1 . A health monitoring device, comprising:
 a housing;   an analyte sensor operatively coupled to the housing, the analyte sensor monitoring an analyte level; and   a data transfer module coupled to the housing and in signal communication with the analyte sensor, the data transfer module receiving one or more signals related to a monitored analyte level and transmitting data related to the monitored analyte level in response to a request for the data, the data transfer module including a memory for storing the data related to the monitored analyte level.   
     
     
         2 . The device of  claim 1  wherein the data transfer module transmits the stored data related to the monitored analyte level only upon receiving the request. 
     
     
         3 . The device of  claim 1  wherein upon request the data transfer module transmits the data stored in the memory related to the monitored analyte level, or data related to a substantially real time analyte level, or both the data stored in the memory related to the monitored analyte level and the data related to the substantially real time analyte level. 
     
     
         4 . The device of  claim 1  wherein the analyte sensor is a glucose sensor. 
     
     
         5 . The device of  claim 1  wherein the data transfer module transmits a unique identifier with the transmitted data related to the monitored analyte level. 
     
     
         6 . The device of  claim 5  wherein the data transfer module is synchronized with an external device based at least in part on the transmitted unique identifier. 
     
     
         7 . The device of  claim 1  wherein the data related to the monitored analyte level is transmitted based on one or more of a wireless communication protocol or a wired connection. 
     
     
         8 . The device of  claim 7  wherein the wireless communication protocol includes a radio frequency (RF) communication protocol, optical communication protocol, Bluetooth communication protocol, or Zigbee communication protocol. 
     
     
         9 . The device of  claim 7  wherein the wired connection includes a universal serial bus (USB) connection or a cable connection. 
     
     
         10 . The device of  claim 1  wherein the memory of the data transfer module buffers the data related to the monitored analyte level. 
     
     
         11 . The device of  claim 10  wherein the data transfer module includes a processing unit configured to transmit the buffered data related to the monitored analyte level only on request. 
     
     
         12 . The device of  claim 1  wherein the data transfer module operates in one or more of a first data transmission mode, a second data transmission mode, or a third data transmission mode. 
     
     
         13 . The device of  claim 12  wherein the first data transmission mode includes transmitting the data related to the monitored analyte level in response to the request when a new sensor data is available. 
     
     
         14 . The device of  claim 12  wherein the second data transmission mode includes transmitting the data related to the monitored analyte level in response to the request when a new sensor data is available and storing the data related to the monitored analyte level for retransmission. 
     
     
         15 . The device of  claim 12  wherein the third transmission mode includes storing data related to the monitored analyte level and transmitting the stored data related to the monitored analyte level in response to the request. 
     
     
         16 . The device of  claim 1  wherein the data transfer module performs one or more of a prospective analysis or a retrospective analysis on the monitored analyte level. 
     
     
         17 . The device of  claim 1  wherein the analyte sensor requires no system calibration. 
     
     
         18 . The device of  claim 1  wherein the analyte sensor requires no user calibration. 
     
     
         19 . The device of  claim 1  wherein the analyte sensor is automatically calibrated.
