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
The use of rapid antigen tests for diagnosis of SARS-CoV-2 infection is a key element of COVID-19 prevention and detection.
PCR tests are 99% accurate
Polymerase chain reaction also known as PCR is a laboratory technique for rapidly producing millions to billions of copies of a specific segment of DNA, which can then be used to detect DNA and RNA.
Chances are very rare that a PCR test can go wrong
