Explained: How TrueNat test works - The Indian Express

Jun 19, 2020·The SARS-CoV-2 virus, which causes Covid-19, does not have a DNA, but an RNA molecule. The reverse transcription process (the RT in RT-PCR) converts the RNA into the DNA molecule before the gene can be captured in the test. TrueNat is a chip-based, battery-operated RT-PCR kit. Initially, it could only identify the E-gene in the SARS-CoV-2 virus.
