1. A computer system suitable for processing analyte data, the computer system comprising:
- a sensor data module configured to receive sensor data, the sensor data comprising a data stream comprising a plurality of time spaced sensor data points from a substantially continuous analyte sensor;
a processor module configured to determine a rate of change of the data stream; and
a reference input module configured to receive reference data from a reference analyte monitor, the reference data comprising at least one reference data point.

14. A device for monitoring glucose concentration in a biological sample of a host, the device comprising:
-
a substantially continuous glucose sensor that produces a data stream indicative of a glucose concentration in a host, the data stream comprising a plurality of time spaced sensor data points;
an integrated receiver that receives the data stream from the substantially continuous glucose sensor, wherein the integrated receiver comprises;
a single point glucose monitor configured to receive a biological sample from the host and to measure the concentration of glucose in the sample, the measured glucose concentration comprising a reference data point;
a microprocessor; and
a computer readable memory comprising;
instructions configured to cause the microprocessor to process the data stream received from the continuous glucose sensor;
instructions configured to cause the microprocessor to determine a rate of change of the data stream from the substantially continuous analyte sensor; and
instructions configured to cause the microprocessor to calibrate the data stream using the glucose concentration measured by the single point glucose monitor. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
