The amniotic fluid lecithin/sphingomyelin (L/S) ratio from 128 cases of high risk pregnancies were measured by using high performance liquid chromatography (HPLC). The L/S ratio was found to be increased in patients with pre-eclampsia, hypertension, intrauterine growth retardation (IUGR), prolonged rupture of membranes (PROM), and twin gestation, but decreased in patients with diabetes from gestational diabetes to class C. In patients with placenta previa, the L/S ratio was not affected.
采用高效液相色谱法（HPLC）测定了128例高危妊娠患者的羊水卵磷脂/鞘磷脂（L/S）比值。结果发现，子痫前期、高血压、胎儿宫内生长受限（IUGR）、胎膜早破（PROM）及双胎妊娠患者的L/S比值升高，而从妊娠期糖尿病到C级糖尿病患者的L/S比值降低。前置胎盘患者的L/S比值不受影响。
