A good correlation between the amniotic fluid surface tension and gestational age was found in 51 amniotic fluid samples from normal pregnancies. The samples were obtained between the 20th and 43rd week of gestation. A good relation also exists between amniotic fluid lecithin concentration and fluid surface tension, and between said surface tension and the foam test carried out according to Clements et al. (4).
在51份来自正常妊娠的羊水样本中，发现羊水表面张力与孕周之间存在良好的相关性。这些样本是在妊娠第20至43周期间采集的。羊水卵磷脂浓度与液体表面张力之间，以及所述表面张力与根据克莱门茨等人（4）进行的泡沫试验之间也存在良好的关系。
