Swiss pharmaceutical giant Roche said Friday 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.
