1. An integrated monitor and display unit, comprising:

  • a housing, comprising;

    a radio frequency (RF) receiver disposed in the housing and configured to receive data relating to analyte signals generated by a transcutaneous analyte sensor from a transmitter;

    an analyte sensor port coupled to the housing and configured to receive an in vitro analyte sensor that includes a conductive material on an exterior or interior surface of the in vitro analyte sensor, wherein the in vitro analyte sensor generates an analyte signal from a fluid sample; and

    a processor disposed in the housing and configured to validate the data relating to the analyte signals from the transcutaneous analyte sensor based at least in part on the analyte signal from the in vitro analyte sensor, and to determine a type of in vitro analyte sensor upon detecting the presence of the in vitro analyte sensor in the analyte sensor port;

    wherein the processor is configured to transition from an inactive mode to an active mode upon detection of an electrical circuit being closed upon receipt of the in vitro analyte sensor in the analyte sensor port,wherein the analyte sensor port is configured to receive a first type of in vitro analyte sensor which is not associated with one or more predetermined calibration parameters stored in a storage unit operatively coupled to the processor, and a second type of in vitro analyte sensor which is associated with the one or more predetermined calibration parameters, andwherein the processor is configured to generate a request to provide a calibration parameter associated with the in vitro analyte sensor when the determined type of the in vitro analyte sensor is of the first type, or to retrieve from the storage unit one or more of the calibration parameters associated with the in vitro analyte sensor when the determined type of the in vitro analyte sensor is of the second type.
