    Area of Science:

    • Biochemistry
    • Clinical Chemistry
    • Analytical Chemistry

    Background:

    • Accurate assessment of fetal pulmonary maturity is crucial for optimizing perinatal care and reducing neonatal complications.
    • Amniotic fluid phospholipid profiles offer valuable insights into fetal lung development.
    • Existing methods for phospholipid analysis may lack the simplicity and reliability required for routine clinical practice.

    Purpose of the Study:

    • To develop and validate a straightforward and dependable High-Performance Thin-Layer Chromatography (HPTLC) method for the individual determination of nine key phospholipids in amniotic fluid.
    • To establish a standardized protocol for clinical laboratory application.
    • To explore the utility of this method in assessing fetal pulmonary maturity via specific phospholipid ratios.

    Main Methods:

    Related Experiment Videos

    • High-Performance Thin-Layer Chromatography (HPTLC) was employed for the separation and quantification of phospholipids.
    • Standard phospholipids were utilized for method standardization.
    • The method was optimized considering practical aspects for clinical settings, including reagents and solvents.
    • The developed HPTLC method was validated using 34 amniotic fluid samples.

    Main Results:

    • The HPTLC method successfully enabled the individual determination of nine phospholipids: lysophosphatidylcholine, sphingomyelin, phosphatidylcholine, phosphatidylinositol, phosphatidylserine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidic acid, and cardiolipin.
    • The method demonstrated reliability and simplicity, suitable for clinical practice.
    • Analysis of phospholipid ratios in amniotic fluid samples was feasible using this technique.

    Conclusions:

    • The developed HPTLC method provides a reliable and practical approach for quantifying multiple phospholipids in amniotic fluid.
    • This method holds significant potential for routine clinical use in evaluating fetal pulmonary maturity.
    • The ability to determine specific phospholipid ratios offers a valuable tool for obstetric and neonatal care decisions.
