ICMR Asks States To Conduct IgG Antibody Test

ICMR advises States to conduct sero-survey to measure Coronavirus exposure in the population using IgG ELISA Test.

IgG antibodies generally start appearing after two weeks of onset of infection, once the individual has recovered after infection and last for several months. Therefore, the IgG test is not useful for detecting acute infection but indicates episode of SARS-CoV-2 infection in the past.

The sero-survey would be conducted using an IgG ELISA kit. Scientists at ICMR-National Institute of Virology, Pune have developed and validated an indigenous IgG ELISA test for antibody detection for SARS-CoV-2. To fast track production and increase availability of the IgG ELISA test, ICMR has transferred this technology to many pharma companies viz. Zydus Cadila, J Mitra & Company, Meril Diagnostics, Voxtur Bio, Trivitron Healthcare, Karwah Enterprises, Avecon Healthcare, etc. The technology has been transferred to various entities without exclusivity clause and therefore can be further shared with others as per demand and capability.
