NettetThe lecithin-to-sphingomyelin ratio is calculated. The clinical significance of this number is discussed. Since this is a procedure that is often performed in medical laboratories, most of the supplies and materials for the experiment are commercially available in kit form. Keywords: Lecithin, sphingomyelin, TLC, clinical chemistry. Nettet1. jan. 1983 · Abstract. Amniotic fluid phospholipids (lecithin, sphingomyelin, phosphatidylglycerol) were extracted and separated by the method of Gluck and associates. 10,11 In addition, these lipids were quantified against standards that were concurrently developed in three adjacent thin layer chromatography (TLC) channels. A …

NettetThe significance of the lecithin sphingomyelin (L:S) ratio as a determining factor in fetal lung maturity is well established. An L:S ratio of greater than 2.0 to 2.5 is indicative of fetal lung maturity in most assays. The fluorescence polarization method (fluorescence polarization less than 0.320) has been associated with fetal lung maturity. NettetLecithin/sphingomyelin (L/S) ratio was measured and rapid surfactant test (RST) was performed on amniotic fluid samples drawn from 60 normal and 18 diabetic pregnancies, for determination of fetal lung maturity. The results were compared to the neonatal outcome. Comparison of L/S ratio and RST demon …

The L/S ratio describes the relative change in the concentration of lecithin to that of sphingomyelin in the AF. The greater the L/S ratio, the more mature the fetal lungs are. marissa gilbert accenturemarissa ginocchiNettetLecithin/sphingomyelin (L/S) ratio was measured and rapid surfactant test (RST) was performed on amniotic fluid samples drawn from 60 normal and 18 diabetic … daniel conahan updateNettetTest results are given as a ratio of lecithin to sphingomyelin. The range of results are: A ratio of less than 1.5:1. This means that your baby's lungs are immature. If born now, your baby may have breathing problems. A ratio between 1.5:1 and 1.9:1.
