A system for diagnostic testing may include a meter (130) for performing a diagnostic test on a sample applied to a test media (120) and a container (110) configured to contain test media compatible with the meter. The meter may include a closure portion (140) for selectively closing the opening of the container. The system may further provide a sampling device (360), such as a lancet, operable connected to the container. The system may also provide mechanisms to disable a power source, an auto-on function of the meter, a diagnostic testing function of the meter, or other function of the meter when it has been determined that a triggering event has occurred. The triggering event may be, e.g., the expiration of a certain expiration of a certain time period, passage of a certain date, performance of a certain quantity of diagnostic tests, or use of a certain quantity of test media.
