New Delhi. The central government on Wednesday said that by ‘lateral flow’ test, including rapid antigen test and antigen test done at home, COVID can be detected from the third day to the eighth day of being infected with the virus, while RT-PCR test can detect 20 Infection can be detected for days. Dr Balram Bhargava, Director General of the Indian Council of Medical Research (ICMR), said that no matter what kind of test is done, its result will be ‘negative’ on the first day of infection.
Bhargava said, ‘The virus takes time to grow in your body and this is called ‘Latent Period’. From the third day to the eighth day, it will be revealed in the lateral flow test, which is the ‘infectious period’. “That’s why the policy of release from the hospital and home quarantine focuses on a period of seven days,” he said. He said that the results of RT-PCR test come positive even after the eighth day because some RNA particles that do not infect, they confirm the infection in the test.
The Director General of ICMR said that the lateral flow has become the basis for investigation for the Omicron form of the virus.
Bhargava said that as per the government advisory, those who have come in contact with the infected, who have been identified on the basis of age or illness, people traveling inter-state need not get tested.
