Abstract
A specimen delivery cartridge includes a lower housing, and an upper housing. The upper housing is coupled to the lower housing at a hinge. The specimen delivery cartridge further comprises a testing chamber comprising a paper testing substrate. The paper testing substrate may include a wicking conduit and a plurality of test areas. The specimen delivery cartridge may also include a lens assembly proximate the plurality of test areas and operable to transmit light emissions from the plurality of test areas to an image sensor of a computing device. In some embodiments, the specimen delivery cartridge includes a testing substrate having a plurality of test areas made of an array of electrodes. Each electrode is printed on a first side of the testing substrate and coupled to a conductive via formed in the testing substrate and a conductive trace printed on a second, opposing side of the testing substrate.
