1. An apparatus including an integrated monitor and display unit, comprising:

  • a housing, comprising;

    a radio frequency (RF) receiver disposed in the housing to receive data from a transmitter that is configured and arranged to transmit data relating to analyte levels from a transcutaneous analyte sensor;

    an analyte sensor port coupled with the housing and configured to receive an in vitro analyte sensor, wherein the in vitro analyte sensor generates an analyte signal from a fluid sample;

    a memory configured to store a universal calibration parameter associated with all in vitro analyte sensors that are no-coding in vitro analyte sensors, wherein the universal calibration parameter is stored in the memory prior to receipt of the in vitro analyte sensor in the analyte sensor port; and

    a processor disposed in the housing and operatively coupled to the RF receiver and the memory, the processor configured to validate the data relating to analyte levels from the transcutaneous analyte sensor based at least in part on the analyte signal generated by the in vitro analyte sensor, to recognize the in vitro analyte sensor without a user inputting information when the in vitro analyte sensor is received in the analyte sensor port and is a no-coding in vitro analyte sensor, and to retrieve the universal calibration parameter stored in the memory when the recognized in vitro analyte sensor is the no-coding in vitro analyte sensor.
