Sample: Nasal and Throat Swabs
Principle: The test detects the virus’s RNA, which will be present in the body before antibodies form or symptoms of the disease are present, and tells whether or not someone has the infection. The test proceeds by converting the RNA to DNA through a process called ‘reverse transcription’.
TIME: The real time RT-PCR technique can deliver a reliable diagnosis in as little as three hours, although laboratories take on average between six and eight hours.
