The document explicitly states "Mentions AI, DNN, or ML: Not Found" and describes the glucose conversion using an "onboard algorithm" without specifying it as AI/ML.
No
A therapeutic device is one that treats a disease or condition. This device, a continuous glucose monitoring system, is for monitoring and managing diabetes, not directly treating it.
Yes
The device is described as a "continuous glucose monitoring device indicated for the management of diabetes," which inherently involves monitoring and detecting levels of glucose to aid in "the detection of episodes of hyperglycemia and hypoglycemia" and "facilitating both acute and long-term therapy adjustments." This function of measuring and reporting a physiological parameter to assist in diagnosis and treatment decisions classifies it as a diagnostic device.
No
The device description explicitly states that the system consists of three main components: a sensor, a transmitter, and a display device (receiver and/or mobile app). The sensor and transmitter are physical hardware components worn on the body.
Based on the provided text, the Dexcom G6 Continuous Glucose Monitoring System is an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use explicitly states that the device is for the "management of diabetes" and is "intended to replace fingerstick blood glucose testing for diabetes treatment decisions." This indicates that the device is used to obtain information about a physiological state (glucose levels) from a sample (interstitial fluid, which is related to blood glucose) for the purpose of diagnosis, monitoring, or treatment decisions.
- Device Description: The device description explains that the sensor is inserted into subcutaneous tissue and "converts glucose into electrical current." This process of measuring a substance (glucose) in a biological sample (interstitial fluid) is characteristic of an in vitro diagnostic test.
- Comparison to Fingerstick Blood Glucose Testing: The statement that it is "intended to replace fingerstick blood glucose testing" is a strong indicator of its IVD nature, as fingerstick blood glucose testing is a well-established IVD method.
While the device is worn on the body and involves a sensor inserted into tissue, the core function is the analysis of a biological sample (interstitial fluid) to determine a physiological parameter (glucose concentration) for medical purposes. This aligns with the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Dexcom G6 Continuous Glucose Monitoring System (Dexcom G6 System) is a real time, continuous glucose monitoring device indicated for the management of diabetes in persons age 2 years and older.
The Dexcom G6 System is intended to replace fingerstick blood glucose testing for diabetes treatment decisions. Interpretation of the Dexcom G6 System results should be based on the glucose trends and several sequential readings over time. The Dexcom G6 System also aids in the detection of episodes of hyperglycemia, facilitating both acute and long-term therapy adjustments.
The Dexcom G6 System is also intended to autonomously communicate with digitally connected devices, including automated insulin dosing (AID) systems. The Dexcom G6 System can be used alone or in conjunction with these digitally connected medical devices for the purpose of managing diabetes.

Device Description
The Dexcom G6 Continuous Glucose Monitoring System consists of three main components: a sensor, a Bluetooth Low Energy (BLE) transmitter, and a BLE enabled display device (receiver and/or mobile app). The sensor is a small and flexible wire inserted into subcutaneous tissue where it converts glucose into electrical current. The transmitter is connected to the sensor and is worn on the body. It samples the electrical current produced by the sensor and converts these measurements into glucose readings using an onboard algorithm. The transmitter sends glucose data to the receiver and/or mobile app which displays the current glucose reading (updated every 5 minutes) and glucose trends (up to 12 hours) from the transmitter. The Dexcom G6 System does not require calibrations using SMBG, and the sensor life has an expected wear time of up to 10 days. The receiver and/or mobile app displays the current glucose reading and glucose trends to the user. It alerts the user when glucose levels are outside of a target zone and when other important system conditions occur.
The Dexcom G6 sensor, algorithm, receiver, and app remain unchanged, with modifications to the design of the transmitter. The proposed Dexcom G6 System is based on the same physical principles and fundamental design as the commercially-available Dexcom G6 System (DEN170088), but has modifications to physical design, software, and hardware of the transmitter. The Dexcom G6 System is designed to function as intended with either the proposed, or current G6 transmitter. The proposed G6 transmitter has the same form, fit, and function as the commercial G6 transmitter and, from the users' perspective, functions identically.

5.6 Summary of Performance Testing
The proposed Dexcom G6 System was verified and validated according to Dexcom's internal design control process and in accordance with special controls for integrated continuous glucose monitors. This testing demonstrated that the system performed according to its specifications and that the technological and performance criteria are comparable to the predicate device.

5.7 Conclusions Drawn from Performance Testing
The proposed Dexcom G6 Continuous Glucose Monitoring System is substantially equivalent to the predicate Dexcom G6 System as they are identical with regard to intended use, indications for use, and there are no differences in technological characteristics that raise different questions of safety and effectiveness. The proposed Dexcom G6 Continuous Glucose Monitoring System provides an alternative transmitter for the manufacture (Dexcom, Inc.) that meets all required performance criteria for the predicate Dexcom G6 System.
