U of T Antibody Test Detects Past COVID-19 Infection and Quality of Immune Response

Posted on

A blood test designed by researchers at the University of Toronto and Sinai Health’s Lunenfeld-Tanenbaum Research Institute can accurately detect whether a person was previously infected with the virus that causes COVID-19 — and whether their immune response is functional.

The researchers found the test can detect the presence of antibodies to the SARS-CoV-2 virus and also evaluate whether these antibodies can block attachment of the viral spike protein to the human protein ACE2, a critical step in the infection process….
