放射免疫分析法检测甲胎蛋白(AFP),具有灵敏度高、特异性强、并能准确定量的优点,有助于肝癌的早期诊断以及其疗效和预后的判断。放射免疫火箭电泳自显影(简称放射火箭电泳)法检测AFP的灵敏度和准确性虽不如放射免疫饱和分析法,但前者不需要特殊的放射性测量仪器,便于普及推 Radioimmunoassay for the detection of alpha-fetoprotein (AFP) has the advantages of high sensitivity, specificity, and accurate quantification, which is helpful for the early diagnosis of liver cancer, as well as its efficacy and prognosis. The sensitivity and accuracy of AFP detected by radioimmunoelectron-electrophoresis autoradiography (radio rocketelectrophoresis) method is not as good as that of radioimmunoassay, but the former does not require special radioactivity measurement instruments, which is easy to popularize.
