Liver function tests may be useful in narrowing the differential diagnosis. Hepatocellular enzyme and alkaline phosphatase levels may be elevated. None of these tests are specific for the diagnosis of a choledochal cyst.

Serum amylase and lipase concentrations may be increased in the presence of pancreatitis. Serum amylase concentrations also may be elevated in biliary obstruction and cholangitis.
