The summary describes a standard electrochemical blood glucose and ketone monitoring system. There is no mention of AI or ML in the device description, intended use, or performance studies. The technology described is based on enzymatic reactions and electrical current measurement.
No
The device is an in vitro diagnostic (IVD) device used for monitoring glucose and ß-ketone levels, not for treating or preventing a disease.
No
The device is explicitly stated as "not intended for neonatal use or for the diagnosis of or screening for diabetes." Instead, it is an "aid to monitor the effectiveness of diabetes control." While it measures quantitative values, it is for monitoring, not for initial diagnosis or screening.
No
The device description explicitly states it is comprised of a meter (VGM200) and test strips (VGS01 and VKS01), which are hardware components. The system measures glucose and ketones in blood samples using an amperometric principle, which requires physical interaction with the sample and hardware.
Yes, this device is an IVD (In Vitro Diagnostic).
The "Intended Use / Indications for Use" section explicitly states: "This system is intended for self-testing outside the body (in vitro diagnostic use)".
Furthermore, the device measures analytes (glucose and beta-hydroxybutyrate) in a biological sample (fresh capillary whole blood) to provide information about a person's health status (monitoring the effectiveness of diabetes control), which is the definition of an in vitro diagnostic device.

Device Description
VivaChek™ Blood Glucose and β-Ketone Monitoring System (Model: VGM200) is designed to quantitatively measure the glucose and/or ß-ketone concentration respectively in fresh capillary whole blood samples drawn from the fingertips.
The test principle of the ß-ketone is based on the amperometric detection of ß-hydroxybutyrate (also known as 3-hydroxybutyrate) in whole blood. β-hydroxybutyrate is converted by the enzyme ß-hydroxybutyrate dehydrogenase to acetoacetate. The magnitude of electrical current resulting from this enzymatic reaction is proportional to the amount of ß-hydroxybutyrate present in the sample.
VivaChek™ Blood Glucose and ß-Ketone Monitoring System (Model: VGM200) contains Bluetooth Low Energy (BLE), it complies with US federal quidelines, Part 15 of the FCC Rules for devices with RF capability. Refer to the relative FCC Test Reports in this submission.

Brief Discussion of Non-Clinical Studies:
Above non-clinical (laboratory) studies were performed on the VivaChek™ Blood Glucose and ß-Ketone Monitoring System in accordance with the corresponding study protocols, and the test results indicated that the acceptance criteria were met. Therefore the ketone performances from these non-clinical (laboratory) studies were acceptable.
Brief Discussion of Clinical Study:
User evaluation study was conducted in accordance with the User Evaluation Study Protocol on VivaChek™ Blood Glucose and ß-Ketone Monitoring System. Study results indicated that non-professional, inexperienced lay persons were able to obtain ß-ketone readings when using the VivaChek™ Blood Glucose and β-Ketone Monitoring System. In addition, the participated lay persons were questioned and responded as satisfied with the ease of operation by following User Manual and the overall ketone measurement performance of the VivaChek™ Blood Glucose and β-Ketone Monitoring System.
Conclusion:
The non-clinical (laboratory) studies and clinical (user evaluation) study results have demonstrated that the VivaChek™ Blood Glucose and β-Ketone Monitoring System is safe, effective and easy-to-use, besides it demonstrated that the VivaChek™ Blood Glucose and B-Ketone Monitoring System meets applicable CLSI guidelines, and also based on the similarities described in the table of Comparison to Predicate Device on Technological Characteristics in this 510(k) summary.
