LOINC long common name : Phosphatidylcholine.saturated [Moles/volume] in Amniotic fluid;
LOINC short name : PC Satd Amn-sCnc;
LOINC description : An increased concentration of amniotic fluid saturated phosphatidylcholine (SPC),
which is the major component of pulmonary surfactant, correlates with fetal lung maturity
and is used to predict fetal respiratory distress syndrome. SPC may be a more specific
and sensitive predictor than the lecithin/sphingomyelin ratio. [N Engl J Med 301:1013-1018,
