Doctors should be aware most serology tests haven& #39;t been reviewed by FDA. Quality is highly variable, with some or perhaps many giving uncertain results. False positive rates may be inappropriately high. Patients and doctors shouldn& #39;t rely on unproven tests for clinical decisions

Depending on specificity of serology test being used, false positive rates can range from 25-50%; meaning tests that return positive result saying you have antibodies to covid may be wrong as much as half the time. Many tests have 95% specificity which leaves false positives high
