1. A glucose monitoring system comprising:
a glucose sensor, a portion of which is configured to be positioned under skin of the user, wherein the glucose sensor comprises at least two electrodes, and wherein the glucose sensor is configured to sample a biological fluid of the user to provide sensor data;
a transmitter unit coupled to the glucose sensor, the transmitter unit comprising a power supply, a processor of the transmitter unit, memory of the transmitter unit, and a radio frequency transceiver of the transmitter unit, wherein the transmitter unit is configured to:
receive the sensor data from the glucose sensor,
process the sensor data using calibration data to provide processed sensor data, wherein the calibration data comprises data associated with a sensitivity of the glucose sensor, and wherein the processed sensor data is stored in the memory of the transmitter unit, and
transmit the processed sensor data over a Bluetooth wireless communication link using the radio frequency transceiver of the transmitter unit; and
a primary receiver unit comprising a processor of the primary receiver unit, memory of the primary receiver unit, a radio frequency transceiver of the primary receiver unit, an antenna, and a display, wherein the primary receiver unit is configured to:
receive, using the antenna and the radio frequency transceiver of the primary receiver unit, the processed sensor data over the Bluetooth wireless communication link,
output to the display of the primary receiver unit, a numerical value based on the processed sensor data, and
output to the display of the primary receiver unit, a first line graph that is a continuous depiction of the processed sensor data over time,
wherein the transmitter unit and at least a portion of the glucose sensor are disposed within a single integrated housing,
wherein the glucose monitoring system is configured to detect an adverse condition, wherein the adverse condition comprises a signal error associated with the transmitter unit, wherein the adverse condition results in the primary receiver unit displaying a data gap such that the first line graph displayed on the primary receiver unit has an end corresponding to a time associated with a start of the adverse condition,
wherein, during a time period corresponding to the adverse condition, processed sensor data is stored in the memory of the transmitter unit,
wherein the primary receiver unit is configured to output to the display, after the adverse condition is corrected, processed sensor data for the time period corresponding to the adverse condition such that the data gap is backfilled, and
wherein the processed sensor data for the time period corresponding to the adverse condition that is outputted to the display after the adverse condition is corrected comprises a second line graph having a first end corresponding to the time associated with the start of the adverse condition and a second end corresponding to a time associated with an end of the adverse condition.
