1. A measuring device for analyzing a sample liquid for presence or concentration of at least one analyte, comprising:

  • a measuring device body having an open position and a closed position;

    evaluation electronics;

    a test field support housed in the measuring device and coupled to the evaluation electronics, the test field support including a plurality of test fields, each test field of the plurality being accessible to a user when the measuring device body is in the open position;

    each one of the plurality of test fields comprising an electrochemical measuring cell having a pair of sample sufficiency electrodes and a reagent adapted to react with a sample liquid to produce a response that is measurable by the evaluation electronics;

    wherein the evaluation electronics are adapted to determine which one of the plurality of test fields has been wetted with the body fluid sample; and

    wherein the device selectively provides visual indicia indicating which test fields of the plurality of test fields have been used and which remain unused.
