The reasonable explanation of your situation is that the TP antibody test card for syphilis (colloidal gold method) is weak positive or false positive. There are many factors affecting this rapid detection, and the false positive rate is very high. Moreover, the rapid detection only has negative and positive results, and there is no weak positive, so it is not excluded that it is a false positive.

TPPA detected a specific antibody against Treponema pallidum. As long as this antibody has been infected with syphilis, whether it is cured or not, it is positive for life, and there is no possibility of turning negative through treatment. As long as TPPA is negative, the possibility of syphilis infection can be ruled out.

So you are not infected with syphilis, and the quick test result is false positive.
