1. An integrated lancet and electrode structure, comprising:

  • a housing, comprising an extruded electrode structure, the extruded electrode structure comprising;

    a first extruded body comprising a first conductive material coextruded with a first dielectric material, wherein the first extruded body comprises a first channel;

    a second extruded body comprising a second conductive material coextruded with a second dielectric material, wherein the second extruded body comprises a second channel,wherein the first extruded body and the second extruded body are engaged to provide the extruded electrode structure,wherein the first conductive material is separated from the second conductive material by a space between the first extruded body and the second extruded body, wherein the space provides a reaction chamber, andwherein the first and second channels together define a lumen having a first opening and a second opening, wherein the lumen is adjacent to and in fluid communication with the reaction chamber, and wherein the lumen does not include the first and second conductive materials; and

    a lancet slidably positioned within the lumen, such that the lancet is capable of being extended through the lumen to expose the lancet and retracted to a position within the lumen such that the lancet is not exposed.
