Phosphatidylglycerol fetal lung maturity
WebThis test measures the level of phosphatidylglycerol in amniotic fluid. This test is used to evaluate and manage the lung maturity, or how well-developed the lungs are, of an unborn baby [1]. This test may also be used in high risk pregnancies to help predict if an unborn baby's lungs are mature before the baby is born [2] [1] [3]. WebLBC of ≥50,000/µL generally suggest maturity; however, cutoffs are instrument-specific. Currently, there is no standardized QC material, and LBC cannot be performed on blood or meconium-contaminated AF. Validation of LBC cutoffs is challenging, given the low incidence of RDS.

WebMay 8, 2024 · Phosphatidylcholine, also referred to as lecithin, is one of the phospholipids present in mature surfactant. It is stored and secreted by organelles called lamellar bodies. These organelles appear after 22 to 24 weeks gestation. Before the 28th week of gestation, the fetal lung primarily synthesizes sphingomyelin, a nonpulmonary lipid. WebSep 15, 1982 · Phosphatidylglycerol (PG) is present only in amniotic fluid and respiratory tract effluent. PG may characterize surfactant maturity in samples of amniotic fluid …
WebPhosphatidylcholine, a type of phospholipid in lecithin. The lecithin–sphingomyelin ratio (a.k.a. L-S or L/S ratio) is a test of fetal amniotic fluid to assess for fetal lung immaturity. … WebPhosphatidylglycerol, commonly abbreviated as PG, accounts for approximately 5-15% of the phospholipids present in the surfactant. PG appears in the fetal lung at 36 weeks …

WebAn L/S ratio less than 2:1 and absence of phosphatidylglycerol at term indicate fetal lung immaturity and possible respiratory distress syndrome. Other conditions that decrease production of surfactants include advanced maternal age, multiple gestation, and polyhydramnios.
