A total of 20,000 tests will be conducted across all the districts of Delhi, spanning all sections and ages, according to the official order.

The deputy commissioners of the districts will effectively coordinate with survey field teams, the order said.

This will enable authorities to undertake a comprehensive analysis of COVID-19 in the city and then a broad strategy can be prepared to combat the pandemic in the national capital, a ministry statement had said.

Serology (antibody) tests are largely used for surveillance among the community. They can be used on people who have already been tested positive for the virus or even those who are asymptomatic, and can reveal insights on immunity against coronavirus.

Delhi has 77,240 infections so far and 2,492 people have died due to the virus.
