Reagents, Clinical Chemistry, Lipid, Lecithin/Sphingomyelin Ratio
Definition : Clinical chemistry reagents intended to perform quantitative chemical analyses of body fluids (typically amniotic fluid) to determine the ratio of lipid lecithin (phosphatidylcholine) to sphingomyelin (L/S ratio). Sphingomyelin is a lipid derived from nonlung sources that is used as a marker against which lecithin is measured. An L/S ratio of 2.0 or greater in an amniotic fluid sample is considered a measure of fetus lung maturity.
