“Since the beginning of the pandemic, hundreds of serological tests have been developed, including more than 80 tests that received U.S. Food and Drug Administration Emergency Use Authorization. These tests represent different formats and have different viral antigen targets. The tests also detect different antibody isotypes and report qualitative or semi-quantitative or quantitative test results. Hundreds of studies have been published using multiple antibody assays, however, it is challenging to compare results or aggregate data since the assays were not calibrated to an international standard.
To address this challenge, the World Health Organization (WHO) generated an International Standard for SARS-CoV-2 antibodies. This webinar will provide attendees with an overview of how this standard was developed, how it supports serological assay development, and its role in the pandemic. The calibration of serological assays to a common unitage will improve our understanding of the virus epidemiology, and vaccine and therapeutic efficacies.”
