各种研究已证明,肝细胞癌患者血清中存在着甲胎蛋白(AFP),AFP的测定已成为检查有无肝细胞癌的常规.当用免疫扩散法测量血清AFP时,检测的下限是在1000～3000ng/ml,美国肝细胞癌患者中大约50%低于这个水平.放射免疫技术的发
Various studies have shown that the presence of AFP in the serum of patients with hepatocellular carcinoma and the determination of AFP has become the routine test for the presence or absence of hepatocellular carcinoma.When serum AFP is measured by immunodiffusion, the lower limit of detection is between 1000 ~ 3000ng / ml, about 50% of the American patients with hepatocellular carcinoma is lower than this level.
