Claim 10:
11. A method for determining if a continuous analyte sensor is reused, comprising:
receiving, by sensor electronics, sensor data from the continuous analyte sensor, the sensor electronics being configured to be operably connected to the continuous analyte sensor;
evaluating, by the sensor electronics, a plurality of risk factors associated with end of life symptoms of a sensor, the evaluating of the plurality of risk factors being based at least in part on the sensor data;
performing, by the sensor electronics, an end of life function based on the evaluating of the plurality of risk factors, the performing of the end of life function to generate a sensor profile describing the continuous analyte sensor;
determining, by the sensor electronics and based on the sensor profile, that the continuous analyte sensor is reused; and
disabling, by the sensor electronics, a display based on the sensor data, the disabling being responsive to the determining that the continuous analyte sensor is reused, wherein the plurality of risk factors comprise at least two risk factors selected from the group consisting of a number of days the continuous analyte sensor has been in use, a rate of change of sensor sensitivity, end of life noise, oxygen concentration, glucose patterns, error between reference values, and sensor values in clinical units.
