The Fluorescent Treponemal Antidogy (FTA) may be used to resolve discrepancies between laboratory resutls and clinical impressions. FTA tests for syphillis may be false positive in cases of systemic lupus erythematosus. The FTA test is not recommended for cerebrospinal fluid specimens. For CSF specimens the VDRL-CSF test is recommended. Reactive-minimal final reports indicate the initial specimen submitted has been tested twice and cannot be interpreted as either reactive or non-reactive.If it is the second specimen submitted on a patient and the report is again reactive-minimal, it is impossible to state definitively that the patient does or does not have a syphillitic infection.
