Architecture for field upgrade of a health monitoring system

A system for managing healthcare data for a user, comprising:

• a first module circuit providing a first function, the first module circuit being a blood glucose meter configured to generate one or more measurements of a blood glucose concentration of the user, the blood glucose meter including:
• a sensor-receiving module disposed within a housing configured to receive a test sensor therein;
• a reaction-detection system disposed within the housing, the reaction-detection system being configured to be coupled with the test sensor received within the housing to detect a reaction caused by a blood sample being received by the test sensor;
• and
• at least one processor that executes program instructions to determine a glucose concentration of the blood sample based at least in part on the detected reaction;
• a second module circuit providing a second function, the second module circuit being a global positioning system (GPS) unit configured to generate GPS data associated with each of the one or more measurements;
• and
• a central circuit controlling the first module circuit and the second module circuit, the central circuit being configured allow the first module circuit to communicate with the second module circuit.
