1. An integrated monitor and display unit, comprising:

  • a housing;

    a data receiver disposed in the housing and configured to receive data relating to analyte signals generated by a transcutaneously positioned analyte sensor in fluid contact with interstitial fluid;

    a port coupled to the housing and configured to receive an in vitro analyte sensor, the in vitro analyte sensor having a conductive material on an exterior or interior surface; and

    a processor disposed in the housing and configured to validate the data relating to monitored analyte signals received from the transcutaneously positioned analyte sensor based at least in part on one or more signals from the in vitro analyte sensor, and further, to determine a type of in vitro analyte sensor when a presence of the in vitro analyte sensor in the port is detected;

    wherein the port is configured to receive a first type of in vitro analyte sensor which is not associated with one or more predetermined calibration parameters, and a second type of in vitro analyte sensor which is associated with the one or more predetermined calibration parameters; and

    wherein 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 a storage unit operatively coupled to the processor, the one or more predetermined calibration parameters associated with the in vitro analyte sensor when the determined type of the in vitro analyte sensor is of the second type.
