Additional information related to the test.
The Fluorescent Treponema Antibody (FTA) is recommended for follow-up of reactive nontreponemal tests for syphilis, and as a single test in patients suspected of late syphilis. The FTA may be used to resolve discrepancies between laboratory results and clinical impressions. FTA tests for syphilis may be falsely positive in some cases of systemic lupus erythematosus, pregnancy, and leprosy.
Can be used to provide additional evidence of neurosyphilis when VDRL-CSF test results are reactive.
