利用电泳和 Laurell 法可以进行血清α_2H 的定性和定量检查。血清α_2H 为一种含铁蛋白,在胎儿脐带血清约占10%,正常成人血清中不存在。与αF不同,不仅在原发性肝癌,在胃癌、胰癌、肺癌患者血清中也含有α_2H。在这些癌的患者血清中α_2H 占12～34%。值得注意的是,在急性骨髓性白血病患者血清中α_2H 高达93%。在多发性骨髓瘤、淋巴肉瘤、何杰金氏病中有少数患者血清出现α_2H。在恶性肿 The use of electrophoresis and Laurell method can be qualitative and quantitative serum α_2H check. Serum α_2H is a ferritin, which accounts for about 10% of fetal umbilical cord serum and is absent from normal adult serum. Unlike αF, α 2 H is not only found in primary liver cancer, but also in serum of patients with gastric cancer, pancreatic cancer and lung cancer. In these patients with cancer serum α_2H 12 to 34%. It is noteworthy that in patients with acute myelogenous leukemia α_2H up to 93%. In multiple myeloma, lymphosarcoma, Hodgkin’s disease in a small number of patients with serum α_2H. In malignant swelling
