摘要
目的探讨酶联免疫斑点试验(ELISPOT)检测结核分枝杆菌特异抗原T淋巴细胞的频率,在快速诊断结核病中的临床应用价值。方法利用ELISPOT检测对结核菌特异抗原刺激反应,分泌γ干扰素的效应T淋巴细胞数量方法,测定30名健康体检者,24例丙肝患者,65例非结核呼吸道疾病患者和112例结核病患者外周血单个核细胞中结核菌抗原特异的T淋巴细胞的频率。结果112例结核病患者中,107例结核病患者结核抗原特异ELISPOT阳性,提示方法敏感度为95.5%,30名健康对照中,2名健康体检者阳性,其他健康体检者阴性,24例丙肝患者和65例非结核呼吸道疾病患者均为阴性,方法的特异度为93.3%。结论ELISPOT是较灵敏和特异的快速检测结核菌感染的方法,可用于结核病的快速诊断。
