1. An instrument for determining concentration of glucose in a blood sample, comprising:

  • a display;

    first and second terminals for contacting complimentary first and second terminals of an electrochemical cell adapted to receive a blood sample;

    an assessment controller configured and arranged to;

    detect deposit of the sample in the cell;

    determine sufficiency of volume of the deposited sample;

    determine a correction value based on an electrical response from the cell;

    obtain an indicated glucose concentration by assessing a reaction of glucose in the blood sample with a chemistry provided in the cell;

    apply the correction value to the indicated glucose concentration to arrive at an actual glucose concentration, the actual glucose concentration comprising a compensated indication of the glucose concentration; and

    display the actual glucose concentration on the display no more than 10 seconds from the detection of deposit of the sample.
