Sensitivity calibration of in vivo sensors used to measure analyte concentration
First Claim
1. A method, comprising:
- determining a sample lot sensitivity associated with sensors in a manufacturing lot;
selecting a sensor in the lot;
for the selected sensor, determining one or more sensor-specific correction factors;
determining a sensor-specific sensitivity for the selected sensor based on the one or more sensor-specific correction factors;
updating a sensor code based on the sensor-specific sensitivity; and
calibrating analyte level data obtained by the selected sensor based on the updated sensor code.

Abstract
Methods, devices, systems, and computer program products are provided to improve sensitivity calibration of an in vivo analyte sensor and usability of an associated analyte monitoring system. In certain embodiments, methods are provided that improve the user experience of using an analyte monitoring system. Certain embodiments of the present disclosure include features that reduce the amount of calibration or re-calibration performed by the analyte monitoring system. More specifically methods of using a suspect calibration attempt to avoid having to recalibrate by adjusting the calibration or mitigating effects of sensor signal attenuation that caused the calibration attempt to be suspect are provided. Additional features are disclosed.
