Final answer:
Bilirubinuria does not always indicate liver disease. It can be caused by various conditions, including genetic disorders and biliary tree obstruction.
Step-by-step explanation:
No, bilirubinuria does not ALWAYS indicate liver disease. Bilirubinuria is the presence of bilirubin in the urine, which can occur due to liver diseases, but it can also be caused by other factors. Increased levels of bilirubin in the system can be a result of various conditions, including certain genetic disorders, biliary tree obstruction, or hepatic (parenchymatous) jaundice caused by damage to the liver cells. It is important to consult a healthcare professional for diagnosis and further evaluation.
