1. A method for operating a diabetes management system having an infusion pump, at least one glucose monitor and a microcontroller, the method comprising the following steps performed with the microcontroller:

  • determining a glucose measurement in which a fluid sample with glucose is transformed into enzymatic byproducts by application of electrical signals to the sample;

    calculating a bolus recommendation based on the glucose measurement made by the determining step;

    evaluating whether the bolus recommendation was followed by a user of the system;

    in the event the bolus recommendation was not followed by the user then;

    storing the actual bolus delivered by the infusion pump;

    measuring the glucose value in subsequent fluid samples and if the glucose values over time is greater than a predetermined high trend threshold then annunciating a high glucose trend, along with the recommended bolus and the actual bolus delivered by the pump otherwise if the glucose values over time is less than a predetermined low trend threshold then annunciating a low glucose trend along with both the recommended bolus and the actual bolus delivered by the pump.
