A system is provided for monitoring analyte in a host, including a continuous analyte sensor that produces a data stream indicative of a host's analyte concentration and a device that receives and records data from the data stream from the continuous analyte sensor. In one embodiment, the device includes a single point analyte monitor, from which it obtains an analyte value, and is configured to display only single point analyte measurement values, and not any analyte measurement values associated with data received from the continuous analyte sensor. Instead, data received from the continuous analyte sensor is used to provide alarms to the user when the analyte concentration and/or the rate of change of analyte concentration, as measured by the continuous analyte sensor, is above or below a predetermined range. Data received from the continuous analyte sensor may also be used to prompt the diabetic or caregiver to take certain actions, such as to perform another single point blood glucose measurement. In another embodiment, the device provides for toggling between two modes, with one mode that allows for display of glucose concentration values associated with the continuous glucose sensor and a second mode that prevents the display of glucose concentration values associated with the continuous glucose sensor.

1. A method for monitoring a glucose concentration of a host using a continuous glucose sensor, comprising: generating, using a continuous glucose sensor, a data stream indicative of a host's glucose concentration during a first time period and a second time period;processing the data stream to determine a real-time glucose concentration value of the host;recording, using a mobile computing device, the data stream and/or information derived from or associated with the data stream;triggering, using the mobile computing device, a real-time hypoglycemia event alarm, wherein the determining of when to trigger the alarm is based at least in part on comparing the determined real-time glucose concentration to a predetermined hypoglycemia threshold;initiating, using the mobile computing device, a first mode wherein display of the real-time glucose concentration values based on the data stream is disabled by the computing device but triggering the hypoglycemia event alarm is enabled by the mobile computing device;initiating a second mode, using the mobile computing device, wherein both display of glucose concentration values based on the data stream and triggering the hypoglycemia event alarm are enabled by the mobile computing device; andgenerating and displaying on a computer display a performance report that user-perceptively distinguishes glucose concentration values associated with the data stream generated during the first time period from glucose concentration values associated with the data stream generated during the second time period, wherein the first time period is when the mobile computing device is in the first mode and wherein the second time period when the mobile computing device is in the second mode. 2. The method of claim 1, further comprising transferring data from a single point glucose monitor to the computing device. 3. The method of claim 1, further comprising performing retrospective analysis on the data stream using the computing device. 4. A method for monitoring a glucose concentration in a user using a mobile computing device, the method comprising: receiving, from a continuous glucose sensor, a data stream indicative of a host's glucose concentration;processing the data stream;recording the data stream without displaying any information associated with the data stream on the computing device while in a blinded mode;recording the data stream without displaying any information associated with the data stream on the computing device while in an unblinded mode;triggering a user-perceptible hypoglycemia event alarm on the computing device based at least in part on a comparison of information associated with the processed data stream with a predetermined hypoglycemia threshold;calculating a change in glucose concentration values from a first time period and a second time period, wherein the first time period of the two time periods is a time period when the computing device is in the blinded mode and wherein the second time period of two time periods is a time period when the computing device is in the unblinded mode; andgenerating and displaying a performance report that includes a representation of a result of the calculation so to provide to a user an indication of a difference in glucose values while in the blinded mode from the unblinded mode. 5. The method of claim 4, further comprising prompting a user to enter calibration information using the computing device and accepting user input indicative of calibration information. 6. The method of claim 5, wherein the calibration information is a single point glucose measurement. 7. The method of claim 4, further comprising transmitting the data stream or data derived from the data stream over a communication link to a computer network. 8. A system for monitoring a glucose concentration of a host measured b a continuous glucose sensor, the system comprising: one or more processors;non-transitory computer-readable instructions that, when executed by the one or more processors, cause the system to: receive, from a continuous glucose sensor, a data stream indicative of a host's glucose concentration;process the data stream to determine a real-time glucose concentration values of the host;record the data stream and/or information derived from or associated with the data stream in computer memory;trigger a hypoglycemia event alarm, wherein the determining of when to trigger the alarm is based at least in part on a comparison of the determined real-time glucose concentration with a predetermined hypoglycemia threshold;initiate a first mode that prevents the device from displaying on a display screen of the device real-time glucose concentration values based on the data stream but allows triggering the hypoglycemia event alarm;initiate a second mode that allows the device to display real-time glucose concentration values on the display screen of the device based on the data stream and allows triggering the hypoglycemia event alarm;identify one or more changes in information derived from the data stream from a first predefined time period to a second, different predefined time period, wherein the first time period is a time period when the device is in the blinded mode and wherein the second time period is a time period when the device is in the unblinded mode;generate a performance report that includes a representation of a result of the identifying; anddisplay on a computer display the performance report. 9. The device of claim 8, wherein the non-transitory computer-readable instructions, when executed by the one or more processors, are further configured to cause the device to perform retrospective analysis on the data stream using the computing device. 10.
