A system for diagnostic testing may include a meter for performing a test on a sample applied to a test media and a selectively closable container configured to house test media compatible with the meter. The system may also provide mechanisms for removing a meter from a test container and reattaching it to a new one using one of several coding methods that recalibrate the meter for the new container of test strips. Alternatively, the system may include an auto-calibration system where data is provided individually on each individual test medium in a form readable by the test meter. The carried data may include an embedded code relating to data particular to that individual strip. The data is presented so as to be read by a meter associated with the diagnostic test strip in order to avoid manually inputting the information. In addition, the system may further provide mechanisms to reconfigure the meter to perform a new function when it has been determined that a triggering event has occurred.
