1. 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 signals 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; and
a processor disposed in the housing and configured to validate the data relating to analyte signals from the transcutaneous analyte sensor based at least in part on the analyte signal from the in vitro analyte sensor, to detect the presence of the in vitro analyte sensor when an electric circuit is closed by the insertion of the in vitro analyte sensor into the analyte sensor port, 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 analyte sensor port is configured to receive a first type of in vitro analyte sensor which is not associated with a predetermined calibration parameter and a second type of in vitro analyte sensor which is associated with the predetermined calibration parameter, 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 the calibration parameter associated with the in vitro analyte sensor when the determined type of the in vitro analyte sensor is of the second type.
