Amplification-based detection of pathogen nucleic acids hinges on making many copies of a specific genetic target so a tiny amount becomes detectable quickly. PCR does this by cycling through heating and cooling steps that separate the DNA strands, let primers bind to the target sequence, and have a DNA polymerase extend new strands, doubling the target each cycle. After just a few cycles, even trace amounts of pathogen DNA or RNA (with a reverse transcription step for RNA) produce a measurable product, enabling rapid identification. Real-time PCR can provide immediate readouts and, if needed, quantify how much pathogen is present, making the approach both fast and sensitive. Other options focus on detecting proteins rather than nucleic acids, or use different amplification formats that aren’t the standard rapid nucleic acid detection method, which is why PCR is the best choice in this context.
