How a pcr works
WebIn order for a virus like the COVID-19 virus to be detected early in the body using real time RT–PCR, scientists need to convert the RNA to DNA. This is a process called ‘reverse transcription’. They do this because only DNA can be copied — or amplified — which is a key part of the real time RT–PCR process for detecting viruses. Web27 de fev. de 2024 · However, a “PCR test” typically refers to a quick, accurate diagnostic test for the early signs of an infectious disease. For example, this is one way of testing …
