Abbott Rolling Out a Coronavirus Antibody Test
Abbott (NYSE: ABT) announced Wednesday it is launching a third test for SARS-CoV-2 -- and its first antibody test for the coronavirus.
Antibodies are blood proteins produced by the body in the latter stages of fighting an infection, and which bind to antigens -- molecules on the surface of alien substances, such as bacteria and viruses. Those antibodies can persist in the bloodstream for months or years following a person's recovery from an illness. Abbott's new product tests for the presence of a particular antibody, IgG, that is produced during a SARS-CoV-2 infection.
