结核抗体滴金免疫法测定对结核性胸膜炎的诊断分析

目的 了解结核抗体（TB－Ab)对结核性胸膜炎的诊断价值。方法 用滴金免疫法测定试剂对167例结核性胸膜炎和31例非结核性胸膜炎患者分别测定胸水、血清中的TB－Ab并进行回顾性调查分析，统计试验资料。结果 167例结核性胸膜炎患者胸水、血清中TB－Ab的阳性率分别为62.9%、70.1%，胸水和／或血清检测TB－Ab诊断结核性胸膜炎敏感性为73.6%(123/167)；胸水、血清TB－Ab检测诊断结核性胸腺炎的特异性分别为93．5％、90．3％。31例非结核性胸膜炎患者的阳性率分别为6.5%和9.7%。结论 胸水及血清TB－Ab检测对结核性胸膜炎诊断和鉴别诊断有一定的临床价值。

Determination of antibody to tuberculosis by dot immunogold filtration assay in tuberculosis pleurisy

Objective To investigate the diagnostic value of TB Ab in TB pleurisy. Methods To measure TB Ab in pleural effusion and in serum of 167 TB pleurisy patients by dot immunogold filtration assay. Results The positive rates of TB Ab in pleural effusion and in serum of 167 cases were 62.9% and 70.1% respectively. Conclusion TB Ab measuring in pleural effusion and in serum is useful in the diagnosis of TB pleurisy.
