Positive correlation of optical density at 650 nm. with lecithin/sphingomyelin ratios in amniotic fluid
In this study, we have attempted to correlate optical density measurements of amniotic fluids with L/S ratios. We may conclude, with over a 98 per cent accuracy, that fluids having optical density readings of 0.15 and above, at 650 nm. will have an L/S ratio over 2.0. Fluids having optical density r...
