Abstract
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. Key words: Tuberculosis; Antiboies, bacterial
