Classification: CPC G  A | IPC A  G

Claim 0:
1. A system for determining if a continuous analyte sensor is reused, the system comprising sensor electronics configured to be operably connected to a continuous analyte sensor, the sensor electronics configured to:
receive sensor data from the continuous analyte sensor;
evaluate a plurality of risk factors associated with end of life symptoms of the continuous analyte sensor the evaluating of the plurality of risk factors being based at least in part on the sensor data;
perform 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;
determine, based on the sensor profile, that the continuous analyte sensor is reused; and
responsive to the determining that the continuous analyte sensor is reused, disable a display based on the sensor data, 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.
