Investigative correspondent Drew Griffin. He's got details drew. What are you learning that? The confusion surrounding these antibody test is leading to a lot of problems with knowing what to do with the data. As far as we can tell Wolf there is no national plan to use that the antibody test a blood test that can tell whether someone has. Kovic nineteen even without symptoms has been so important.
