The rapid diagnosis of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection relies on the availability of a robust method. The demand for SARS-CoV-2 diagnostic kits and other desirable consumables for timely diagnosis have increased drastically after the current pandemic. The cumulative efforts by scientists, funding agencies, regulatory authorities, and corporates have accelerated the process of kit development. Worldwide, rapid molecular techno progression to characterize the biology of any pathogen witnessed during this pandemic faster than ever. Moreover, a paradigm shift from real-time polymerase chain reaction technique to highly sensitive novel CRISPR technology has been observed. India, second most populous country actively leveraged molecular technologies for rapid diagnosis of SARS-CoV-2. This paper focuses on paradigm shift in the methods for diagnosis of SARS-CoV-2 infection with a focus on molecular innovations carried out in India indigenously.
