为何检测?

筛查某些肝脏、睾丸或卵巢肿瘤及监测治疗。

何时检测?

当医生怀疑病人患有某些肝脏、睾丸或卵巢肿瘤时,或者在这些肿瘤治疗当中或完成治疗后,或是病人患有慢性肝炎、肝硬化时,可以检测甲胎蛋白。

何种样本?

采自肘静脉的血液样本。

是否需要作试验前准备?

不需要。

检测样本

检测什么?

甲胎蛋白是由胎儿组织(尤其是肝脏)和肿瘤组织合成的一种蛋白质。大多数的肝细胞癌患者甲胎蛋白含量是增高的,在一些睾丸和卵巢肿瘤患者体内也存在该种蛋白。

        甲胎蛋白具有几种不同的异质体。一般来说,当医生要求AFP检测时,尤其要求检测总的甲胎蛋白时,包括甲胎蛋白所有的异质体。甲胎蛋白试验最早由美国应用。

        甲胎蛋白的异质体之一,由于能够与扁豆凝集素结合而被命名为L3。AFP-L3%试验是一种能够测定总甲胎蛋白中AFP-L3异质体比例的新方法。AFP-L3百分率越高,则近期发生肝细胞癌的风险越高,同时由于L3相关癌症更具有侵袭性,这种病人的预后也越差。目前AFP-L3%试验在美国开展不多,在另外一些国家如日本,应用得较广泛。

测试样本如何采集?

自肘静脉采集血液样本。

是否需要进行任何试验前准备以保证样本的质量?

不需要试验前准备。
