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. WebThe PCR test looks for the genetic material of the virus in a swab sample taken from a person’s nose or throat. It involves making lots of copies of a piece of the virus’s genetic material so we can see if it is there or not. PCR is also one of the most important techniques that we use in our research at the Otago Department of Biochemistry.
