The Covid RT-PCR test is a definitive and gold standard test procedure for determining the Covid19 infection. It provides a rapid means of assessment for viral load in the body and is, therefore, a reliable tool to diagnose Covid 19 infection at a very early stage. Asymptomatic individuals, who may be just carriers of the virus, are an important source of spread in the community.
Covid RT-PCR test enables us to contain the spread of Covid-19 infection by identifying such carrier individuals who may have mild symptoms or are completely asymptomatic.
The other diagnostic test for Covid 19 is an antigen test. This test requires a minimum amount of virus to be present in the bloodstream for it to reflect a positive test result; whereas, the Covid RT-PCR test can determine the presence of the virus before it spreads in the body as it does not require a specific viral load.
An antigen test may show false-positive or false-negative results too. Therefore, the Covid RT-PCR test is more sensitive, more accurate, and more reliable for medical professionals to detect the infection of the virus.
