Detection and correction of analyte indicator changes

Sensors, systems, and methods for detecting and correcting changes in an analyte indicator of an analyte sensor. The analyte indicator may be configured to exhibit a first detectable property that varies according to an analyte concentration and a degree of degradation of the analyte indicator. The analyte sensor may also include a degradation indicator configured to exhibit a second detectable property that varies according to a degree of degradation of the degradation indicator. The sensor element may (i) generate an analyte measure based on a first detectable property displayed by the analyte indicator and (ii) generate a degradation measure based on a second detectable property displayed by the degradation indicator. The analyte sensor may be part of a system that further includes a transceiver. The transceiver may calculate an analyte level using the analyte and the degradation measure. 用于检测和修正分析物传感器的分析物指示剂的变化的传感器、系统和方法。所述分析物指示剂可以配置为显示第一可检测性质，其根据分析物浓度和分析物指示剂降解的程度而变化。分析物传感器还可以包括降解指示剂，所述降解指示剂配置为显示第二可检测性质，其
