Sero survey is done by analysing blood samples of selected individuals for antibodies against Sars-Cov-2, the virus that causes Covid-19. It determines if a person has already been infected and recovered, considering a majority of patients do not exhibit symptoms and not everyone is getting tested for the viral infection.

The sero survey also aims to determine how the disease prevalence has changed since the first sero survey in May, when the nationwide lockdown was in force, to now, post-lockdown with fewer restrictions on public movement.

Like the previous survey, this survey was also designed as a cross-sectional survey of adults aged 18 years or above from 21 states, wherein the districts were categorised into four strata according to the reported Covid-19 cases per million population (zero, low: 0.1-4.7, medium: 4.8-10 and high: >10).
