3种梅毒抗体检测方法在梅毒诊断中的应用分析

目的探讨梅毒螺旋体抗体酶联免疫吸附试验(TP-ELISA)、梅毒甲苯胺红血清不加热血清试验(TRUST)和梅毒螺旋体抗体明胶颗粒凝集试验(TPPA)在住院肿瘤患者梅毒诊断中的临床应用,进而优化梅毒检测流程,协助临床诊断与治疗。方法用TP-ELISA和TRUST同时对住院肿瘤患者血清中梅毒抗体进行初筛,任一方法初筛阳性者均用TPPA确认;同时对梅毒抗体阳性患者的检测结果进行回顾性分析。结果 82 026例住院肿瘤患者中,TP-ELISA阳性3 618例,TRUST阳性453例,TPPA确认阳性1 684例;阳性率分别为4.41%、0.55%、2.05%;随着TP-ELISA阳性结果S/CO值的升高、TRUST阳性效价的上升,TP-ELISA、TRUST与TPPA的阳性符合率及阳性滴度也相应增加。结论 TP-ELISA检测梅毒抗体反应阳性结果S/CO与TPPA和TRUST的阳性符合率及阳性滴度呈正相关,采用TP-ELISA联合TRSUT初筛,阳性结果进行TPPA确认的检测流程,可以有效提高梅毒诊断效能和工作效率。

Application analysis of three syphilis antibody detection methods for the clinical diagnosis

Objective To explore the clinical application of treponema pallidum enzyme-linked immunosorbent assay (TP-ELISA),syphilis toluidine red unheated serum regain test (TRUST) and treponema pallidum particle agglutination assay (TPPA) for the diagnosis of syphilis,improvement of the process of sequence syphilis screening program and thus assisting clinical diagnosis and treatment of syphilis.Methods The serum samples were both screened by TP-ELISA and TRUST simultaneously.The positive was confirmed by TPPA test.Syphilis serological test results of patients were collected and retrospectively analyzed.Results The 3 618 cases out of total 82 026 serum samples were reactive by TP-ELISA,453 were reactive to TRUST,and 1 684 were confirmed positive on TPPA;thepositive rate were 4.41%,0.55%and 2.05%;The TP-ELISA,TRUST and TPPA positive conformity rate or titer were rising with the TP-ELISA S/CO and TRUST titer increasing.Conclusion There is a positive correlation of TP-ELISA S/CO among the TPPA,TRUST of positive conformity rate and titer.Using TP-ELISA and TRUST as screening,TPPA as confirmed test,the diagnostic efficiency of the process of sequence syphilis screening program can be improved.
