人绒毛膜促性腺激素(HCG)是由合体滋养细胞分泌的糖蛋白激素,由α、β亚基组成,HCGα亚基抗体与卵泡刺激素(FSH)、黄体生成素(LH)、TSHα亚基均能发生交叉反应,而HCGβ亚基片段为其所特有而不受LH干扰,因此临床利用HCGβ亚基的特异抗血清,测定母体血清中HCGβ亚基,现已采用β-H
Human chorionic gonadotropin (HCG) is a glycoprotein hormone secreted by syncytiotrophoblasts. It consists of α and β subunits. HCG α subunit antibody interacts with follicle stimulating hormone (FSH), luteinizing hormone (LH), TSHα subunit Can cross-react, while the HCGβ subunit fragment is unique to its own without LH interference, so the clinical use of HCGβ subunit specific antiserum, determination of HCGβ maternal serum subunit has been used β-H
