For a patient suspected of hepatic conditions, which laboratory value would be most beneficial to evaluate?

• A. Hematocrit
• B. Indirect bilirubin
• C. White blood count
• D. Alpha-feto protein

Answer: (B)

Bilirubin processing by the liver shows how well conjugation occurs. Indirect (unconjugated) bilirubin rises when the liver’s ability to conjugate bilirubin is impaired, which is a common issue in hepatic dysfunction. Measuring indirect bilirubin specifically helps assess the liver’s conjugation capacity and distinguishes hepatic concerns from other causes of jaundice, such as biliary obstruction (which elevates direct bilirubin) or purely hemolytic processes. The other options don’t provide as direct a read on hepatic processing: hematocrit isn’t a liver function marker; white blood cell count reflects inflammation or infection rather than hepatic processing; and alpha-fetoprotein is a tumor marker more relevant to hepatocellular carcinoma risk rather than general hepatic evaluation.
