Abstract: A testing system (10) for an infectious disease, such as Covod-19, has a specimen collector (11) with a housing (12) receiving a specimen of bodily fluids discharged from a cough of a test subject through a specimen inlet (15). After specimen collection, the specimen inlet (15) is closed, and the collector (11) is brough to a mating electronic testing device (13). A seal (55) is removed to expose a transparent specimen tray (43) upon which the specimen has fallen and installed into a collector receptacle (14). A microscope (15) is focused on the specimen, Photographs of the specimen are taken through a microscope (15) and then compared to photographs of specimens known to have indications of infection (26). Based on the comparison, a test result and level of confidence is obtained. The collector (11) is then removed from the testing device (13), and discarded.
