目的探讨梅毒螺旋体酶联免疫吸附试验(TP-ELISA)与梅毒螺旋体抗体凝集法(TPPA)在梅毒螺旋体检测中的应用。方法 450例阴性标本和40例梅毒阳性标本,采用TP-ELISA与TPPA检测血清梅毒螺旋体结果进行分析,比较两种方法检测梅毒螺旋体的差异。结果 TP-ELISA与TPPA各检出梅毒螺旋体阳性41例和40例,阳性检出率分别为8.4%和8.2%,TP-ELISA与TPPA阳性检出率比较差异无统计学意义(P>0.05)。两种方法的阳性符合率为97.6%,阴性符合率为99.8%,总符合率为99.8%。TP-ELISA的假阳性率为0.2%,TPPA无假阳性。结论为实现大批量自动化处理和提高检测的准确性,对于梅毒检验工作使用TP-ELISA筛查联合TPPA确认更为快速,准确。
Objective To investigate the application of TP-ELISA and TPPA in the detection of Treponema pallidum. Methods 450 cases of negative specimens and 40 cases of syphilis positive specimens were detected by TP-ELISA and TPPA serological detection of Treponema pallidum, the two methods to detect the difference between Treponema pallidum. Results The positive rates of TP-ELISA and TPPA were 41% and 40%, respectively, and the positive rates were 8.4% and 8.2% respectively. The positive rates of TP-ELISA and TPPA were not significantly different (P> 0.05) . The positive coincidence rate of the two methods was 97.6%, the negative coincidence rate was 99.8%, the total coincidence rate was 99.8%. TP-ELISA false positive rate of 0.2%, TPPA no false positive. Conclusion In order to achieve high-volume automated processing and improve the accuracy of detection, TP-ELISA screening combined with TPPA is more rapid and accurate for syphilis testing.
