| 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, 1979] | ||

| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Amnio fld = Amniotic fluid | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}.
