Mohibullah Salih*

The recent outbreaks of human corona virus infections, at the beginning of 21th century has shown the prominent roles of rapid and accurate diagnostic technologies, to contain the emerging and re-emerging pandemics. Despite the development of specific and sensitive point of care tests & serological immunoassays, RT-PCR still remain the gold standard performed on respiratory specimens for diagnosis of COVID-19. Even though excellent techniques are available for the diagnosis of symptomatic patients with COVID-19 in well- equipped laboratories; critical gap still remain in screening asymptomatic people who are in incubation phase of the disease, as well as in the accurate determination of live viral shedding during convalescence to make decisions for ending isolation.
