CDC Says Don’t Rely on Antibody Tests for Reopening Schools and Businesses The tests, also known as
serologic tests, have been
producing inconsistent
and inaccurate results. CDC, via guidance Since “overall prevalence of antibodies
in most populations is likely low,” the
tests could produce false positives
“less than half” of the time. The agency has warned those who have tested
positive for the antibodies not to assume that
they are protected from COVID-19. The CDC’s guidance follows an American
Medical Association report saying tests should
not be used in "determining immune status."
