We assessed several modifications of thin-layer chromatography for evaluation of amniotic fluid lecithin/sphingomyelin ratios. For a procedure which is reliable, economical, and easy to perform, we preferred laboratory-prepared plates using SI-LICAR TLC-7GF. For spot detection, we preferred the iodine vapor method.
