What does a reactive syphilis test mean?

Interpretation of reactive tests A reactive treponemal test most likely indicates infection by T pallidum but is not sufficient to determine disease activity and make treatment decisions (table 1). A reactive test can be seen in patients with a history of syphilis who has been treated.
