1. A method for processing sensor data, comprising:
- generating sensor data from a continuous glucose sensor, wherein the sensor data is indicative of a glucose concentration in a host;
receiving reference data from a reference glucose monitor, wherein the reference data is indicative of a glucose concentration in the host;
determining, using a processor module, a conversion function associated with the continuous glucose sensor, wherein the conversion function comprises a first baseline value;
testing the conversion function using one or more predetermined criteria; and
wherein if the conversion function fails one or more of the predetermined testing criteria, then modifying the first baseline value to obtain a second baseline value using predetermined baseline information without reference data obtained from an in vitro self-monitoring blood glucose test after implantation in vivo.

9. A system for processing sensor data, comprising:
-
a continuous glucose sensor configured to provide sensor data indicative of a glucose concentration in a host; and a processor module configured to determine a conversion function associated with the continuous glucose sensor, wherein the conversion function comprises using predetermined baseline information to guide or validate the conversion function, wherein the conversion function comprises a sensitivity value and a first baseline value, test the conversion function using one or more predetermined criteria, and modify the first baseline value if the conversion function fails one or more of the predetermined test criteria, and wherein the first baseline value is modified to obtain a second baseline value using predetermined baseline information without reference data obtained from an in vitro self-monitoring blood glucose test after implantation in vivo, and wherein the processor module is configured to process the sensor data using the modified conversion function comprising the second baseline value. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
