摘要 目的探讨IFN-γ释放实验(IGRA)和结核抗体检测在肺结核诊断中的临床价值。方法选取2015年4月至2016年3月该院确诊的158例肺结核患者(肺结核组)及162例其他呼吸道疾病患者(对照组)为研究对象,进行IGRA实验和结核抗体检测,比较2种方法检测2组患者的阳性率结果。结果 IGRA实验和结核抗体检测在肺结核组的阳性率分别为80.38%(127/158)和50.63%(80/158),均高于对照组,差异有统计学意义(χ2分别为6.008和132.662,P<0.05)。IGRA实验与结核抗体检测结果的符合率为44.94%,IGRA检测阳性率高于结核抗体检测,差异有统计学意义(χ2=4.516,P<0.05)。IGRA实验的灵敏度、特异度、阳性预测值、阴性预测值、准确率分别为80.38%、83.95%、83.01%、81.44%、82.19%,结核抗体检测分别为50.63%、62.96%、57.14%、56.67%和56.88%。结论 2种检测方法为肺结核诊断提供有效的实验数据,IGRA实验具有更高的灵敏度和特异度,但费用较高,尚不能大规模应用于临床。
