The results obtained for amniotic fluid lecithin/sphingomyelin ratios are method-dependent. Some of the method variables which affect the assay are the presence of blood or meconium, the conditions of centrifugation, the spray reagent used for visualization following thin layer chromatography, and variations in the techniques used for quantitation of the spots. Control of these variables is necessary if the results are to be reliable and useful.
羊水卵磷脂/鞘磷脂比值的检测结果取决于检测方法。影响该检测的一些方法变量包括血液或胎粪的存在、离心条件、薄层色谱后用于显色的喷雾试剂以及斑点定量技术的差异。如果结果要可靠且有用,就必须控制这些变量。
