[Serum phospholipids determination by an automatic enzymatic method (author's transl)]

F Tallet, D Raichvarg, J Canal

    Annales De Biologie Clinique
    |January 1, 1980
    PubMed
    Summary

    This study introduces an automatic enzymatic method (AEM) for serum phospholipids determination, showing acceptable correlation with chemical and manual methods. The AEM offers good precision and minimal contamination for reliable lipid analysis.

    Area of Science:

    • Biochemistry
    • Clinical Chemistry
    • Analytical Chemistry

    Context:

    • Serum phospholipids are crucial biomarkers in clinical diagnostics.
    • Existing methods for phospholipids determination include classical chemical and manual enzymatic methods.
    • There is a need for automated, precise, and reliable methods for serum phospholipids analysis.

    Purpose:

    • To evaluate the efficacy of an automatic enzymatic method (AEM) for serum phospholipids determination.
    • To compare the AEM with the classical chemical method and the manual enzymatic method (MEM).
    • To assess the precision, accuracy, and potential interferences of the AEM.

    Summary:

    • The study compared an automatic enzymatic method (AEM) with classical chemical and manual enzymatic methods (MEM) using 100 serum samples.

  • The AEM demonstrated acceptable correlation coefficients, good precision, and negligible contamination.
  • The calibration curve was linear up to 5 mmol/l, with no interference from triglycerides, cholesterol, glucose, or high uric acid levels. However, hemolysis and high bilirubin concentrations affected the results.

    • Impact:

    • The AEM provides a reliable and automated alternative for serum phospholipids measurement.
    • This method can improve the efficiency and accuracy of lipid profiling in clinical laboratories.
    • Understanding interferences like hemolysis and bilirubin is crucial for accurate clinical interpretation of phospholipid levels.
