    Area of Science:

    • Biochemistry
    • Clinical Chemistry

    Background:

    • Accurate measurement of total blood lipids is crucial for diagnosing and managing various health conditions.
    • Existing methods for blood lipid analysis can be time-consuming or require specialized equipment.

    Purpose of the Study:

    • To develop a fast and simple assay for determining total blood lipid concentration.
    • To provide a cost-effective and accessible method for routine lipid analysis.

    Main Methods:

    • Blood proteins are precipitated using methanol.
    • Lipids are subsequently extracted into diethyl ether.
    • The concentration of extracted lipids is determined by measuring the change in refractive index using a refractometer.

    Main Results:

    • The developed method allows for rapid quantification of total blood lipids.
    • The technique is straightforward and does not require complex instrumentation.

    Conclusions:

    • This novel method offers a simple and efficient approach for total blood lipid assay.
    • The refractometric measurement provides a reliable indicator of lipid levels in blood samples.
