1. A method of using two or more pairs of sensor elements to monitor a reliability of a blood glucose sensor, the method comprising:
- determining a metric and/or indicator of said reliability of said blood glucose sensor in providing blood glucose measurements based, at least in part, on an observed trend associated with said blood glucose sensor, and wherein said metric and/or indicator is further based, at least in part, on a correlation between output signals of said two or more pairs of sensor elements,wherein said correlation between output signals is based, at least in part, on a correlation value for each pair of sensor elements of said two or more pairs of sensor elements; and
providing a signal to indicate replacement of said blood glucose sensor based, at least in part, on said metric and/or indicator.
