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.
