摘要:

目的 评价改良免疫层析法在泌尿生殖道沙眼衣原体(CT)感染的检测质量,探讨其临床应用价值。方法 运用改良免疫层析法试剂盒(简称chemtrue-CT)对3家医院的261例性病门诊和健康体检者进行检测,同时以聚合酶链反应(PCR)试剂盒(简称PCR-CT)检测作为标准,分析chemtrue-CT的检测性能。结果 chemtrue-CT阳性率21.8%PCR-CT阳性率28.4%PCR-CT阳性率高于chemtrue-CTP0.01)。chemtrue-CT敏感性和特异性分别是75.7%99.5%,总体符合率92.7%。其中男性组2种方法总符合率88.8%,阳性率差异有统计学意义(P0.01);女性组2种方法总符合率为97.4%,阳性率差异无统计学意义(P0.05);女性中高危人群和健康人群2种试剂检测总符合率分别为96.8%98.2%结论 改良衣原体免疫层析法与PCR之间的检测差异正在缩小,尤其对女性人群的检测性能接近PCR

Abstract:

Objective To evaluate the performance of an improved immuno-chromatographic assay for the detection of chlamydia trachomatisCT in genitourinary tract infection and then to assess the significance of clinical application. Methods A total of 261 patients from sexually transmited infection clinics and healthy subjects in 3 hospitals of Shanghai were enrolled and determined by an improved immuno-chromatographic assay kitchemtrue-CT. The polymerase chain reactionPCR kitPCR-CT as a reference standard was used to analyze the performance of chemtrue-CT. Results The total positive rate of PCR-CT28.4% was higher than that of chemtrue-CT21.8% P0.01. The sensitivity and specificity of chemtrue-CT were 75.7% and 99.5% respectively. The overall coincidence rate between
the 2 assays was 92.7% with male group's coincidence rate 88.8%
P0.01 and female group's coincidence rate 97.4%P0.05. The 2 assay resultswere similar with an overall coincidence rate of 96.8% and 98.2% in female group. Conclusions The performance difference between chemtrue-CT and PCR-CT is narrowing. Particularly for female group chemtrue-CT shows acceptable performance in comparison with PCR-CT.
