How does syphilis come about?

First of all, syphilis weak positive, often suggest that may be infected with syphilis before, but need to see which test is weak positive, syphilis specific antibody or syphilis titer test. Second, if syphilis specific antibody is weak positive, then it may be infected with syphilis before, but this situation can not be diagnosed, it is recommended to check again a month later. Third, if syphilis titer test 1:1 for weak positive words, then it is only suspected that there may be syphilis infection, but there may also be this false positive, often need to further check syphilis specific antibody detection, to see if it is also positive. If double positive words, then you can diagnose syphilis infection.
