埃赛平板(EISAI Plate)法是根据单向免疫扩散原理制成的一种用以测定原发性肝癌病人血清中甲胎蛋白含量的方法。此免疫板含有高低两种不同液度的兔抗人 AFP 血清,其定量检测范围在2～300mg/dl 之间。本文对原发性肝癌30例,消化道及肺癌9例,肝炎、肝硬化5例和正常人6例作了血清中 AFP 的测定。30例肝癌病人中28例(93％)阳性,其它疾病和正常人均为阴性。埃赛免疫板对原发性肝癌的诊断结果准确,操作简便。由于本免疫板检测 AFP 量的范围较大,故可进行动态观察。
The EISAI Plate method is a method based on the principle of one-way immunodiffusion to determine the alpha-fetoprotein content in the serum of patients with primary liver cancer. The immune plate contains rabbit anti-human AFP serum with two different liquid levels. The quantitative detection range is between 2 and 300 mg/dl. In this paper, serum AFP was measured in 30 cases of primary liver cancer, 9 cases of digestive tract and lung cancer, 5 cases of hepatitis, liver cirrhosis and 6 cases of normal persons. Twenty-eight patients (93%) were positive in 30 patients with liver cancer. Other diseases and normal persons were negative. The diagnostic results of the ESA immune plate for primary liver cancer are accurate and easy to operate. Due to the large range of AFP detection by this immune plate, dynamic observation can be performed.
