1、荧光梅毒螺旋抗体吸收试验(FTA-ABS Test):此法是较敏感和较特异的螺旋体试验。 2、梅毒螺旋体血凝试验(TPHA):敏感性和特异性均高,操作简便,但对一期梅毒不如FTA-ABS试验敏感。 3、梅毒螺旋体制动试验(Treponema Pallidum immobilization ,TPI);用Nichol株螺旋体(活的)加病人血清(含抗体)后,在补体的参与下可...
白细胞计数≥10×106/L,蛋白量>500mg/L,且无其他引起这些异常的原因。脑脊液VDRL试验(或RPR/TRUST试验)或FTA-ABS试验(或TPPA/TPHA试验)阳性。 d)组织病理检查 有三期梅毒的组织病理变化。 04 隐性梅毒(潜伏梅毒) a)非梅毒螺旋体血清学试验 阳性。 b)梅毒螺旋体血清学试验 阳性。 c)脑脊液检查 有条件时可进...
(一)早期梅毒应做梅毒螺旋体暗视野显微镜检查。 (二) 梅毒血清反应素试验(如VDRL、USR或RPR试验),有必要时再做螺旋体抗原试验(如FTA-ABS或TPHA试验)。 (三)脑脊液检查,以除外神经梅毒,尤其无症状神经梅毒,早期梅毒即可有神经损害,二期梅毒有35%的病人脑脊液异常,因此要检查脑脊液。 (四)基因诊断检测。 鉴别诊断 ...
目前,梅毒筛查与诊断更多地倾向于用梅毒螺旋体特异性抗体检测的反向检测流程,如欧洲推荐梅毒螺旋体抗体(TPEIA)或梅毒螺旋体血细胞凝集试验(TPHA)用于筛查,条件允许可做其他检测,结果不一致时用免疫印迹法排除。现在,多数国家基本上首先采用梅毒螺旋体特异性抗体进行筛查,如阳性再采用梅毒非特异性抗体检测,用于临床...

treponemal tests: Highly sensitive; however, they are nonspecific and tend to be positive for life.[129]Thus, they are more useful to rule out neurosyphilis when the pretest probability is low to moderate or the VDRL is negative.[40][129]These are the FTA-ABS, TPPA, TPHA, and EIA ...
