1. A system for performing a diagnostic of an analyte sensor system, comprising:

  • an analyte sensor system comprising a sensor, wherein the analyte sensor comprises a first working electrode configured to provide a first signal comprising an analyte component and a baseline component and a second working electrode configured to provide a second signal comprising a baseline component substantially without an analyte component;

    a flow control device configured to intermittently expose the analyte sensor to a biological sample and an infusion solution; and

    a processor module configured to evaluate the analyte sensor system based at least in part on the second signal, wherein the second signal comprises a signal waveform, and wherein the processor module is configured to evaluate the signal waveform for at least one of an expected shape or a pattern when the analyte sensor is exposed to at least one of the biological sample or the infusion solution.
