简介:摘要目的探讨联合检测癌胚抗原(CEA)、腺苷脱氨酶(ADA)、乳酸脱氢酶(LDH))在胸腔积液性质鉴别诊断的价值。方法采用回顾性研究方法,2005-2011年期间收治的181例胸腔积液患者,分别以胸腔积液和血清分别采用酶免疫学化学发光法进行CEA、ADA、LDL含量测定。结果结核组胸水ADA及其比值显著高于恶性组(P<0.05),恶性组胸水、血清CEA及其比值和胸水LDH显著高于结核组(P<0.05)。三项指标联合检测恶性胸腔积液的敏感度72%、特异度92.7%、准确度82.3%。结论联合检测癌胚抗原(CEA)、腺苷脱氨酶(ADA)、氢酶(LDH))对不明原因胸腔积液的诊断和鉴别诊断有重要意义,可提高诊断正确率。
