【摘要】 比较几种方法对３０例胸腔积液的病因诊断价值。发现胸膜活检术简便易行、安全可靠；胸液结核菌脱氧核糖核酸聚合酶联反应具有快速、高灵敏、高特异性；胸液癌胚抗原检测对初步鉴别结核或肿瘤所致胸腔积液有实用价值；测定胸液／血乳酸脱氢酶和胸液沉渣找癌细胞及结核杆菌和结核杆菌培养，其实用价值有限。更多还原

【Abstract】 everal common methods were observed and compared,pleurisy biopsy is a simple andsafe, reliable and economic pathologic diagnostic method which should be specially promotedin the lower medical units. The specificity of PCR-TB-DNA is very high but the sensitivenessis lower. The measurement of CEA is useful to diagnose pleural effusion induced by tubercu-losis or tumor. The positive rate of the measurement of LDH,anti-PPD antigen,carcinomacell,tubercle bacillus and culture of tubercle bacillus is too low,and so is the practical valuelow.更多还原
