I donated blood for the first time and got to know that I have syphilis because my VDRL/RPR was positive with titer 1
Hi and thanks for using this forum for your health concerns. I am so sorry to hear about what you are going through. Not all cases of primary syphilis really stand out clear that you may suspect having the infection. You may not have ever noticed you had the infection though you have suffered from it. These are cases of asymptomatic primary infection. For this test to be positive consistently, and FTA which is specific to Syphilis being positive deserve to be treated. I will strongly advise you get treated and so like syphilis which has lasted more than a year because we don't really know when this happened. The side effects of the commonly used Chat Doctor.  Treating now is the best way to go. If you don't have any infection, the side effects are still the same and not any more dangerous than with having the disease. Hope this helps... Welcome to ask more questions and wish you good health.
