fetal lung maturity assessment
Prenatal testing to evaluate fetal pulmonary development and readiness for extrauterine life.
Full Definition
A comprehensive evaluation of fetal lung development typically performed in the third trimester to determine the risk of respiratory distress syndrome if delivery occurs. The assessment involves multiple biochemical and biophysical markers obtained through amniocentesis, including surfactant proteins, phospholipid ratios, and lamellar body counts. This testing is crucial for timing elective deliveries and counseling patients about neonatal respiratory outcomes. Results guide clinical decision-making regarding corticosteroid administration and delivery planning in cases of preterm labor or medically indicated early delivery.
Usage
Usage note: Often abbreviated as FLM assessment in clinical documentation; distinguish from general lung development monitoring.
