Development of RT-PCR Based Diagnosis of SARS-CoV-2

In the 2020, COVID-19 pandemic disease created an havoc situation world widely and mainly caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). It has been challenging task for researchers, scientists and medico-pharmaceutical organisations to find out rapid and reliable diagnosis methods. Among the all testing services, a Reverse Transcription Polymerase Chain Reaction (RT-PCR) is the more accurate, rapid and authenticated molecular technique used for most of the diagnosis of major diseases. It has been a global priority to fix the rapid diagnosis method to combat against the pandemic COVID-19. Thus, the present chapter mainly focussing on the progress of RT-PCR method development though various processes of data collection on isolation of whole genome sequence, its primer and method designing. In this scenario, India suddenly become the global leader for vaccine development and hence the challenges and RT-PCR kit development in India and rest of the world has been be discussed. World wide many Government and private agencies and industries have taken an initiative for diagnosis of SARS-CoV-2 hence this chapter also summarised the scope of RT-PCR to combat pandemic situation in future.
