My first exposure happened in April 2015,and the othet exposure was in December 2015.I went for test for Rpr and tppa in January 2016, 37days after the last exposure. After that, I was still worried about it so I got test in early June 2016,tpha alone , negative.
Here's my questions.
1.I saw views that tppa(tpha) test alone cannot completely exclude the infection, but I saw many studys say they are nearly 100% accurate 3 months after exposure, which should I trust?
2. Are my test results conclusive? Especially the tpha test in June.
3.Do I need further tests?
