Abstract
A test that circumvents the complex methodology needed for the determination of L/S ratios has been developed. It has been observed that the optical density, measured at 400 nm, of supernatants collected from fresh amniotic fluids centrifuged at 2000 g for 10 minutes correlates with L/S ratios.
摘要
一种无需采用测定卵磷脂/鞘磷脂（L/S）比值所需复杂方法的检测方法已被开发出来。据观察，对以2000g离心10分钟的新鲜羊水收集的上清液在400nm处测得的光密度与L/S比值相关。
