Hello everyone, my last sexual contact was little over two years ago with my ex girlfriend. I accidentally came into contact with her period blood orally while doing oral sex. I recently got tested for syphilis and others and it came back as VDLR-RPR: Negative titer. However, after doing some reading, I saw that after a period of time the accuracy of these tests decreases, but I couldn’t understand the exact timeframe. How accurate is mine condisering the time gap between the exposure and testing? Should I get tested with something different? I’m not sure about the syphilis statistics of my country, but as far as I know, it’s been on the rise. I appreciate your input in advance.
