摘要: 目的 评价新的国产结核分枝杆菌相关γ-干扰素定量检测试剂盒(TB-IGRA)——体外释放酶联免疫法诊断结核病的敏感性和特异性。 方法 采用TB-IGRA试剂盒对319例肺结核、23例肺外结核、39例排除结核的肺部疾病和104例健康人群的血清标本进行检测,同时与澳大利亚Cellestis公司的QuantiFERON-TB GOLD in tube(QFT-GIT)试剂进行平行比较分析。 结果 采用TB-IGRA试剂,检测肺结核病人的敏感性为90.9%,肺外结核的敏感性为78.3%,特异性为76.9%;采用QFT-GIT试剂,检测肺结核病人的敏感性为88.4%,肺外结核的敏感性为78.3%,特异性为80.4%,2种试剂进行平行比较,敏感性和特异性方面差异无统计学意义。 结论 TB-IGRA试剂盒对诊断结核病有较高的敏感性和特异性,可用于结核病尤其是涂阴肺结核和肺外结核的辅助诊断。

Abstract: Objective To evaluate the sensitivity and specificity of interferon-gamma (IFN-γ) quantitative detection kit (TB-IGRA, Beijing Wantai Biological Pharmacy Corporation Ltd.) for the diagnosis of tuberculosis (TB).  Methods We detected the serum specimens from 319 patients with pulmonary TB, 23 patients with extrapulmonary TB, 39 patients with non-TB lung disease and 104 healthy people with TB-IGRA and QuantiFERON-TB GOLD in tube (QFT-GIT, Cellestis, Australia) simultaneously, and compared their Results .  Results The sensitivities of TB-IGRA for TB and extrapulmonary TB were 90.9% and 78.3%, respectively, and it’s specificity was 76.9%. The sensitivities of QFT-GIT for TB and extrapulmonary TB were 88.4% and 78.3%, respectively, and it’s specificity was 80.4%. There was no significant difference between these two kits. Conclusion TB-IGRA is a highly sensitive and specific kit in the diagnosis of TB, and it can be used in the accessory diagnosis of tuberculosis, especially extrapulmonary tuberculosis.
