    Area of Science:

    • Clinical Chemistry
    • Analytical Chemistry

    Background:

    • Accurate creatinine measurement is crucial for assessing kidney function.
    • Multiple analytical methods exist for serum and urine creatinine determination.

    Purpose of the Study:

    • To evaluate the performance of the Beckman Creatinine Analyzer.
    • To compare its results against the GEMSAEC Centrifugal Analyzer and a manual method.

    Main Methods:

    • Comparative analysis of creatinine determination in serum and urine.
    • Evaluation of linearity, stability, recovery, and precision.
    • Assessment of interference from common biological substances.

    Main Results:

    • The Beckman Creatinine Analyzer demonstrated comparable results to the GEMSAEC and manual methods.
    • Negligible interference was observed from bilirubin, protein, lipemia, uric acid, and hemolysis.
    • Significant interference was identified with acetone and acetoacetate.

    Conclusions:

    • The Beckman Creatinine Analyzer is a reliable tool for creatinine measurement.
    • Potential interference from ketones (acetone, acetoacetate) should be considered during analysis.
