Treponemal tests (TP-PA, FTA-ABS) are confirmation tests that are highly specific for syphilis but remain positive for life even after successful treatment, so they cannot be used alone to assess treatment outcome.<\/p><\/div> <div class=\"schema-faq-section\" id=\"faq-question-2\"><strong class=\"schema-faq-question\">If my VDRL or RPR is positive, does it mean I have syphilis?<\/strong> <p class=\"schema-faq-answer\">A positive VDRL or RPR is a strong indicator but not a definitive diagnosis. These screening tests can occasionally produce false positives due to other conditions such as autoimmune diseases or viral infections. A confirmatory treponemal test (TP-PA or FTA-ABS) is always required to make a definitive diagnosis of syphilis.<\/p><\/div> <div class=\"schema-faq-section\" id=\"faq-question-3\"><strong class=\"schema-faq-question\">Why does my treponemal test stay positive even after treatment?<\/strong> <p class=\"schema-faq-answer\">Treponemal tests detect specific antibodies against the syphilis bacterium that persist in the bloodstream for life once produced, even after the infection has been completely cured. This is a normal finding and does not mean the infection is still active. Treatment success is monitored using nontreponemal tests (VDRL or RPR), which should show a declining titer after effective treatment.<\/p><\/div> <div class=\"schema-faq-section\" id=\"faq-question-4\"><strong class=\"schema-faq-question\">How do doctors know if syphilis treatment is working?<\/strong> <p class=\"schema-faq-answer\">Treatment response is tracked by monitoring the VDRL or RPR titer over time. After successful treatment, the nontreponemal titer should decrease fourfold or more within 6&#8211;12 months. A stable or rising titer may indicate treatment failure or reinfection, requiring further evaluation by a specialist.<\/p><\/div> <div class=\"schema-faq-section\" id=\"faq-question-5\"><strong class=\"schema-faq-question\">Is syphilis curable?<\/strong> <p class=\"schema-faq-answer\">Yes, syphilis is highly curable, especially when diagnosed and treated early. The standard treatment is penicillin G injection, with the dose and duration depending on the stage of infection. Early diagnosis, correct treatment, and regular follow-up blood tests are essential to ensure complete cure and prevent complications or transmission to partners.<\/p><\/div><\/div>\n\n\n\n<p class=\"wp-block-paragraph translation-block\"><strong>Avis de non-responsabilit\u00e9 :<\/strong> Ce contenu est r\u00e9dig\u00e9 et revu par le Dr Soarawee Weerasopone, urologue certifi\u00e9 au si\u00e8ge de Bangkok Hospital.
