Both testing methods have several advantages and disadvantages inherent to them. Starting with the benefits, PCR testing allows large replication of genes in a relatively short period of time compared to the previous method of culturing. This facilitates researchers' ability to sequence, detect, and analyze fewer common organisms in the sample. PCR also sets up for other testing methods, such as the nucleic acid lateral flow assay, making itself useful in many circumstances. Lastly, the different variations of PCR allow researchers to analyze different forms of samples in several different ways. For example, RT-PCR allows the analysis of RNA samples instead of DNA samples, while qPCR allows scientists to quantify the targeted gene of the sample.
