【摘要】 目的探讨血清抗结核分支杆菌抗体对活动性结核病的诊断价值。方法采用快速酶联吸附法（ＥＬＩＳＡ）检测血清抗ＰＰＤＩｇＧ在各类结核病中的特异性、敏感性及与痰菌、病情的关系。结果血清抗ＰＰＤＩｇＧ诊断结核病的特异性为８９８％，敏感性为８２９％，其阳性率与痰菌关系不大，与病情变化有一定的相关性。结论血清抗ＰＰＤＩｇＧ检测是活动性结核病一项有价值的诊断方法，并可用于评价结核病治疗的转归。更多还原

【Abstract】 Objective To study the values of detecting antibodies of mycobacteria tuberculosis in the diagnosis of tuberculosis in active period. Methods Enzyme linked immunosobent assay (ELISA) was used to compare the specificity and sensitivity of anti PPD IgG in various kinds of tuberculosis and bacteria in the sputum and conditions. Results The specificity and sensitivity of seral anti PPD IgG were 89 8% and 82 9% respectively, in which the positive rate showed little relationship with bacteria in the sputum and some association with the conditions of the disease. Conclusion The detection is a valuable diagnostic indicator for active tuberculosis and can be used in evaluating prognosis.更多还原
