    Serum alpha-fetoprotein (AFP) levels can help diagnose liver diseases. Elevated AFP is common in acute viral hepatitis and primary liver cell carcinoma, but very high levels are specific to hepatoma and acute viral hepatitis.

    Area of Science:

    • Hepatology
    • Clinical Chemistry

    Background:

    • Alpha-fetoprotein (AFP) is a protein produced during fetal development.
    • Elevated AFP levels in adults can indicate certain liver conditions, including cancer.

    Purpose of the Study:

    • To investigate the diagnostic utility of serum AFP levels in various liver diseases.
    • To differentiate between hepatoma, chronic active hepatitis, alcoholic cirrhosis, and acute viral hepatitis using AFP concentrations.

    Main Methods:

    • Radioimmunoassay was used to measure serum AFP concentrations.
    • 98 patients with diagnosed liver conditions were included in the study.

    Main Results:

    • Raised AFP levels (>30 ng/ml) were detected in 87% of acute viral hepatitis cases, 82% of primary liver cell carcinoma (hepatoma) cases, 58% of chronic active hepatitis cases, and 14% of alcoholic cirrhosis cases.

  • Serum AFP levels exceeding 1,000 ng/ml were exclusively observed in patients with hepatoma and acute viral hepatitis.
  • Conclusions:

    • Serum AFP measurement is a valuable biomarker for diagnosing and differentiating liver diseases.
    • Very high AFP levels (>1,000 ng/ml) are highly suggestive of hepatoma or acute viral hepatitis.
