The Nova Max Creat eGFR Monitoring System is comprised of the Nova Max Creat eGFR Monitor and the Nova Max Creat eGFR Test Strips.
The Nova Max Creat eGFR Monitoring System is intended for in vitro diagnostic use for the quantitative measurement of creatinine and estimation of glomerular filtration rate (eGFR) in fresh capillary whole blood obtained from the fingertip of adult patients aged 18 and above. The system is intended for single patient home use by prescription only and should not be shared. It is intended for use by patients as an aid to monitor kidney function on the order of a treating healthcare professional.
The Nova Max Creat eGFR Monitoring System consists of Nova Max Create eGFR Monitor and Nova Max Create eGFR Creatinine-Test Strips. The Nova Max Creat eGFR test strips, Nova Max Creat eGFR control solution (Level 1 and Level 2), and a single-use, disposable, 21 gauge safety lancet can be purchased separately.
Nova Max Creat eGFR Monitor
The monitor is intended to be used in conjunction with the Nova Max Creat eGFR Creatinine-Test Strips to measure creatinine and calculate estimated glomerular filtration rate (eGFR) using capillary whole blood obtained from the fingertip. The hand-held monitor is lightweight, portable, utilizes a 2.8" color touchscreen display and has capability for storage (400 test samples and/or quality control samples) and review of data. The monitor is powered by a rechargeable, 3.7 V Li polymer battery.
Nova Max Creat eGFR Creatinine-Test Strips
The Nova Max Creat eGFR Creatinine-Test Strip is designed with an electrode that measures creatinine levels. Creatinine in the capillary whole blood sample mixes with the reagents in the test strip to produce an electric current. The amount of current that is produced depends on how much creatinine is in the sample. A digital readout is displayed on the monitor in 30 seconds, the eGFR is calculated using patient information and the measured creatinine level. The test strips are for single use only.
Nova Max Creat eGFR Creatinine Control Solutions
The Nova Max Creat eGFR Creatinine Control Solution is used as a quality control check to ensure that the Nova Max Creat eGFR Monitor and the Nova Max Creat eGFR Creatinine-Test Strips are working properly as a system. There are two levels of Nova Max Creat eGFR Creatinine Control Solution. Each level of control solution has a known creatinine concentration that reacts with the reagents in the test strip.

Dear Mariya Cesnulevicius:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Summary of Performance Testing
Analytical bench and clinical testing were conducted to demonstrate that the Nova Max Creat eGFR Monitoring System achieves its intended purpose at the intended use setting.
Linearity Testing
Testing was performed to validate the Nova Max Creat eGFR Monitoring System linearity. Ten (10) specimens were tested on the Nova Max Creat eGFR Monitoring System. The same specimens were analyzed on the reference method. The results met the acceptance criteria, validating the linearity of the Nova Max Creat eGFR Monitoring System across the measurement range of 0.30 mg/dL to 7.00 mg/dL.
Analytical Specificity
The analytical specificity for the Nova Max Creat eGFR Monitoring System was assessed by testing the effect of various exogenous and endogenous substances on the measurement of creatinine by the system. Whole blood samples were spiked with forty-six (46) potential interferents and the creatinine concentration was measured with the Nova Max Creat eGFR Monitoring System.
Page 2 of 7
Page 7
The test substance was considered to be an interfering substance if the absolute difference between the test value and the control value was greater than 10% for creatinine concentration higher than 2 mg/dL, and greater than ± 0.2 mg/dL if the creatinine concentration is less than 2 mg/dL.
Based upon the results, all potential interfering substances tested met the acceptance criteria and were demonstrated not to have clinical interference. No clinical interference was identified up to the test concentrations reported in Table 1.

Limits of Detection and Quantification
Testing was conducted to assess the analytical sensitivity of the Nova Max Creat eGFR Monitoring System. Blank whole blood samples were tested to estimate the limit of the blank (LoB). This value was used to select a low level of creatinine concentration to determine the LoD and LoQ. Low level samples were prepared with creatinine concentration close to the estimated low value for creatinine concentration. These samples were tested repeatedly on the Nova Max Creat eGFR Monitoring System. Samples were also tested on the reference analyzer.
The study yielded the following results for creatinine:
Limit of Blank (LoB) = 0.078 mg/dL
Limit of Detection (LoD) = 0.174 mg/dL
Limit of Quantification (LoQ) = 0.174 mg/dL

- Short sample
- Used Nova Max Creat eGFR Creatinine-Test Strips
- Incorrect test strips
- Moving during analysis
- Atypical positions
- Removing Nova Max Creat eGFR Creatinine-Test Strips during the analysis
- Double dosing
- Delayed analysis

The results of the Flex Studies were determined to meet the Acceptance Criteria and error codes were correctly generated (where applicable) as specified in the Instructions for Use Manual.
Clinical Performance
Nova Biomedical conducted a clinical study in the hands of lay users. The clinical study was conducted across two (2) sites with a total of 532 subjects. Measurements on fingerstick samples taken by lay users using the Nova Max Creat eGFR Monitoring System were compared to venous plasma creatinine results measured by laboratory operators using an IDMS traceable comparative method.
The Pearson correlation coefficient (r) between the fingerstick blood readings obtained by lay users and the corresponding comparative method readings obtained by laboratory operators was calculated using least squares linear regression and is displayed in Table 4.
Table 4, Creatinine Linear Regression Analysis Summary
| Slope: | 0.9832 |
| Y-Intercept: | 0.0073 |
| Correlation Coefficient (r): | 0.9951 |
The bias between the capillary whole blood creatinine readings from the Nova Max Creat eGFR Monitoring System and the venous plasma creatinine readings measured by the comparative method was evaluated and shown in Table 5.
Table 5, Within Clinical Study Accuracy (Bias/Bias%)
| Less than 2 mg/dL | Greater than 2 mg/dL |
|---|---|
| SD ≤ 0.2 mg/dL | CV ≤ 10% |
| 97.87% | 95.36% |
