Intended Use
The Rightest Blood Glucose Monitoring System is intended for in vitro diagnostic use (outside of body). It is indicated to be used by professional healthcare personnel or people with diabetes at home to measure the glucose concentration for aiding diabetes management. The glucose concentration is measured with quantitative capillary whole blood from fingertip, palm and forearm by using Rightest Blood Glucose Monitoring System. This test device is not intended for testing neonate blood samples.
Device Story
System measures glucose in capillary whole blood; utilizes amperometric assay with glucose oxidase enzyme and potassium ferricyanide mediator. User applies blood sample to test strip; meter measures electrical current proportional to glucose concentration; converts to plasma-equivalent result. Used by professionals or patients at home. Includes meter, test strips, code key, check key, control solutions, and lancing device. Code key calibrates meter for specific strip batch; check key verifies meter status. Output displayed on meter; aids diabetes management decisions. Modification reduces read time to 5 seconds and sample volume to 0.6 uL.

ISO 15197: In vitro diagnostic test systems - Requirements for blood-glucose monitoring systems for self-testing in managing diabetes mellitus.
# L. Test Principle:
The glucose oxidase and potassium ferrocyanide in the strip react with the glucose in the sample to produce an electrical current which is proportional to the amount of glucose in the sample. The meter measures the current and converts it to the corresponding glucose concentration.
# M. Performance Characteristics (if/when applicable):
# 1. Analytical performance:
# a. Precision/Reproducibility:
Precision was performed using CLSI EP5-A: Evaluation of Precision Performance of Clinical Chemistry Devices. Three levels of samples were used to establish precision of the assay on blood samples. Each sample was analyzed on 5 Bionime glucose meters with each meter tested 10 times, for a total of 50 measurements:
| Blood Sample | 1 | 2 | 3 |
| --- | --- | --- | --- |
| N | 50 | 50 | 50 |
| Mean (mg/dL) | 91.9 | 197.5 | 356.4 |
| SD (mg/dL) | 1.7 | 3.2 | 5.8 |
| %CV | 1.8 | 1.6 | 1.6 |
Five levels of control materials over the claimed assay range were used to establish total precision of the assay. Each control solution was analyzed on 5 Bionime glucose
{3}
meters by one operator in duplicate over 20 consecutive days using two lots of test strips, for a total of 400 measurements:
| Control Solution | 1 | 2 | 3 | 4 | 5 |
| --- | --- | --- | --- | --- | --- |
| N | 400 | 400 | 400 | 400 | 400 |

| %CV | 2.5 | 1.9 | 1.9 | 1.8 | 1.7 |
b. Linearity/assay reportable range:
The linearity of the device was demonstrated by comparing 14 prepared whole blood samples on the Rightest and a glucose reference method; each level was tested in quadruplicate by two lots of test strips. The 14 samples covered the claimed clinical range of the meter (23.5 - 570 mg/dL). Analysis of the results showed a linear relationship between the Rightest and the reference method: Lot 1 y = 0.987x - 4.2, R² = 0.999, Lot 2 y = 0.987x - 4.9, R² = 0.999. The reportable range of the Rightest meter is 20 - 600 mg/dL.
c. Traceability, Stability, Expected values (controls, calibrators, or methods):
The control materials supplied for this device were cleared under k012431. The sponsor established traceability to a reference method in k042678.
d. Detection limit:
20 mg/dL: see linearity studies above. For values below 20 mg/dL the meter reads 'LO'.

The sponsor evaluated the effect of hematocrit levels 20 – 70% on whole blood samples spiked with eight hematocrit levels for three levels of glucose (low (40-70 mg/dL), medium (110-200 mg/dL) and high (200-400 mg/dL). The values generated were compared with the glucose values from a reference method. Based on the deviation for glucose concentrations versus 40% hematocrit, the data supports the sponsor’s claimed range of hematocrit levels between 30-55%. The results are summarized below.

2. Comparison studies:
a. Method comparison with predicate device:
A consumer study was performed with 139 lay-users and a technician to see if glucose readings from the forearm, palm and fingertip were comparable to a laboratory glucose reference method. Each participant performed their own fingerstick and tested their blood using the instructions in the User's Guide. These clinical samples ranged from 29 – 482 mg/dL. Linear regression analysis of the data yielded the results below:
| | Fingerstick vs. Reference Method | Palmstick vs. Ref. Method | Palmstick vs. Fingerstick | Armstick Ref. Method | Armstick vs. Fingerstick |
| --- | --- | --- | --- | --- | --- |
| N | 139 | 139 | 139 | 139 | 139 |
| Regression | y = 0.99x – 1.36 | y = 0.98x + 2.57 | y = 0.98x + 5.05 | y = 0.97x – 3.93 | y = 0.96x + 0.47 |
| r value | 0.989 | 0.990 | 0.994 | 0.990 | 0.982 |
| | | | | | |
| Samples < 75 mg/dL within ±15 mg/dL | 26/26 (100%) | 26/26 (100%) | 25/26 (96%) | 26/26 (100%) | 25/26 (96%) |
| Samples ≥ 75 mg/dL | 110/113 (97%) | 110/113 (97%) | 110/113 (97%) | 108/113 (96%) | 105/113 (93%) |

b. Matrix comparison:
This system is cleared for use with fingerstick, palm, and forearm capillary whole blood samples. The meter’s software adjusts the whole-blood glucose reading to a plasma-equivalent reading.
3. Clinical studies:
a. Clinical Sensitivity:
See method comparison section above.
b. Clinical specificity:
Not applicable.
c. Other clinical supportive data (when a. and b. are not applicable):
The sponsor provided a readability study that indicated that the user manual, strip labeling, and control solutions are at an 8th grade reading level.
4. Clinical cut-off:
Not applicable.
5. Expected values/Reference range:
The normal fasting adult glucose range for a non-diabetic listed by the sponsor is 70 – 99 mg/dL. Referenced from Diabetes Information - American Association for Clinical Chemistry (AACC) (Electronic Version).
N. Instrument Name:
Bionime Rightest Blood Glucose Monitoring System
O. System Descriptions:
1. Modes of Operation:
Each test strip is single use and must be replaced with a new strip for additional readings.
2. Software:
FDA has reviewed applicant’s Hazard Analysis and software development processes for this line of product types:
Yes ☐ X ☐ or No ☐
3. Specimen Identification:
There is no sample identification function with this device. Samples are applied directly to the test strip as they are collected.
4. Specimen Sampling and Handling:
This device is intended to be used with capillary whole blood from the finger, palm, or forearm only. Since the whole blood sample is applied directly to the test strip there are no special handling or storage issues.

5. Calibration:
A Smart Code Key is provided with each batch of test strips to calibrate the meter for that batch. No further calibrations are required of the user.
6. Quality Control:
The sponsor provides a single level of glucose control solution with this device. A second level of control solution is available for purchase but is not included in the kit. When the Check Key is inserted into the meter, the control mode is activated. This prevents control results from being stored in the internal memory. An acceptable range for each control level is printed on the test strip vial label. The user is referred to the troubleshooting section of the User's Manual if control results fall outside these ranges.
P. Other Supportive Instrument Performance Characteristics Data Not Covered In the "Performance Characteristics" Section above:
Not applicable.
Q. Proposed Labeling:
The labeling is sufficient and it satisfies the requirements of 21 CFR Part 809.10.
R. Conclusion:
The submitted information in this premarket notification is complete and supports a substantial equivalence decision.
