Which biomarker has been described as being conjugated by the liver for digestive use?

• A. HCG
• B. CEA
• C. AFP
• D. CA125

Answer: (A)

The liver conjugates many substances to make them water-soluble for biliary excretion into the digestive tract, a process that helps with digestion and elimination. In the context of the biomarker options, this description is applied to human chorionic gonadotropin. It’s the one described as undergoing hepatic conjugation for digestive use, whereas the other markers—CEA, AFP, and CA125—are tumor markers with different clearance pathways and aren’t typically described as being conjugated by the liver for digestion.
