To evaluate suspected biliary cirrhosis, which initial set of tests is most appropriate to order?

• A. Liver biopsy alone
• B. LFTs, alkaline phosphatase, and antimitochondrial antibodies
• C. Abdominal ultrasound alone
• D. Serum amylase and lipase

Answer: (B)

When biliary cirrhosis is suspected, begin with tests that reveal a cholestatic pattern and a biliary-specific serology. Elevated alkaline phosphatase and bilirubin on liver function tests indicate cholestasis, and antimitochondrial antibodies are characteristic of primary biliary cholangitis, the biliary-related cause of cirrhosis. This combination helps confirm the biliary etiology early. A liver biopsy is not needed initially; it’s reserved for diagnostic uncertainty or to stage fibrosis once the diagnosis is established. Abdominal ultrasound can show biliary obstruction or structural issues but cannot diagnose biliary cirrhosis on its own. Serum amylase and lipase target pancreatic disease and aren’t helpful in evaluating biliary cirrhosis.
