1. An electrochemical test strip powered by a power source comprising:

  • a contact zone adapted to be contacted by the power source;

    a first measurement electrode;

    a first conductive trace operatively coupled to the first measurement electrode and to the contact zone, wherein the distance between at least one point on the first conductive trace and the contact zone is greater than or equal to the distance between any point on said first measurement electrode and the contact zone;

    a second conductive trace operatively coupled to the first measurement electrode and to the contact zone;

    a second measurement electrode;

    a third conductive trace operatively coupled to the second measurement electrode;

    wherein the distance between at least one point on the third conductive trace and the contact zone is greater than or equal to the distance between any point on said second measurement electrode and the contact zone; and

    a fourth conductive trace operatively coupled to the second measurement electrode and to the contact zone.
