Centre asks states to step up antigen tests

NEWDELHI: Centre moved to make access to Covid-19 testing easier for people on Wednesday, asking states to involve private laboratories up to their full capacity, and also allow both government and private doctors to prescribe Covid-19 testing, including antigen based testing, for diagnosis.

Union health secretary, Preeti Sudan, and secretary, department of health research, Dr Balram Bhargava, jointly wrote to all states to ramp up Covid-19 testing using rapid antigen based tests, to early detect cases for containing the pandemic.

An antigen is a foreign molecule that induces an immune response in the body, especially the production of antibodies, and its presence determines a present infection, which is why the ICMR recommended it for diagnosis along with RT-PCR test. The Centre asked states to start antigenbased testing in “campaign mode” by setting “camps/mobile vans” in high incidence areas.

“It is important to maintain strict vigil and continue to make all possible efforts to minimize the damage that can be caused by the pandemic. With the start of Unlock 2, focus will continue to be on saving lives and also protecting livelihood as more and more economic activities are expected to pick up gradually. Since testtrack-treat is the key strategy for early detection and containment of the pandemic, it is important to augment testing for Sars-Cov-2 in all parts of the country. This is the only way to detect the infection early and prevent its spread,” read the letter to states.

“…ICMR has also recommended use of a rapid point-ofcare antigen test kit for diagnosis, and more such kits are being validated to increase the available options to the citizens,” it added. HTC
