人类绒毛膜促性腺激素(HCG)是孕卵着床后合胞体滋养叶细胞分泌的一种糖蛋白激素,早于1927年在孕妇的尿和血中均已发现,具有促性腺功能,使未成熟的动物早热。临床上根据尿和血中HCG的含量来进行妊娠及滋叶细胞肿瘤的诊断已有50多年,由于生物学检定法及半定量的被动血凝抑制反应法,灵敏度低,操作复杂,Bagshawe等首先建立HCG的放射免疫测定法,其优点灵敏度高,特异性 Human chorionic gonadotropin (HCG) is a glycoprotein hormone secreted by syncytiotrophoblast cells after the implantation of the ovum. As early as 1927, it has been found in urine and blood of pregnant women that it has gonadal function, Mature animals are hot early. Clinically based on urinary and blood levels of HCG to pregnancy and tumor diagnosis of tumor cells have more than 50 years, due to biological assay and semi-quantitative passive hemagglutination inhibition reaction method, low sensitivity, complex operation, Bagshawe other first The establishment of radioimmunoassay of HCG, its advantages of high sensitivity and specificity
