Systems and methods for processing analyte sensor data

A method for processing sensor data from a continuous analyte monitoring system, comprising:

• initializing a sensor of a continuous analyte monitoring system implanted within a body of a host user, the sensor in electrical communication with a sensor electronics of the continuous analyte monitoring system configured to receive and process sensor data by the sensor;
• acquiring sensor data, using the sensor, to measure an analyte level in the host's body over a first interval based on a first elapsed time since the sensor was implanted;
• determining whether the sensor has been previously used in a previous sensor session or the sensor is a new sensor, wherein determining whether the sensor has been previously used comprises measuring a change in impedance of the sensor over a predetermined time period after implantation, and identifying that the measured change in impedance is substantially insignificant or levels off over at least a portion of the predetermined time period;
• upon determining the sensor is a new sensor, adjusting the acquired sensor data to compensate for sensor drift of the new sensor by applying a first set of time-dependent algorithmic functions to the sensor data associated with the first interval, wherein the first set of time-dependent algorithmic functions comprise a first boundary of acceptability including a first drift rate of sensitivity over time and/or a first drift of baseline over time;
• acquiring further sensor data, using the sensor, to measure the analyte level over a second interval based on a second elapsed time since the sensor was implanted and after the first interval;
• and
• adjusting the acquired further sensor data by applying a second set of time-dependent algorithmic functions to the sensor data associated with the second interval, wherein the second set of time-dependent algorithmic functions comprise a second boundary of acceptability including a second drift rate of sensitivity over time and/or a second drift of baseline over time,
• wherein the first and second set of time-dependent algorithmic functions comprise first and second drift compensation functions, and
• wherein the first and second drift compensation functions differ in the amount of drift compensation that they apply.
