Treponema pallidum particle assay梅毒螺旋体明胶凝集试验
1.MethodsSerum samples were determined by rapid plasma reagin test(RPR) and Treponema pallidum particle assay(TPPA).方法快速血浆反应素环状卡片试验(RPR)及梅毒螺旋体明胶凝集试验(TPPA)。
3)TPPA梅毒螺旋体明胶凝集试验
1.[Methods]Taking TPPA as the golden standard method of syphilis detection,the sensitivity and specificity of ELISA and TRUST were evaluated.[方法]以梅毒螺旋体明胶凝集试验(TPPA)为检测梅毒的金标准方法,使用常用的梅毒螺旋体感染诊断TRUST、ELISA和TPPA试剂进行检测,评价酶联免疫吸附试验(ELISA)、和甲苯胺红试验(TRUST)的敏感性和特异性。
2.Methods Serum samples of 784 visitors to STD clinics were tested by ELISA and FTAABS,and the positive samples by these two tests were retested by TPPA and Western blot.方法抽取性病门诊就诊者的静脉血,用梅毒酶联免疫吸附试验(ELISA)检测梅毒抗体,同时用梅毒螺旋体明胶凝集试验(TPPA)检测同一份血清,二种方法均为阳性者用荧光梅毒螺旋体抗体吸收法(FTA-ABS)检测及免疫印迹法(WB)确认,对试验数据进行统计分析和检查。
3.Objective To analyze the syphilis toluidine red unheated serum reagin test(TRUST),rapid plasma reagin circle card test(RPR),syphilis enzyme-linked immunosorbent assay(TP-ELISA),and the gelatin agglutination of Treponema pallidum test(TPPA) test for syphilis at the application of values,set up the laboratory for syphilis testing and reporting system.目的评价梅毒甲苯胺红不加热血清反应素试验(TRUST)、快速血浆反应素环状卡片试验(RPR)、梅毒酶联免疫吸附试验(TP-ELISA)和梅毒螺旋体明胶凝集试验(TPPA)在梅毒检测中的应用价值。
4)19S-IgM-TPPA19S-IgM-梅毒螺旋体明胶凝集试验
1.Objective To evaluate the clinical significance of 19S-IgM-TPPA assay on detection of specific 19S-IgM antibody in syphilitic patients.目的评价19S-IgM-梅毒螺旋体明胶凝集试验(19S-IgMTPPA)法检测梅毒患者血清中特异性TP-IgM抗体的临床意义。

螺旋体血细胞凝集试验螺旋体血细胞凝集试验 诊法。梅毒实验 室诊断方法之一。原理:抗原是把Nichols株螺旋体用超声波打碎成可溶性抗原,再与已 经福尔马林固定,用鞣酸处理的绵羊红细胞混合,以羊血细胞为载体并吸附螺旋体可溶性 抗原而成。被检测的血清标本是用Reiter株非致病性螺旋体经半固定培养基繁殖一定数量后 ,高压灭菌及高速离心后的上清液,即为吸收剂。用此吸收剂稀释血清,可将血清中非特异 性 抗体吸收掉,并不影响特异性抗体的滴度。取经吸收剂稀释并吸收过的血清于血凝反应板上 ,每孔25μl,用特制的滴管于已滴加25μl血清的孔内再加入已吸附抗原的羊血细胞3滴( 75μl)将反应板放在微型振荡器上混合5分钟,使致血细胞与吸收过的血清充分混合, 放于25℃4小时或4~8℃冰箱中 过夜即可观察结果。对照非致敏血细胞及阴性、阳性血清,结果明显,容易判定。
