Chennai: Tamilnadu’s Directorate of Public Health is all geared up for a serological survey. According to sources, it will be done in 888 clusters in all districts and around 60,000 samples will be collected.

The ICMR is conducting its own serosurveillance across the country in which samples from Tamilnadu are also tested. Considered the gold standard to measure recent or past exposure to infectious diseases, sero surveillance study is conducted to ascertain the antibody levels produced against the infection by testing blood (serum or plasma) samples.
