    癌胚抗原~~

    血清癌胚抗原:(英文名:CEA)
     
    正常范围:<5.Oμg/L。    酶联免疫吸附试验(ELISA):<25ng/ml

    检查介绍:癌胚抗原最初发现于结肠癌及胎儿肠组织中,故名。血清CEA升高,除见于消化道癌外,也见于其他系统。

    临床意义:CEA测定主要用于结肠直肠癌、胃癌、胰癌、肝细胞癌、肺癌、乳癌以及甲状腺髓质癌的临床监测,亦见于绒毛膜癌、骨癌、前列腺癌和卵巢癌,但无早期诊断价值。
    此外,CEA轻度增加也见于某些良性消化道疾病如肠梗阻、胆道梗阻、胰腺炎、肝硬化结肠息肉溃疡性结肠炎以及吸烟者和老年人。这些消化道良性疾病患者中25%的人血清CEA可暂时性升高。
