- Description
Clinical Significance: This immunofluorescence assay (IFA) for T pallidum antibody, also called the fluorescent treponemal antibody absorption assay (FTA-ABS), may aid in the diagnosis of neurosyphilis. However, the preferred initial test for neurosyphilis evaluation is the Venereal Disease Research Laboratory (VDRL) test on cerebrospinal fluid (CSF). For the diagnosis of neurosyphilis, all serum and CSF tests for syphilis should be evaluated in conjunction with clinical presentation.
