作者自1979年6月～1980年12月测定母血清甲胎蛋白(AFP)569次,羊水101次,脐血清38次。本组采用放射火箭电泳自显影法,最低敏感度25毫微克/毫升。测定结果:正常妊娠母血清 AFP值于妊娠 11周开始上升,均值30.90毫微克/毫升,31～34周达高峰,均值104.70毫微克/毫升,以后递减,足月时均值70.39毫微克/毫升,产后第三天下降至33.37毫微克/
The authors measured 569 maternal serum alpha-fetoprotein (AFP), 101 amniotic fluid and 38 umbilical serum from June 1979 to December 1980. This group using rocket electrophoresis autoradiography, the lowest sensitivity of 25 ng / ml. The results showed that the normal pregnancy serum AFP value increased from the 11th week of gestation to the average of 30.90 ng / ml and peaked from 31 to 34 weeks, with an average value of 104.70 ng / ml, then declining, with a mean of 70.39 ng / The third day after delivery decreased to 33.37 ng /
