Abstract: The disclosure is directed to a test media reader module including a housing, a membrane, and an optical imager. The housing is configured to receive a test media adapter and has a barrier wall configured to separate the test media adapter from an interior of the housing. The barrier wall includes a window having an interior side and an exterior side. The membrane is transparent to a wavelength useful for imaging test media in the test media adapter. The membrane has a reactive region and overlies at least a portion of the exterior side of the window. The optical imager is located interior to the housing and is configured to image the test media located on the exterior side of the window along an optical path extending through the window and the membrane.

Abstract: The present disclosure is directed, in general, to an optical reading system, a universal testing cartridge, and a method of coupling optical reading systems. In a particular illustrative embodiment, the optical reading system includes a universal test cartridge receptor, test format determination logic, test criteria determination logic, and an optical reader module. The universal test cartridge receptor is responsive to a universal test cartridge having a test strip inserted therein. The test format determination logic determines an optical test format of the test strip. The test criteria determination logic determines an optical test criteria based upon the optical test format. The optical reader module is configured to capture an optical test image of the test strip.
