Systems and methods of use for continuous analyte measurement of a host's vascular system are provided. In some embodiments, a continuous glucose measurement system includes a vascular access device, a sensor and sensor electronics, the system being configured for insertion into communication with a host's circulatory system.
1. A method for evaluating a change in a sensitivity of an implanted analyte sensor over a predetermined time period, comprising: receiving sensor data from an analyte sensor implanted in a host, wherein the implanted sensor is configured to generate sensor data, wherein the sensor data comprises on
1. A method for evaluating a change in a sensitivity of an implanted analyte sensor over a predetermined time period, comprising: receiving sensor data from an analyte sensor implanted in a host, wherein the implanted sensor is configured to generate sensor data, wherein the sensor data comprises one or more sensor analyte values measured in a biological sample of a host;intermittently calculating a sensitivity of the analyte sensor; andevaluating, using an electronic device, a change in sensitivity by evaluating a plurality of time-spaced sensitivity calculations over a predetermined time period, wherein evaluating a change in sensitivity is based at least in part on using a priori sensitivity information throughout a sensor session, wherein the a priori sensitivity information comprises sensitivity information that is used to generate an expected sensitivity profile that is a function of time. 2. The method of claim 1, wherein the predetermined time period is less than or equal to about 30 minutes. 3. The method of claim 1, wherein the predetermined time period is less than or equal to about 20 minutes. 4. The method of claim 1, wherein the predetermined time period is less than or equal to about 10 minutes. 5. The method of claim 1, wherein evaluating a change in sensitivity comprises evaluating at least two sensitivity measurements during the predetermined time period. 6. The method of claim 5, further comprising averaging and/or filtering the at least two sensitivity measurements prior to evaluating the at least two sensitivity measurements. 7. The method of claim 1, wherein evaluating a change in sensitivity comprises comparing the change in sensitivity with one or more criteria. 8. The method of claim 7, further comprising using a most recent sensitivity calculation evaluated to calibrate the analyte sensor when the change in sensitivity meets one or more criteria. 9. The method of claim 7, further comprising not using a most recent sensitivity calculation evaluated to calibrate the analyte sensor when the change in sensitivity does not meet one or more criteria. 10. The method of claim 1, wherein evaluating a change in sensitivity is iteratively performed on the plurality of time-spaced sensitivity calculations over the predetermined time period. 11. The method of claim 1, wherein the predetermined time period is at least about 30 minutes. 12. The method of claim 1, wherein the predetermined time period is at least about 60 minutes. 13. The method of claim 1, wherein the predetermined time period is at least about 120 minutes. 14. The method of claim 1, wherein evaluating a change in sensitivity comprises evaluating all sensitivity calculations over a sensor session.
