Despite the symptoms of the corona, how come the test report is negative so how do know? Know the opinion of experts

New Delhi: Amidst increasing cases of coronavirus, India's top experts said on Monday that RT-PCR examination could detect coronavirus infection in about 80 percent of cases, so reports of symptomatic patients did not confirm the infection. If this happens, their CT scan or chest x-ray should be done and they should be checked again after 24 hours.

Amid the outbreak of new forms of SARS COV-2, experts said that the mutated variants of the virus could not be saved by RT-PCR screening, as the investigations in India can detect more than two genes.

A total of 1,189 samples were found infected with different forms of SARS COV-2 in India according to the government's data as of 15 April, of which 1,109 were found to be infected with the coronavirus pattern found in the UK, 79 in South Africa. And one specimen was found to be infected with the type of virus found in Brazil.

According to ICMR data, current RT-PCR investigations also reveal the current formats. The RT-PCR test gives correct results in 80 cases, but in 20 percent of the cases, the results may not be accurate.

Dr. Randeep Guleria, director of AIIMS, said, "If the sample is not taken properly or the test is done before the infection is not spread much further, the report will not confirm the infection. So if a person has signs of infection, treatment should be started according to the lab report, CT / Chest X-ray to detect Covid-19. Should be checked again after 24 hours. "

Dr. Sameeran Panda, head of the Department of Epidemiology and Communicable Diseases at the Indian Council of Medical Research (ICMR), said that the RT-PCR test detected the nature of the virus found in Britain, Brazil, and South Africa. However, in some cases, the infection is not detected.

Another senior doctor said that instead of relying only on the results of RT-PCR tests, treatment should be done based on symptoms and reports of CT scans.
