The ELISA IgG shoudl be used in survey having high-risk or vulnerable populations like healthcare workers, frontline workers, individuals in containment zones, for the knowledge about who have been infected in the past and got recovered now.
Details of seven pharma companies have been provided by the ICMR to undertake the production of indigenous COVID Kavach ELISA IgG kits which will help in antibody detection for COVID-19.
