A method of forming a plurality of electrodes on a test sensor includes providing a substrate. The test sensor assists in determining an analyte concentration. At least one aperture is formed through the substrate. Catalytic ink or catalytic polymeric solution is applied in a pattern on two sides of the substrate. The catalytic ink or catalytic polymeric solution assists in defining the plurality of electrodes on the test sensor. After applying the catalytic ink or catalytic polymeric solution, the substrate is electrolessly plated to form the plurality of the electrodes of the substrate. The plurality of electrodes assists in determining the concentration of the analyte.
