产前诊断是近年来医学上重大的进展之一。自1976—1978年间进行了下列实验:应用简易羊水细胞培养法,对300例正常羊水细胞培养,成功率达90％;190例正常羊水甲胎蛋白(AFP)含量的放射免疫火箭电泳法测定,测得AFP正常值的标准曲线;50例正常羊水细胞性染色质测定,预测的准确性为98％;20例适应症病例的产前诊断结果,可分为三个组: Prenatal diagnosis is one of the major advances in medicine in recent years. From 1976 to 1978, the following experiments were carried out: The simple amniotic fluid cell culture method was used to culture 300 normal amniotic fluid cells with a success rate of 90%; the radioimmunoassay of 190 normal amniotic fluid AFPs was performed, Measured normal AFP curve; 50 cases of normal amniotic fluid chromatin qualitative determination of the accuracy of 98%; 20 cases of indications for prenatal diagnosis can be divided into three groups:
