目的　探讨结核性胸膜炎的检测方法 ,提高阳性检出率。方法　将已确诊的 82例结核性胸膜炎患者分别进行抗PPD IgG、PCR检测及两种方法联合检测。结果　两种方法单独应用检出率分别为 70 .5 %、5 9 .8% ;联合检测的检出率为 80 .5 %。结论　胸水抗PPD IgG和PCR联合检测能够提高对结核性胸膜炎的阳性检出率 Objective To explore the detection of tuberculous pleurisy and improve the positive detection rate. Methods 82 cases of tuberculous pleurisy diagnosed were tested by anti-PPD IgG, PCR and two methods. Results The detection rates of the two methods alone were 70.5% and 59.8% respectively. The detection rate of combined detection was 80.5%. Conclusions The combined detection of pleural effusion with anti-PPD IgG and PCR can improve the positive detection rate of tuberculous pleurisy
