Generally, the initial screening is to check RPR or TRUST, and the confirmation is to check TPPA or TPHA. It is better to check these two experiments. Double negative can rule out syphilis, double positive can be diagnosed as syphilis, other TPPA is negative, and trust is false positive. TPPA positive and trust negative are false positives of syphilis or TPPA in the past.

Yes, RPR syphilis test is negative, which means you are not infected with this virus. Don't worry, if the test is positive, it means you are infected. I just don't know how long you have been exposed to this virus, because this virus infection also has a window period, and it takes about 10- 15 days to detect it. After being infected by Treponema pallidum, TPPA can be cured for life. RPR can be negative or even positive, and the titer is low. After anti-plum therapy, TPPA can turn negative or positive for life about 1 year. Whether syphilis is completely cured depends mainly on RPR.
