1. A transdermal test sensor assembly adapted to determine an analyte concentration of a fluid sample, the test sensor assembly comprising:

  • a sensor support including at least one reservoir holding a liquid;

    a test sensor coupled to the sensor support, the test sensor forming at least one aperture therein, at least a portion of the at least one aperture being adjacent to the at least one reservoir; and

    a hydrogel composition positioned on the test sensor, the hydrogel composition being linked to the at least one reservoir via the at least one aperture,wherein the hydrogel composition includes a first percentage of a solvent, and the liquid of the at least one reservoir includes a second percentage of a solvent, the second solvent percentage of the liquid being greater than the first solvent percentage of the hydrogel.
