Does the Dexcom G6 Transmitter require calibration?


Living with diabetes requires constant monitoring of blood glucose levels to maintain health and prevent complications. Traditional methods involve regular finger pricks, but technological advancements have introduced continuous glucose monitoring (CGM) systems like the Dexcom G6 Transmitter, revolutionizing diabetes management.

What is Dexcom G6 Transmitter?

The Dexcom G6 Transmitter is a pivotal component of the Dexcom G6 CGM system, designed to provide real-time glucose readings without the need for finger pricks. This FDA-approved device offers a more convenient and comprehensive approach to monitoring blood sugar levels.

Understanding Continuous Glucose Monitoring (CGM)

CGM systems like Dexcom G6 utilize a sensor inserted under the skin to measure glucose levels in interstitial fluid. These readings are transmitted wirelessly to a receiver or compatible smart device, providing users with continuous insight into their glucose trends.

How Does Dexcom G6 Transmitter Work?

The Dexcom G6 Transmitter works in conjunction with a sensor and receiver/smartphone to deliver accurate and timely glucose readings. Once the sensor is inserted into the skin, the transmitter wirelessly communicates with the sensor to capture glucose data. Users can conveniently view this information on their receiver or smartphone.
