Palmitic acid concentrations and L/S ratios have been estimated in amniotic fluid specimens with and without centrifugation and cold acetone precipitation. Although the number of cases was small, both of these measurements in uncentrifuged fluid seemed to reflect only indirectly on lung maturation in normal pregnancy while with centrifuged fluid the L/S value predicted RDS in one infant more reliably than palmitic acid concentration.
在经过和未经过离心及冷丙酮沉淀处理的羊水样本中，已对棕榈酸浓度和L/S比值进行了估算。尽管病例数量较少，但未离心样本中的这两项测量指标似乎仅间接反映正常妊娠时的肺成熟情况，而对于离心样本，L/S值比棕榈酸浓度更可靠地预测了一名婴儿的呼吸窘迫综合征。
