A COMPARISON OF LABORATORY TESTS IN THE MALABSORPTION SYNDROME.

C HETENYI, P M O'SULLIVAN

    Canadian Medical Association Journal
    |January 18, 1964
    PubMed
    Summary

    The radioiodinated triolein absorption test accurately diagnoses malabsorption, correlating well with fecal fat excretion. Combining it with the urinary xylose test offers a reliable screening method for digestive disorders.

    Area of Science:

    • Gastroenterology
    • Diagnostic Imaging
    • Clinical Chemistry

    Background:

    • Malabsorption syndromes present diagnostic challenges.
    • Accurate assessment of fat absorption is crucial for diagnosing gastrointestinal disorders.

    Purpose of the Study:

    • To evaluate the diagnostic utility of the radioiodinated triolein absorption test.
    • To compare its efficacy against the urinary xylose excretion test.
    • To assess the combined diagnostic value of both tests.

    Main Methods:

    • Radioiodinated triolein absorption test performed on 93 individuals.
    • Comparison with fecal radioactivity and fecal fat excretion measurements.
    • Urinary xylose excretion test performed on 96 individuals.
    • Comparative analysis of both tests in 78 cases.

    Main Results:

    • A significant correlation was observed between radioiodinated triolein absorption and fecal fat excretion.
    • Both tests showed diagnostic value in non-tropical sprue.
    • Radioiodinated triolein test was superior for post-bowel resection malabsorption.
    • Urinary xylose test was more sensitive to treatment response and post-gastrectomy malabsorption.
    • Simultaneous use of both tests proved a reliable screening procedure.

    Conclusions:

    • The radioiodinated triolein absorption test is a reliable method for diagnosing malabsorption.
    • The urinary xylose excretion test effectively monitors treatment response.
    • Combined application of both tests enhances diagnostic accuracy and reliability for screening malabsorption syndromes.
