24. An integrated lancet and electrode structure, comprising:
-
a housing, comprising an extruded electrode structure, comprising; a first extruded body comprising a first conductive material coextruded with a first dielectric material, wherein the first extruded body defines a first channel; a second extruded body comprising a second conductive material coextruded with a second dielectric material, wherein the second extruded body defines a second channel, wherein the first extruded body and the second extruded body are engaged to provide an electrode structure, wherein the first conductive material is electrically isolated from the second conductive material, and wherein the first and second channels together define a lumen having a first opening and a second opening; 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. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)

63. A method for determining a concentration of an analyte in a fluid sample from a subject, the method comprising:
-
lancing the subject using an integrated lancet and electrode structure to provide a fluid sample, the integrated lancet and electrode structure comprising; a housing, comprising an extruded electrode structure, comprising; a first extruded body comprising a first conductive material coextruded with a first dielectric material, wherein the first extruded body defines a first channel; a second extruded body comprising a second conductive material coextruded with a second dielectric material, wherein the second extruded body defines a second channel, wherein the first extruded body and the second extruded body are engaged to provide an electrode structure, wherein the first conductive material is electrically isolated from the second conductive material, and wherein the first and second channels together define a lumen having a first opening and a second opening; 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, and wherein the first conductive material comprises a working electrode and the second conductive material comprises a reference/counter electrode, the working electrode comprising an analyte responsive enzyme disposed on, in or proximate thereto; contacting the fluid sample with the electrode structure; generating a sensor signal at the working electrode; and determining the concentration of the analyte using the sensor signal. - View Dependent Claims (64, 65, 66, 67, 68, 69, 70, 71, 72)
