A young baby underwent a liver function test, and the report showed elevated levels of total bilirubin, direct bilirubin, and indirect bilirubin. Other indicators such as albumin, globulin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and glutaminase were also abnormal. Parents are worried that the baby may have hepatitis, and the doctor recommends further examination to determine the cause and provide treatment.
