摘 要:目的对梅毒血清学检测流程进行临床流行病学初步评价,制定出结合实际的梅毒螺旋体血清学检测方案。方法同步进行RPR,ELISA,TPPA扣TP核酸定量检测。结果几种检测方法的灵敏度(RPR+ELISA+TPPA)〉(RPR+ELISA)〉(RPR+TPPA)〉ELISA〉TPPA〉RPR;RPR,ELISA,TPPA三种方法的特异度均高于96%,将实验组合后(RPR+TPPA)〉(RPR+ELISA)和(RPR+ELISA+TPPA);误诊率(RPR+ELISA)〉(RPR+TPPA)和(RPR+ELISA+TPPA);(RPR+ELISA+TPPA)组合的漏诊率为0,(RPR+ELISA)组合的漏诊率为0.99%,(RPR+TPPA)组合的漏诊率为3.98%;正确指数(RPR+ELISA+TPPA)〉(RPR+ELISA)〉(RPR+TPPA)。血清学标本的TP核酸定量检测阳性率只有1%。结论将RPR,ELISA和TPPA三种方法一起联检,是目前梅毒筛查和诊断最有效、最准确的方案,TP核酸定量检测不适合梅毒的血清学诊断。Objective To preliminary assessment the flow sheet of syphilis serological detection by clinical epidemiology and enact practical measurement schema for syphilis serological detection. Methods Perform RPR,ELISA, TPPA and real time PCRsimultaneously with stand operation protocol. Result The sensitivity of combined methods from high to low were (RPR + ELISA + TPPA ) 〉 (RPR +ELISA ) 〉 (RPR + TPPA ) 〉 ELISA 〉 TPPA 〉 RPR. The specificity of RPR, ELISA and TPPA were over 96%. Combined RPR, ELISA and TPPA, the specificity were (RPR+ TPPA) 〉 (RPR+ ELISA) and (RPR+ELISA+TPPA). As to misdiagnosis rate, (RPR+ELISA)〉(RPR+PPA) and (RPR+ELISA+TPPA). The omission diagnose rate of (RPR+ELISA+TPPA), (RPR+ELISA) and (RPR+TPPA) were 0,0. 99% and 3. 98% respectively. As for precision index, (RPR+ELISA+TPPA)〉 (RPR+ELISA)〉 (RPR+TPPA). Positive rate of real time PCR of serological sample was 1%. Conclusion Combining RPR,ELISA and TPPA was a more effective and ac- curate scheme. Serological sample was not suitable for serological diagnosis with real time PCR.
