    This study found that specific transformations of Bromosulphalein (BSP) tests correlate with liver excretory capacity. These findings offer a more physiological way to assess liver function decline in chronic liver disease.

    Area of Science:

    • Hepatology
    • Clinical Chemistry
    • Biostatistics

    Background:

    • Chronic liver damage impairs hepatic excretory function.
    • Bromosulphalein (BSP) tests are used to assess liver function.
    • Existing BSP test analyses may lack physiological relevance.

    Purpose of the Study:

    • To statistically compare different Bromosulphalein (BSP) tests.
    • To correlate BSP test results with the maximal excretory capacity of the liver (BSP Tm).
    • To establish a more physiologically meaningful assessment of hepatic functional deterioration.

    Main Methods:

    • Statistical comparison of various BSP tests in normal subjects and patients with chronic liver damage.
    • Linear correlation analysis between logarithm of BSP retention and BSP Tm.

  • Double logarithmic transformation to correlate the second exponential component of BSP plasma disappearance (k(2)) with BSP Tm.

    • Main Results:

    • Only the logarithm of BSP retention showed a linear correlation with BSP Tm.
    • A double logarithmic transformation was necessary to correlate k(2) with BSP Tm.
    • Statistical relationships were established to express hepatic functional deterioration.

    Conclusions:

    • Logarithmic transformations of BSP test data provide a more physiologically relevant measure of liver function.
    • These statistical relationships can quantify hepatic functional deterioration in chronic liver disease.
    • Careful consideration of method limitations is crucial for accurate interpretation.
