Current antibody testing is not yet completely accurate, and many tests cannot quantitate antibody levels or types.   First, antibody-positive patients may have only low levels of viral neutralizing antibodies.  Then too, viral immunity requires activated T-lymphocyte killer cells to destroy virus and virus-infected cells.  Currently there are no tests that show if you have CoVid immune T lymphocytes.   So if you are tested and find that you do have antibodies, don’t get a false sense of security.  It could be deadly!   https://www.who.int/news-room/commentaries/detail/immunity-passports-in-the-context-of-covid-19   #covid19 #coronavirus #who #immunity #antibodies #cellmediatedimmunity #who
