Continuous Glucose Monitoring Systems...
A Continuous glucose monitor is a small device warn under the skin that uses interstitial fluid to monitor blood glucose levels. It then transmits readings to a receiver and allows a person with diabetes to have a guide to what blood glucose levels may be at a given time and whether they are expected to rise or fall in the near future.
What is the difference between testing and using a Continuous Glucose Monitor?
Glucometers are portable devices that read glucose levels from a blood sample that is placed on a tiny test strip. Test strips are discarded after a single use. Some meters store a limited number of glucose results in memory. The results can be downloaded into a computer.
A glucose sensor is a tiny electrode that is inserted under a patient’s skin (subcutaneous tissue) and continuously records glucose levels around the clock. The sensor is worn for between three to seven days before it is discarded and replaced by the patient. Glucose readings are transmitted to a monitor or insulin pump where the values are displayed. Trend reports and charts can be viewed after data is downloaded to a computer.

I have been T1D for 16 years and for the past year I have been using the Dexcom G4. This amazing piece of technology has drastically changed my life with diabetes. The accuracy is incredible and I have a level of confidence now that I never had before. Always knowing where I'm at and where I'm going truly allows me to live a more "normal" life. The cost is high but to me its worth every penny.
