Reliance Life Sciences has developed an RT-PCR kit that promises to ensure diagnosis of Covid-19 infection in about 2 hours, company sources said. The Covid-19 RT-PCR test, which is a real-time reverse transcription-polymerase chain reaction (rRT-PCR) test for the qualitative detection of nucleic acid from SARS-CoV-2, takes up to 24 hours to give a diagnosis or the test result. The computational biologists at Reliance Life Sciences, a subsidiary of Reliance Industries Ltd, analysed more than 100 genomes of SARS-CoV-2 sequenced in India and designed an unique RT-PCR primers for developing quantitative-Real Time PCR (RT-PCR) kit for Covid-19 detection. RT-PCR kit is so far considered as premium standard.
