    Area of Science:

    • Biochemistry
    • Clinical Chemistry
    • Analytical Chemistry

    Background:

    • Hyperprolinemia is a rare metabolic disorder characterized by elevated proline levels.
    • Accurate quantification of serum proline is crucial for diagnosing and managing hyperprolinemia.

    Purpose of the Study:

    • To describe a reliable method for determining serum proline concentrations.
    • To validate the method's suitability for clinical application in hyperprolinemia diagnosis.

    Main Methods:

    • Serum samples undergo protein precipitation using the Folin-Wu method.
    • Proline is quantified via colorimetric analysis using isatin.
    • The resulting color complex is extracted with methylene chloride.
    • Absorbance is measured at 600 nm to determine proline levels.
