1. A test media reader module comprising:

  • a test media adapter configured to receive a test media that provides optical indication of a presence of a first analyte;

    a housing configured to couple to the test media adapter, the housing having a barrier configured to separate the test media adapter from an interior of the housing, the barrier including a window having an interior side and an exterior side;

    a membrane transparent to a wavelength useful for imaging a particular test media in the test media adapter, the membrane having at least one reactive region responsive to a proximate condition to change at least one optical characteristic of the at least one reactive region, the membrane overlying at least a portion of the exterior side of the window; and

    an optical imager located proximal to the interior side of the window, wherein the optical imager is operative to capture an image including the particular test media in the test media adapter and the at least one reactive region of the membrane along an optical path extending through the window and the membrane.
