Clinical evaluation of 2 point-of-care lateral flow tests for the diagnosis of syphilis

A diagnostic performance study comparing the only Food and Drug Administration-approved, point-of-care (POC) treponemal test (Syphilis Health Check) and the World Health Organization pre-qualified SD Bioline POC treponemal test against a treponemal hemagglutination test (TPHA) and a sequential algorithm of nontreponemal rapid plasma reagin and TPHA found both POC tests had <85% sensitivity compared with the TPHA and <85% sensitivity and <95% specificity compared with the rapid plasma reagin and TPHA standards.
