Described and illustrated herein is an exemplary method of operating an analyte measurement device having a display, user interface, processor, memory, and user interface buttons. Such method can be achieved by measuring an analyte with the analyte measurement device, displaying a value representative of the analyte, querying a user to select a predetermined flag to associate the predetermined flag with the value, and pressing only one of the user interface buttons once to store the predetermined flag with the value in the memory of the analyte measurement device. In one embodiment, the testing device is a glucose meter and the analyte being tested is glucose.
