Indirect Fluorescent Antibody (IFA), Treponema pallidum substrate
CSF FTA-ABS testing is not recommended by the CDC, but may be used to rule out neurosyphilis if the CSF FTA-ABS is reported as nonreactive.
The FTA-ABS should not be used to follow treatment or establish reinfection since specific treponemal tests may remain reactive for life. FTA-ABS test for syphilis has been reported to be falsely positive in patients with diseases associated with abnormally high globulin concentrations. In the absence of historical or clinical evidence of treponemal infection, a reactive minimal result (1+) should be considered equivocal.
