The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.
1. A system for monitoring a glucose concentration in a host, the system comprising: a substantially continuous glucose sensor configured to produce sensor data indicative of a glucose concentration in a host;a sensor data receiving module configured to receive the sensor data from the substantially
1. A system for monitoring a glucose concentration in a host, the system comprising: a substantially continuous glucose sensor configured to produce sensor data indicative of a glucose concentration in a host;a sensor data receiving module configured to receive the sensor data from the substantially continuous glucose sensor;a reference data receiving module configured to receive reference data from an in vitro single point glucose monitor, the in vitro single point glucose monitor configured to receive a biological sample from the host and to measure a glucose concentration in the sample;a processor module in communication with the sensor data receiving module and the reference data receiving module; andcomputer readable memory comprising: instructions configured to cause the processor module to calibrate the sensor data received from the substantially continuous glucose sensor;instructions configured to cause the processor module to determine a rate of change of the calibrated sensor data;instructions configured to determine whether the rate of change is within a range of rates of change delimited by maximum normally sustainable rates of change of glucose in humans; andinstructions configured to allow the processor module to calibrate the sensor data using the reference data when the rate of change is within the range of rates of change delimited by maximum normally sustainable rates of change of glucose in humans, but not allow the processor module to calibrate the sensor data using the reference data when the rate of change is outside the range of rates of change delimited by maximum normally sustainable rates of change of glucose in humans. 2. The system of claim 1, wherein the maximum normally sustainable rates of change of glucose in humans is within a range of about +/−4 mg/dL/min. 3. The system of claim 1, wherein the substantially continuous glucose sensor is configured to be implanted in a subcutaneous space of the host. 4. The system of claim 1, wherein the sensor data is indicative of the concentration of glucose in a subcutaneous space of the host. 5. The system of claim 1, wherein instructions configured to cause the processor module to cailbrate the sensor data comprise calibrating the sensor data using the reference data comprises forming a matched data pair by matching a sensor data point of the sensor data with a time-corresponding reference data point of the reference data and calibrating the sensor data using the matched data pair. 6. The system of claim 5, wherein the instructions configured to allow the processor module to calibrate the sensor data comprise instructions configured to cause the processor module to compensate for a time lag between the reference glucose data and the sensor data. 7. The system of claim 1, wherein the instructions configured to allow the processor module to calibrate the sensor data comprise instructions configured to cause the processor module to evaluate the sensor data to determine a sensor break-in and to request the reference glucose measurement responsive to the sensor break-in determination. 8. The system of claim 1, further comprising a hand-held computing device, wherein the sensor data receiver module, the reference data receiver module, the processor module and the computer readable medium are housed within the hand-held computing device. 9. A non-transitory computer-readable storage medium including code which when executed by at least one processor causes operations comprising: calibrating sensor data received from a substantially continuous glucose sensor;determining a rate of change of the calibrated sensor data;determining whether the rate of change is within a range of rates of change delimited by maximum normally sustainable rates of change of glucose in humans;receiving reference data generated from an in vitro glucose monitor; andcalibrating sensor data using the reference data generated from an in vitro glucose monitor only when the rate of change is within the range of rates of change delimited by maximum normally sustainable rates of change of glucose in humans. 10. The non-transitory computer-readable storage medium of claim 9, wherein the maximum normally sustainable rates of change of glucose in humans is within a range of about +/−4 mg/dL/min. 11. The non-transitory computer-readable storage medium of claim 9, wherein calibrating the sensor data using the time-corresponding reference data comprises forming a matched data pair by matching a sensor data point of the sensor data with a time-corresponding reference data point and calibrating the sensor data using the matched data pair. 12. The non-transitory computer-readable storage medium of claim 9, wherein calibrating the sensor data using the time-corresponding reference data further comprises compensating for a time lag between the reference glucose data and the sensor data.
