Question

Quizplus · Accepted Answer

In obstructive liver disease, the bile ducts are blocked, preventing bile (and thus bilirubin) from reaching the intestines. This results in decreased fecal urobilinogen (since bilirubin is not reaching the intestines to be converted into urobilinogen), positive urine bilirubin (as conjugated bilirubin is excreted in the urine due to the blockage), and increased serum conjugated bilirubin (since it cannot be excreted into the intestines).
