1. A method of measuring an analyte concentration in body fluid in an animal body having skin and subcutaneous soft tissue that includes body fluid, said method comprising:

  • (a) providing an analyte measuring device, including;

    (i) an analyte sensing element, having a sharpened distal end to facilitate introduction into said animal body and further having an indicating electrode, said indicating electrode being adapted to be activated by electric power, and to form a raw analyte measurement when so activated and in contact with said body fluid, in less than two minutes;

    (ii) a reference electrode; and

    (iii) an electric power, data processing and display device adapted to mate to said analyte sensing element and activate said analyte sensing element by applying electric power to it and adapted to receive said raw analyte measurement and to compute and display a refined analyte measurement, related to said raw analyte measurement;

    (b) introducing said analyte sensing element into said animal body subcutaneous soft tissue, thereby placing said indicating electrode into contact with said animal body subcutaneous soft tissue and said body fluid;

    (c) activating said analyte sensing element by applying electric power to it, thereby causing said analyte sensing element to form a raw analyte measurement;

    (d) receiving said raw analyte measurement in said electric power, data processing and display device and computing and displaying a refined analyte measurement, related to said raw analyte measurement;

    (e) removing said indicating electrode from said body soft tissue, within two minutes of said introducing; and

    (f) timing steps (b), (c) and (e) so that said analyte sensing element is activated for at least part of the time it is, at least in part, dwelling in said subcutaneous soft tissue.
