Which parameter is used to evaluate liver function through bile acids measurements?

• A. Amylase
• B. Bile acids
• C. Creatinine
• D. Glucose

Answer: (B)

Measuring bile acids directly assesses how well the liver can process and excrete them. Bile acids are produced in the liver, conjugated, and secreted into bile, then reabsorbed in the intestine; when liver function is impaired or bile flow is blocked (cholestasis), these acids spill into the blood. Elevated serum bile acids reflect reduced hepatic excretory capacity and are a functional marker of liver health, making this parameter the best choice for evaluating liver function through bile acid measurements. Other options point to different organ systems or general metabolism (amylase for the pancreas, creatinine for kidney function, glucose influenced by multiple processes) and do not specifically gauge liver excretory function via bile acids. In practice, bile acid testing, often with fasting and postprandial samples, helps detect hepatic dysfunction and biliary disease.
