1. A method for manufacturing a test sensor for determining an analyte concentration in a liquid sample, the method comprising:

  • providing from a first roll a polymer carrier strip having a first surface;

    attaching a test membrane obtained from a second roll directly to the first surface of the carrier strip;

    impregnating the test membrane with a reagent after the test membrane is attached to the first surface of the carrier strip;

    providing a base having a second surface with a capillary channel and reaction area formed therein, the reaction area including a bottom and side walls; and

    adhering the first surface of the carrier strip directly to the second surface of the base over at least a portion of the reaction area such that the test membrane extends into the reaction area formed in second surface of the base without contacting the bottom and side walls of the reaction area.
