It is suspected based on laboratory testing demonstrating direct hyperbilirubinemia, elevated alkaline phosphatase, and gamma-glutamyl transferase.Biliary atresia is progressive inflammatory, fibrosing cholangiopathy. Ultrasonography cannot distinguish the obliterated extrahepatic biliary ducts, but can suggest the diagnosis if there is an absent or diminuitive gallbladder or a triangular cord sign.Ultimately, cholangiography is the gold standard for confirming the diagnosis of biliary atresia.
