The butterfat absorption test in adults.

H Chaun, M A Mullinger, P Solvonuk

    The American Journal of Digestive Diseases
    |October 1, 1975
    PubMed
    Summary

    The butterfat absorption test effectively identifies fat malabsorption in adults. A low serum optical density after butterfat ingestion indicates poor fat absorption, aiding in diagnosing steatorrhea.

    Area of Science:

    • Gastroenterology
    • Clinical Diagnostics

    Background:

    • Fat malabsorption, or steatorrhea, affects nutrient absorption and can be linked to various gastrointestinal disorders.
    • Accurate and accessible diagnostic methods are crucial for timely intervention.

    Purpose of the Study:

    • To evaluate the diagnostic utility of the butterfat absorption test in adult patients with suspected fat malabsorption.

    Main Methods:

    • The study involved 89 adult patients.
    • Serum optical density was measured after butterfat ingestion.
    • Results were correlated with fat balance studies to confirm steatorrhea.

    Main Results:

    • Out of 42 patients with confirmed steatorrhea, 33 (78.6%) showed abnormally low serum optical density.
    • Excluding 8 unexplainable cases, 28 of 34 patients (82.4%) exhibited an abnormal response.
    • A maximum optical density increase of ≤0.25 reliably indicated fat malabsorption.

    Conclusions:

    • The butterfat absorption test is a valuable tool for diagnosing fat malabsorption in adult patients.
    • Abnormal serum optical density responses following butterfat ingestion are indicative of steatorrhea.
