摘要:目的 探讨胸液和血清的腺苷脱氨酶(ADA)以及血清结核抗体(TBAb)检测在胸腔积液鉴别诊断上的价值。 方法 对2001～2004年确诊的结核性胸腔积液51例、恶性胸腔积液34例，其它渗出液27例及漏出液12例患者的胸腔积液、血清进行ADA和TBAb检测，对结果进行统计学分析。 结果 结核性胸腔积液组的胸液ADA值显著高于其它三组(P<0.01)，血清ADA值与其它组比较则无差异。血清TBAb阳性率高于其它三组(P<0.05);恶性胸腔积液组血清ADA低于其它三组(P<0.05);漏出液组胸液ADA值均<35U/L。 结论 ADA对结核性胸腔积液诊断的敏感性、特异性均高，有重要诊断价值。血清TBAb对结核性胸腔积液有一定的诊断价值。
