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