Evaluation of RPR, TPHA test results and diagnostic algorithms used in syphilis diagnosis

Abstract: Amaç: Ülkemizde, sifiliz bildirimi zorunlu bir hastalık olmasına rağmen, bildirim sistemindeki sorunlar nedeniyle hastalığın gerçek sıklığını tahmin etmek güçtür. Bu çalışmada, RPR veya hızlı test sonuçları pozitif olarak saptanan ve merkezimize doğrulama amacıyla gönderilen serum örnekleri RPR ve TPHA testleri kullanılarak yeniden çalışılmıştır. Sifiliz tanısında kullanılan konvansiyonel ve ters algoritmaların, elde edilen veriler doğrultusunda değerlendirilmesi de amaçlanmıştır. Gereç ve Yöntem: Ocak 2014-Ka… Show more

“…However, 37 (40%) of these RPR negative patients were revealed to be positive for TP-HA performed as a second treponemal test; thereby, RPR was concluded to be false negative. According to a study by Sonmez et al (16) including 362 probable syphilis patients according to the results of rapid diagnostic tests, 311 patients (85.9%) were diagnosed as syphilis when the screening was performed with treponemal test (TP-HA) and reversed algorithm. However, only 173 patients (47.8%) could be diagnosed as syphilis when testing was performed with nontreponemal analysis and classical algorithm, meaning that when the traditional algorithm was used, 4 out of 10 syphilis patients could be to be undiagnosed.…”
