1. An electrode reaction area testing method of biosensor test strip, comprising the steps of:

  • preparing a semi-finished or finished test strip product having a substrate and a separating plate, wherein the separating plate has a sensing window, the substrate has a first electrode, a second electrode and a third electrode disposed on a side of the sensing window and sequentially arranged from the outside to the inside;

    an end of the first electrode proximate to the sensing window is a first reacting electrode, an end of the second electrode proximate to the sensing window is a second reacting electrode, an end of the third electrode proximate to the sensing window is a third reacting electrode;

    covering the separating plate onto the first electrode, the second electrode and the third electrode;

    aligning the sensing window with the first reacting electrode, the second reacting electrode and the third reacting electrode, wherein each of the first reacting electrode, the second reacting electrode and the third reacting electrode has a partial area exposed from the sensing window;

    the partial area of the first reacting electrode exposed from the sensing window is a first electrode reaction area;

    the partial area of the second reacting electrode exposed from the sensing window is a second electrode reaction area;

    the partial area of the third reacting electrode exposed from the sensing window is a third electrode reaction area;

    introducing a sample into the test strip, and applying a voltage, such that the first electrode reaction area generates a first electrode reaction current, and the third electrode reaction area generates a third electrode reaction current;

    detecting and obtaining the first electrode reaction current and the third electrode reaction current, and then calculating a current ratio of the first electrode reaction current to the third electrode reaction current;

    determining whether the current ratio falls within a predetermined numeric value range;

    if yes, then the electrode reaction area of the semi-finished or finished test strip product is good and the separating plate attaching position or insulating position is correct, or else the electrode reaction area of the semi-finished or finished test strip product is defective and the separating plate attaching position or insulating position is incorrect; and

    completing the test of the electrode reaction area of the semi-finished or finished test strip product to determine whether the test strip is a good product or a defective product.
