摘要
目的:研究体外释放酶联免疫法检测结核分枝杆菌相关γ-干扰素定量试验对结核病的诊断价值。方法:收集2008年7月-2010年10月来盐都区疾病控制中心结核病诊疗门诊就诊的肺结核、疑似肺结核及肺外结核患者共883人,采用体外释放酶联免疫法定量检测结核分枝杆菌相关γ-干扰素,判断是否感染结核分枝杆菌。结果:TB-IGRA在痰菌涂片阳性肺结核、临床诊断肺结核、肺外结核病例中检出率分别为89.11%、84.48%、85.71%,检测结果的特异性为91.57%。结论:TB-IGRA检测可作为结核分枝杆菌感染诊断的一种常规实验方法,且TB-IGRA的动态检测对抗结核治疗效果具有较好的评价作用。
Objective:To detect mycobacterium tuberculosis(MTB) related interferon-gamma(IFN-γ) in vitro release by Enzyme-linked immunosorbent assay,and evaluate the diagnosis value of the quantitative test against tuberculosis(TB).Methods:883 outpatients with active TB,suspected TB and extrapulmonary tuberculosis were recruited from Yandu district CDC from July 2008 to Oct 2010,mycobacterium tuberculosis(MTB) related interferon-gamma(IFN-γ) in vitro release was detected quantitatively by Enzyme-linked immunosorbent assay,and to judge the infection status of TB.Results:The detection rate of TB-IGRA in active TB patients with positive sputum smear was 89.11%,while the rates in clinically diagnosed TB patients and extrapulmonary tuberculosis patients were 84.48%,85.71% respectively.The test specificity was 91.57%.Conclusion:TB-IGRA can be used as a routine experimental tool for diagnosis of mycobacterium tuberculosis infection,and its dynamic surveillance can evaluate the effect of anti-tuberculosis therapy well.
