Estimating Lecithin/Sphingomyelin Area Ratio in Amniotic Fluid
AbstractA knowledge of the pulmonary maturity of the unborn fetus is an important factor in deciding when to induce birth. A lecithin/sphingomyelin area ratio is obtained by thin-layer chromatography. A molybdenum spray is used to make visible only the choline-containing phospholipids, without necessitating the use of heat. This is a quick and easy method which produces reliable results.
