结核抗体检测在结核病诊断中的意义

目的探讨结核抗体（TB-Ab）检测在结核病诊断中的意义。方法对564例患者进行血清或胸（腹）水TB—Ab检测，其中活动性结核患者508例，非结核患者56例。结果活动性结核患者中，涂阳肺结核TB—Ab阳性率为70．8％；涂阴结核并胸水32例，腹水4例，腹水或胸水TB-Ab（阳性率为44．4％，另424例涂阴结核TB-Ab阳性168例，阳性率39．6％，活动性结核TB-Ab总阳性率约42．9％。非结核患者假阳性率为10．7％。结核患者与非结核患者TB-Ab检测有显著差异（X^2=22．65，P〈0．01）。结论TB-Ab检测对活动性结核的诊断有价值，但敏感性较低，可作为结核病的快速辅助诊断手段，但尚须临床进一步研究。

The clinical value of tuberculosis antibody in diagnosis of tuberculosis

Objective To evaluate the diagnostic value of tuberculosis antibody. Methods 564 patients re-ceived detection of serum,in which,508 cases suffered from active tuberculosis(TB) and 56 cases suffered from non-active TB. Results 508 cases with active TB received detection AB-Ab in serum, 48 cases were bacteriological smear positive cases, the rate of serum TB-Ab positive cases was 70.8% (34/48), the rate of pleural effusion or ascites TB-Ab positive cases was 44.4% (16/36), the rate of serum TB-Ab positive cases in another 424 cases with bacteriologi-cal smear negative TB was 39.6% (168/424). There was significant difference between active TB group and non-ac-tive TB group(χ2= 22.65, P<0.01). Conclusion It is useful for diagnosis of active TB by detecting TB-Ab. It may be a rapid auxilliary diagnostic way in TB diagnosis.
