable glucose standard, implying a highly accurate and standardized method for ground truth determination.
- For the usability study, "untrained lay users" were involved, but their assessment was on the "readability of the labeling" and "ease of use," not on establishing diagnostic ground truth.
4. Adjudication Method for the Test Set: Not applicable. The ground truth for the glucose measurements was established by a single, highly accurate laboratory reference method (YSI 2300), not through a consensus or adjudication process among multiple human experts.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study: No, an MRMC comparative effectiveness study was not done. The studies assessed the standalone performance of the device (both technician and lay user operated) against a reference method. There is no comparison of "human readers improve with AI vs without AI assistance" as this is a blood glucose meter, not an AI-assisted diagnostic imaging device for human interpretation.
6. Standalone (Algorithm Only) Performance: Yes, standalone performance was done for the device in the context of a blood glucose meter. The "Technician vs YSI" data directly represents the standalone performance of the device when operated by a trained professional against the gold standard (YSI). The "Lay User vs YSI" data represents the performance when operated by the intended end-user.
7. Type of Ground Truth Used:
The primary ground truth used throughout the performance studies (precision, linearity, system accuracy, alternate site testing, hematocrit, altitude, temperature/humidity, interference) was laboratory reference method measurements obtained from the YSI 2300 Glucose analyzer, which is calibrated using a NIST traceable glucose standard. This is a highly objective and quantitative ground truth.
8. Sample Size for the Training Set: The document does not specify a separate "training set" sample size. For medical devices like blood glucose meters, the development and calibration ("training") of the device's algorithms or underlying chemical reactions often occur prior to these validation studies. These studies primarily serve as external validation or "test sets" to demonstrate the final product's performance. The information provided heavily details these validation studies.
9. How Ground Truth for the Training Set Was Established: As above, specific details on a "training set" and its ground truth establishment are not provided in this 510(k) summary. The development process would typically involve extensive internal testing and calibration against reference methods (like the YSI 2300) to fine-tune the device's performance before formal validation studies are conducted. The traceability to the YSI 2300 analyzer and NIST traceable glucose standard suggests that this highly accurate reference method would have been central to any internal calibration or "training" process.

- Performance Characteristics
1. Analytical performance
A. Precision/Reproducibility
(1) Within-run Precision
Within-run precision was evaluated by analyzing venous whole blood samples spiked to five different glucose concentrations. The hematocrit of all samples was between 35 and 50%. Five different lot numbers of test strips and ten meters were used in the study and each of the samples was measured ten times per strip lot number per meter for a total of 100 measurements per glucose concentration. The samples were analyzed by one operator in one day.
| Interval | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| Glucose concentration | 30~50 | 51~110 | 111~150 | 151~250 | 251~400 |
| YSI (mg/dL) | 44 | 96 | 127 | 226 | 323 |
| Mean | 45.2 | 97.6 | 129.1 | 228.3 | 326.1 |
| STD(mg/dL) | 2.4 | 3.1 | 4.1 | 6.9 | 7.3 |
| CV (%) | 5.2 | 3.1 | 3.2 | 3.0 | 2.2 |
(2) Day to day precision
Day to day precision was evaluated by analyzing control samples at three different concentrations. Three lot numbers of test strips (one per glucose level) and ten meters were used in the study. Each of the controllevels was measured once per day over twenty. Each of the control levels was measured once per strip lot number per meter. In total, 600 measurements were taken for each of the three levels. Results are summarized below:
| Interval | 1 | 2 | 3 |
|---|---|---|---|
| Glucose concentration | 30~50 | 96~144 | 280~420 |
| YSI, mg/dL | 43 | 108 | 304 |
| Mean | 42.6 | 108.4 | 303.8 |
| STD(mg/dL) | 2.3 | 3.4 | 8.6 |
| CV(%) | 5.5 | 3.2 | 2.8 |
{4}------------------------------------------------
B. Linearity/assay reportable range
CERACE
.
MEDISYS
The sponsor evaluated the linearity of the meter by preparing a series of 9 glucose samples, following the dilution scheme in CLSI EP6-A, and producing target values of 11, 52, 89, 157, 234, 310, 386, 461, 531, and 607 mg/dL.
·Each of the ten levels was analyzed five times using three lots of test strips. All samples were also tested on the YSI 2300 analyzer. Linear regression of the data produced the following:
| Strip Lot | Slope | Intercept | Corr Coeff ( $r^2$ ) |
|---|---|---|---|
| 1 | 0.9896 | 1.4433 | 0.9995 |
| 2 | 0.9786 | 2.4223 | 0.9997 |
| 3 | 0.9782 | 4.4741 | 0.9992 |
The results of the study support the sponsor's claimed glucose measurement range of 20 - 600 mg/dL.
C. Traceability, Stability, Expected values (controls, calibrators, or methods)
The CERA-CHEK 1070 Blood Glucose Monitoring System is traccable to the YSI 2300 Glucose analyzer which is calibrated using the YSI 2747 Glucose Standard which is a NIST traceable glucose standard.••
Test strip shelf-life stability (closed vial) was assessed in an accelerated study with real time studies ongoing, The protocols and acceptance criteria were reviewed and found to be acceptable. The testing supported the claimed shelf life of 24 months when stored at 1- 32° C and 10-85% RH.

