VivaChek™ Fad Blood Glucose Monitoring System is intended to quantitatively measure the glucose concentration in fresh capillary whole blood samples drawn from the fingertips. It is intended for use by persons with diabetes at home as an aid to monitor the effectiveness of diabetes control. It is not intended for neonatal use or for the diagnosis of or screening for diabetes. This system is intended for self-testing outside the body (in vitro diagnostic use), and should only be used by a single person and should not be shared.

VivaChek™ Fad Sync Blood Glucose Monitoring System consists of VivaChek™ Fad Sync Blood Glucose Meter and the VivaChek™ Fad Blood Glucose Test Strips. The glucose meter and test strips are packaged separately.
VivaChek Fad Control Solution, VivaChek Lancing Device, VivaChek Lancets are required for use but not included in meter box or test strips box and should be purchased separately. The VivaChek Fad Control Solution is for use with the above meter and test strip as a quality control check to verify that the meter and test strip are working together properly, and that the test is performing correctly. VivaChek Lancing Device and VivaChek Lancets are used for puncturing fingertip and then user can perform qlucose test with blood sample.
VivaChek™ Fad Blood Glucose Monitoring System, VivaChek™ Fad Smart Blood Glucose Monitoring System and VivaChek™ Fad Sync Blood Glucose Monitoring System are designed to quantitatively measure the glucose concentration in fresh capillary whole blood from the fingertip. The ducose measurement is achieved by using the amperometric detection method. The test is based on measurement of electrical current caused by the reaction of the glucose with the reagents on the electrode of the test strip. The blood sample is pulled into the tip of the test strip through capillary action. Glucose in the sample reacts with glucose dehydrogenase and the mediator. Electrons are generated, producing a current that is positive correlation to the glucose concentration in the sample. After the reaction time, the glucose concentration in the sample is displayed.
Here's a breakdown of the requested information based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The document mentions meeting "FDA SMBG OTC Guidance and industry standards" for clinical performance. A specific detailed table of acceptance criteria and reported performance is not explicitly provided in the excerpt. However, based on the context of Blood Glucose Monitoring Systems, the primary acceptance criteria would relate to the accuracy of glucose readings compared to a reference method. The document states that the clinical studies data showed that the clinical performance met the FDA SMBG OTC Guidance, implying the device successfully passed these criteria. Without the specific guidance document referenced, a detailed table cannot be created from this text alone.
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the numerical sample size used for the test set in the clinical studies. It mentions "non-professional, inexperienced lay persons" were used for user evaluations.
- Data Provenance: The studies were conducted by Vivachek Biotech (Hangzhou) Co., Ltd, located in Zhejiang, China. The document does not explicitly state if the data was retrospective or prospective, but clinical studies (user evaluations) generally imply prospective data collection in a controlled environment.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not provided in the document. For blood glucose monitoring systems, the ground truth is typically established using a laboratory reference method (e.g., YSI analyzer), rather than expert consensus on interpretation.
4. Adjudication Method for the Test Set
This information is not provided in the document. Given that the ground truth for blood glucose is typically a laboratory reference measurement, adjudication by experts wouldn't be directly applicable in the same way it would be for image-based diagnostics.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance
This is not applicable to a Blood Glucose Monitoring System. MRMC studies are relevant for AI in diagnostic imaging where human readers interpret cases. This device is a direct measurement system.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
The device itself is a standalone system for glucose measurement. The "study" here refers to the overall performance of the device in the hands of the intended users. The clinical studies (user evaluations) assess the device's performance when used by individuals (humans in the loop). The "algorithm only" concept doesn't apply as it's a physical meter and test strip system.
7. The Type of Ground Truth Used
While not explicitly stated for all studies, for blood glucose monitoring systems, the ground truth for accuracy studies is typically established using a laboratory reference method (e.g., YSI Glucose Analyzer) on venous blood samples. The document implies this by stating that clinical performance met FDA SMBG OTC Guidance, which mandates comparison to such reference methods.
8. The Sample Size for the Training Set
This information is not provided. For a physical device like a blood glucose meter, there isn't a "training set" in the same sense as machine learning algorithms. The device's calibration and performance characteristics are established during its design and manufacturing process, and then validated through laboratory and clinical studies.
9. How the Ground Truth for the Training Set Was Established
Not applicable as there is no traditional "training set" for an AI algorithm here. The performance is validated against established reference methods and clinical guidelines.
§ 862.1345 Glucose test system.
(a)
Identification. A glucose test system is a device intended to measure glucose quantitatively in blood and other body fluids. Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemia, and idiopathic hypoglycemia, and of pancreatic islet cell carcinoma.(b)
Classification. Class II (special controls). The device, when it is solely intended for use as a drink to test glucose tolerance, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.
