Answer

Laboratory findings associated with particular disease etiologies include the following:

  • Hepatitis B surface antigen (HBsAg)/hepatitis B core antibody (anti-HBc), anti-HCV - Viral hepatitis (current/past)
  • Increased iron saturation (> 50%) - Underlying hemochromatosis
  • Low α1-antitrypsin levels - α1-Antitrypsin deficiency
  • Increased AFP - Levels higher than 400 ng/mL are considered diagnostic with appropriate imaging studies
  • Hypercalcemia - Ectopic parathyroid hormone production is possible in 5-10% of patients with HCC
