WebIn a study of 766 amniotic fluids, collected from pregnancies between 26 weeks and term, phosphatidylglycerol (PG) was identified in a greater proportion than was a mature lecithin/sphingomyelin (L/S) ratio at all gestational ages between 28 and 38 weeks regardless of the underlying pregnancy complication. WebB. Phosphatidyl Glycerol The presence of phosphatidyl glycerol in excess of 3% (i.e., a positive test) indicates functional lung maturity and is a more reliable predictor of lung maturity than the L:S ratio in clinical situations in which the L:S may be falsely mature, such as maternal diabetes.
