Can the user of a Dexcom G6 continuous glucose sensor dose insulin based on the sensor value without confirming with a fingerstick?

The ability to dose insulin based on a Dexcom G6 continuous glucose sensor value without confirming with a fingerstick is indeed supported by the design and FDA approval of the sensor. The Dexcom G6 is recognized for its accuracy and reliability, allowing users to make treatment decisions directly based on its readings. This is particularly beneficial for managing diabetes in real-time, as it provides continuous glucose monitoring that can help prevent both hyperglycemia and hypoglycemia.

The FDA has indicated that the G6 is intended for use as a replacement for fingerstick blood glucose testing for the purpose of making diabetes treatment decisions. This means that users can trust the sensor's readings for dosing insulin, which enhances the convenience and ease of managing blood glucose levels.

While it is always a good practice to confirm readings, especially if symptoms do not align with the sensor's indicated glucose level, the approval for the G6 allows for this direct reliance in most situations. This feature makes it unique compared to previous versions or other devices that may still require fingerstick verification for insulin dosing.

The choice to indicate this as the correct answer reflects the current guidelines and design purpose of the Dexcom G6, emphasizing the importance of technology in diabetes management and potentially improving patient compliance and outcomes.
