Amniotic fluid surface tension during pregnancy.
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).