CERAGEM
MEDISYS
The measuring range of the device is 20 - 600 mg/dL. This range was validated by the linearity study.
E. Analytical specificity
The sponsor performed interference studies in accordance with CLSI EP7-A. Testing was performed in parallel (control samples vs. test samples) to minimize the effects of glucose metabolism. Whole blood was drawn into K3-EDTA anticoagulant tubes from healthy volunteers who were not on any medications. The glucose levels tested were 64, 151, and 257 mg/dL. The highest level was achieved by spiking. A low and high concentration of each potential interferent was then tested at each glucose level. The following substances were found not to interfere at the concentrations listed:
| Substance | No interference up to: |
|---|---|
| Acetaminophen | 6 mg/dL |
| Ascorbic acid | 4 mg/dL |
| Dopamine | 5 mg/dL |
| Ibuprofen | 40 mg/dL |
| Metformin | 4 mg/dL |
| Methyldopa | 5 mg/dL |
| Salicylic acid | 50 mg/dL |
| Uric acid | 10 mg/dL |
| Bilirubin | 4 mg/dL |
| Triglyceride | 1,500 mg/dL |
| Cholesterol | 500 mg/dL |
| Creatinine | 10 mg/dL |
| Galactose | 100 mg/dL |
| Gentisic acid | 2 mg/dL |
| Glutathione | 3 mg/dL |
| Hemoglobin | 20 g/dL |
| L-dopa | 4 mg/dL |

| Maltose | 100 mg/dL |
|---|---|
| Sodium | 150 mmol/L |
| Tolbutamide | 64 mg/dL |
| Tolazamide | 5 mg/dL |
| Xylose | 10 mg/dL |
| Mannitol | 800 mg/dL |
| Sorbitol | 100 mg/dL |
| Xylitol | 100 mg/dL |
| Lactitol | 100 mg/dL |
| Isomalt | 100 mg/dL |
| Maltitol | 100 mg/dL |
| Hydrogenated starchhydrolysates | 100 mg/dL |
The sponsor has the following limitations in their labeling
- � High concentrations of dopamine, methyldopa, and Tolazamidc may cause inaccurate test results
- . Do not use during or soon after xylose absorption testing. Xylose (>10mg/dL) in the blood will cause interference.
2. Comparison studies
A. Method comparison with predicate device
For the user performance study, 200 participants collected and tested twice their own fingerstick sample in single measurements on the CERA-CHEK 1070 BGMS. The healthcare professional tested the collected samples of 200 participants and 20 contrived samples on CERA-CHEK 1070 BGMS. Within five minutes, fingerstick sample was collected from each participant by a healthcare professional for the system accuracy study and was tested on the YSI 2300 reference analyzer.

3. Other Supportive Instrument Performance Characteristics Data Not Covered In the " Performance Characteristics" Section above
A. Hematocrit study
MEDISYS
The effect of different hematocrit levels was evaluated using venous whole blood samples with hematocrit levels across the claimed range and altered to glucose concentrations from 21 - 529 mg/dL. There were five measurements for each combination of glucose concentration and hematocrit level. The results demonstrated that CERA-CHEK 1070 Blood Glucose Monitoring System produces accurate results over the claimed hematocrit range of 10 - 70%.
B. Altitude study
A study was conducted to evaluate the effect of altitude on the device. In this evaluation, venous blood at glucose concentrations of approximately 100. 200, and 300 mg/dL was tested using a decompression chamber to simulate the effects of altitude. Three lots of test strips and three meters were used. Each blood sample was also tested by the YSI 2300 analyzer. The meter readings obtained were compared to the YSI method and the percent bias was determined at each level against the YSI results demonstrated that the CERA-CHEK 1070 Blood Glucose Monitoring System produces accurate results at altitudes up to 13,200 feet.
C. Temperature and humidity studies
In this study, three test strip lots were tested on three glucose concentrations (approximately 45, 120, and 300 mg/dL) at twelve combinations of temperature and humidity. Each combination of environmental conditions / glucose concentration / meter was tested in replicates of three. The temperatures tested ranged from a low of 10.0° C to a high of 41.2° C. The relative humidity tested ranged from 10.3% -86.6%. Glucose concentrations were verified by the YSI reference method. The bias relative to the reference method was acceptable to support the claim that temperatures from 10 – 40° C (50 – 104° F) and relative humidity from 10 - 85% do not significantly affect the glucose results.
D. Infection Control Studies
The CERAGEM MEDISYS CERA-CHEK 1070 Blood Glucose Monitoring System is intended for singlepatient use only. Disinfection efficacy studies were performed on the materials comprising the meter and lancing device by an outside commercial testing facility demonstrating complete inactivation of hepatitis B virus (HBV) with the chosen disinfectant, CaviWipes (EPA Registration Number 46781-8).

studies were also performed by the sponsor demonstrating that there was no change in performance or external materials for the meter and lancing device after 1825 cleanings and 1825 disinfection steps with CaviWipes. 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.
E. Usability Study
A usability study was performed to assess the readability of the labeling by recruiting untrained lay users who were provided with the test kit and labeling. These lay users also completed a questionnaire regarding the clarity of the instructions and the ease of use of the majority of the users responded that they understood the instructions and were able to successfully operate the device.
