摘要
目的:考察全自动微粒子化学发光免疫实验(CMIA)与TP-Ig M抗体检测(TP-ELISA)在梅毒检测中的应用效果差异。方法:采用TPPA法作为金标准检测1000例住院患者血清标准,评价CMIA与TP-ELISA在梅毒检测中敏感性和特异性。结果:金标准中1000例血清标本梅毒检出率为12.3%,CMIA阳性检出率为12.9%,TP-Ig M为11.7%。CMIA法灵敏度为98.4%(121/123),特异性为99.1%(869/877),阳性预测值为93.8%(121/129),阴性预测值为99.8%(869/871)。TP-ELISA法灵敏度为89.4%(110/123),特异性为99.2%(870/877),阳性预测值为94.0%(110/117),阴性预测值为98.5%(870/883)。两组间灵敏度和阴性预测值存在显著差异(P<0.05)。结论:CMIA的灵敏性和阴性预测值优于TP-ELISA法,可以替代TP-PA成为梅毒检测的血清学检测首选方法。
Objectives: To investigate the effect of automatic particle chemiluminescence immunoassay( CMIA) and TP- Ig M antibody( TP- ELISA) in the detection of syphilis. Methods: Serum sample of 1000 hospitalized patients were detected by TPPA as gold standard,and the sensitivity and specificity of CMIA and TP-ELISA in the detection of syphilis were evaluated. Results: The positive rate of syphilis was 12. 3% in 1000 patients. The positive rates of CMIA and TP- Ig M were 12. 9% and11. 7% respectively. The sensitivity and specificity of CMIA was 98. 4%( 121 /123) and 99. 1%( 869 /877),the positive predictive value was 93. 8%( 121 /129),and the negative predictive value was 99. 8%( 869 /871). The sensitivity of TP- ELISA was 89. 4%( 110 /123),specificity was 99. 2%( 870 /877),the positive predictive value was 94%( 110 /117),and the negative predictive value was 98. 5%( 870 /883). There were significant differences between the two groups in the sensitivity and the negative predictive value( P〈0. 05). Conclusion: The sensitivity and negative predictive value of CMIA is better than these of TP- ELISA,and it can replace TP- PA as the first choice for the detection of syphilis.
