Abstract: Embodiments of the present disclosure generally pertain to systems and methods for performing amplicon rescue multiplex polymerase chain reaction (arm-PCR). In one embodiment, the system comprises a processor and a reader coupled to a control element. The control element is configured to control the operation of the processor and the reader based on a variety of settings. The processor is configured to receive a self-contained cassette for performing PCR amplification of DNA and/or RNA obtained from an organic specimen. The processor engages with the cassette and manipulates reagents within the cassette in order to amplify and detect the DNA from the specimen. The processor also causes the cassette to deposit the DNA on a microarray within the cassette. The reader is configured to receive the cassette after it has been processed by the processor and to capture an image of the microarray for transmission to the control element as test data.
