Patent ID: 8788006

Claim:
A method for calibrating a substantially continuous analyte sensor, the method comprising: receiving a sensor data stream comprising one or more sensor data points from a substantially continuous analyte sensor; receiving reference data comprising one or more reference data points from a reference analyte monitor; using a processor module to form at least two matched data pairs by matching reference analyte data to substantially time corresponding sensor data; using the processor module to form a calibration set comprising the at least two matched data pairs; using the processor module to create a conversion function based on the calibration set; using the processor module to convert sensor data into calibrated sensor data using the conversion function; subsequently receiving an additional reference data point and creating a new matched data pair using the additional reference data point; using the processor module to evaluate the calibration set with the new matched data pair to ensure the calibration set has substantially distributed high and low matched data pairs over a predetermined time range; and using the processor module to subsequently modify the conversion function based on the evaluation.
