ZURICH (AFP) – Swiss pharmaceutical giant Roche said yesterday it had developed an antibody test that it hopes to roll out in May to detect people previously infected with COVID-19, even those who displayed no symptoms.
Roche said in a statement that it had developed the Elecsys Anti-SARS-CoV-2 immunoassay, which using a blood sample can detect antibodies to determine the body’s immune reaction to the novel coronavirus that causes COVID-19.
Research teams around the world have been racing to develop such so-called serology tests for the virus, known as SARS-CoV-2, that has sparked the global pandemic with more than 2.1 million infections and over 141,000 deaths.
“Antibody testing is central to help identify people who have been infected by the virus, especially those who may have been infected but did not display symptoms,” the Roche statement pointed out.
It added that such tests could also allow screening within high risk groups like healthcare workers to determine if they may already have developed a certain level of immunity, Roche said.
“Once we understand more about the immunity against COVID-19, it could also help society return faster to normality,” it said.
