Abstract: A test unit collects and analyzes biological specimens on-site. It has one or more openings that allow reagent capsules to be inserted and guided into a testing chamber. Reagent capsules are pre-loaded with chemicals for screening and are configured as blister packs. A button mechanism allows projection(s) to open the blister packs to allow chemicals within the capsules to mix inside the testing chamber. A medical swab is affixed to a pop top dispenser cap and can be pressed to allow the swab to be inserted into the mixed chemicals. A visible test strip mount attached to the testing chamber has a lever to manipulate a test strip in and out of the testing chamber. This test strip may be slid through a uni-directional seal on a capsule and into a chemical for testing. The test strip will test for the presence of an infectious disease.
