Clinical Significance
Serological test for syphilis. This is a Treponema-specific test and may be positive in all stages of syphilis. It may be positive with treponemal infections other than syphilis (bejel, pinta, yaws). Like FTA-ABS and TP-PA, once positive, it remains so; it cannot be used to judge theeffectiveness of treatment. The test is not applicable to CSF.
