1. An infusion system for infusing a fluid into a body of a user, the infusion system comprising:

  • a sensing device including;

    a sensor adapted to determine a concentration of a first analyte in the user;

    a sensing device processor coupled to the sensor and adapted to process the determined concentration of the first analyte in the user; and

    a sensing device transmitter coupled to the sensing device processor and adapted to transmit a communication including sensor values indicative of the determined concentration of the first analyte in the user;

    a characteristic determining device including;

    a determining device housing adapted to be carried by the user;

    a receptacle coupled to the determining device housing and adapted to receive and test a second analyte from the user to determine a concentration of the second analyte in the user;

    a determining device processor contained in the determining device housing and coupled to the receptacle and adapted to process the determined concentration of the second analyte from the receptacle; and

    a determining device transmitter contained in the determining device housing and coupled to the determining device processor and adapted to transmit a communication including the determined concentration of the second analyte in the user; and

    an infusion device including;

    an infusion device housing adapted to be carried by a user;

    a drive mechanism contained in the infusion device housing and operatively coupled with a reservoir containing a fluid for infusing the fluid into the body of the user;

    an infusion device receiver contained in the infusion device housing and adapted to receive the communications from the sensing device transmitter and the determining device transmitter;

    an infusion device processor contained in the infusion device housing and coupled to the infusion device receiver and adapted to process the sensor values received from the sensing device transmitter and the concentration of the second analyte in the user received from the determining device transmitter; and

    an infusion device indicator coupled to the infusion device processor and adapted to indicate the sensor values and the concentration of the second analyte in the user.
