Early diagnosis is crucial for better outcomes. Initial screenings include blood tests to check liver function, and ultrasound to visualize the liver and bile ducts. If these tests indicate possible biliary atresia, a more definitive diagnostic procedure called a liver biopsy may be performed. This involves taking a small sample of liver tissue to check for signs of bile duct obstruction and liver damage. Additionally, a cholangiogram, which involves injecting a dye into the bile ducts and taking X-rays, can confirm the diagnosis.
