Secondary Syphilis Diagnosis & Tests
The diagnosis of secondary syphilis is usually based on blood tests. An initial screening is done with the non-treponemal tests such as VDRL or RPR. If these are positive, the diagnosis is confirmed by another blood test for a specific antibody - the FTA-ABS fluorescent treponemal antibody test.
In addition to blood tests, if skin or mucous membrane lesions are present, the organism which causes syphilis may be identified on darkfield microscopic examination.
