1. A method of providing continuous calibration of analyte sensors, comprising:
- calibrating a first sensor using one or more processors;
receiving data associated with detected analyte levels from the first sensor; and
calibrating a second sensor with reference to one or more detected analyte levels from the first sensor using one or more processors, wherein calibrating the second sensor includes determining a scaling factor based on data from the first sensor and the second sensor, applying the scaling factor to the data from the second sensor, and determining a correlation level of data from the first sensor and from the second sensor;
wherein determining the scaling factor includes comparing the data from the first sensor with the data from the second sensor, and determining the scaling factor based on a calculated scaling factor with the lowest level of average error between the data of the first sensor and the data of the second sensor.

14. A method, comprising:
-
positioning a first sensor in fluid contact with an analyte of a patient; calibrating the first sensor using one or more processors; positioning a second sensor in fluid contact with the analyte of the patient after calibrating the first sensor; calibrating the second sensor based on data from the first sensor using the one or more processors; and removing the first sensor while retaining the second sensor in fluid contact; wherein calibrating the second sensor includes determining a scaling factor based on data from the first sensor and the second sensor, applying the scaling factor to the data from the second sensor, and determining a correlation level of data from the first sensor and from the second sensor; and
furtherwherein determining the scaling factor includes comparing the data from the first sensor with the data from the second sensor, and determining the scaling factor based on a calculated scaling factor with the lowest level of average error between the data of the first sensor and the data of the second sensor. - View Dependent Claims (15, 16, 17)
