1. A method of detecting a target nucleic acid using a stand-alone molecular diagnostic test device without any external instrument, comprising:

  • conveying an input sample from a sample preparation module to an amplification module, the sample preparation module and the amplification module each fixedly coupled within a housing of the stand-alone molecular diagnostic test device, the housing having an overall size of less than about 260 cubic centimeters, the amplification module defining a reaction volume and including a heater;

    heating the input sample within at least a portion of the reaction volume via the heater to amplify the target nucleic acid molecule within the input sample thereby producing an output solution containing a target amplicon; and

    reacting within a detection module within the housing each of A) the output solution and B) a reagent formulated to produce a signal that indicates a presence of the target amplicon within the output solution, the detection module including a detection surface configured to capture the target amplicon to produce the signal,the stand-alone molecular diagnostic test device producing the signal in less than about 25 minutes after the input sample is conveyed from the sample preparation module.
