Please remember all changes in insulin regimens must be discussed with your diabetes team first!!!  Below is information to assist you in being more informed when speaking with them.

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 up to three 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.
