1. An apparatus for determining the concentration of a medically significant component of a biological fluid, the apparatus comprising:

  • a cell for receiving a sample of the fluid, the cell supporting;

    a chemistry which reacts with the medically significant component; and

    first and second terminals across which the reaction of the chemistry with the medically significant component can be assessed;

    an instrument having;

    first and second terminals complementary to the first and second terminals, respectively, of the cell;

    wherein placement of the first and second terminals of the cell in contact with the first and second terminals, respectively, of the instrument permits the instrument to assess the reaction; and

    an assessment controller for;

    applying across the first and second terminals of the instrument a first signal;

    determining a first correction value in response of the cell to the first signal;

    assessing the reaction of the medically significant component with the chemistry; and

    combining the correction value with the result of the reaction assessment to produce an indication of the concentration of the medically significant component of the sample.
