The L/S ratio (lecithin/sphingomyelin) is a test used to assess fetal lung maturity. A ratio of 2:1 or greater is generally considered indicative of mature fetal lungs, suggesting that the fetus is less likely to suffer from respiratory distress syndrome if born at this time. This ratio typically reaches 2:1 or greater by about 35 weeks of gestation in most pregnancies.
