A portable insulin injection pen and blood glucose monitoring device is integrated into a single unit for testing and treating diabetes symptoms. The device has a housing of a size suitable for transport in a user s clothing pocket or handbag. Within the housing is a blood glucose monitoring system for receiving a sample of the user s blood and detecting its glucose level an insulin injection mechanism for administering an insulin injection and a microprocessor that calculates an insulin dosage appropriate to the detected blood glucose level and sets the insulin injection mechanism to administer the calculated insulin dosage. A communication device automatically informs a remote emergency service provider such as 911 or an emergency service to which the user has subscribed if the microprocessor determines that the detected blood glucose level presents a potential danger to the user. The microprocessor also calculates treatment regimens specific to a particular user based on the detected blood glucose level and displays the treatment regimens on an LCD display. In a particularly advantageous embodiment a GPS receiver within the housing detects the location of the device and the communication device which can be a cellular telephone separate from the housing connected wirelessly to the unit via a Bluetooth connection or cellular telephone circuitry within the housing itself transmits information regarding the location to the remote emergency service.
