Methods and systems for providing calibration point acceptance criteria for calibrating an analyte sensor

An analyte monitoring method comprising:

• using a light source of an analyte sensor of an analyte monitoring system to emit excitation light that interacts with indicator molecules of an analyte indicator of the analyte sensor;
• using the indicator molecules of the analyte indicator with which the excitation light interacts to emit emission light;
• using the analyte sensor to generate sensor data indicative of an amount or concentration of an analyte in proximity to the analyte indicator, wherein using the analyte sensor to generate the sensor data comprises using a photodetector of the analyte sensor to generate a measurement indicative of a level of the emission light emitted by the indicator molecules;
• using a transceiver interface device of the analyte sensor to convey the sensor data;
• using a sensor interface device of a transceiver of the analyte monitoring system to receive the sensor data conveyed by the analyte sensor;
• using the transceiver to receive a first reference analyte measurement (RM1);
• using a processor of the transceiver to determine that the RM1 is unexpected;
• after determining that the RM1 is unexpected, using the transceiver to receive a second reference analyte measurement (RM2);
• using the processor of the transceiver to use the sensor data to calculate a first sensor analyte measurement (SM1) without the RM1 as a calibration point;
• using the processor of the transceiver to use the sensor data to calculate a second sensor analyte measurement (SM2) with the RM1 as a calibration point;
• using the processor of the transceiver to determine that the RM2 is unexpected, wherein determining that the RM2 is unexpected comprises comparing the RM2 with the SM1 and comparing the RM2 with the SM2;
• after determining that the RM2 is unexpected, using the transceiver to receive a third reference analyte measurement (RM3);
• using the processor of the transceiver to accept one or more of the RM2 and the RM3 as calibration points;
• and
• using the processor of the transceiver to calibrate the analyte sensor using at least one or more of the RM2 and the RM3 as calibration points.
