甲胎蛋白(AFP)在原发性肝癌患者的血清中检出率很高。近来通过放射免疫检定,已能对AFP进行微量定量,并已证明在原发性肝癌以外的肝脏疾患时也存在微量的AFP。作者观察急性肝炎患者28例(包括亚急住肝炎5例),对照健康成人56名,报告其AFP的变动经过,并讨论了它的临床意义。健康成人56名血清AFP浓度都在10毫微克/毫升以下,因此作者等把10毫微克/毫升以下作为正常值。急性肝炎时,于发病初期大部分在10毫微克/毫 Alpha-fetoprotein (AFP) is highly detectable in the serum of patients with primary liver cancer. AFP has been recently quantified by radioimmunoassay and trace amounts of AFP have also been demonstrated in liver disorders other than primary liver cancer. The authors observed 28 patients with acute hepatitis (including subacute hepatitis 5), compared with 56 healthy adults, reported changes in its AFP, and discussed its clinical significance. In 56 healthy adults, serum AFP concentrations are below 10 ng / ml, so the authors wait for 10 ng / ml or less as a normal value. Acute hepatitis, most of the early onset of 10 ng / milliliter
