Urobilinogen in obstructive jaundice is lowered in urine.
Urobilinogen Is produced by intestinal flora from conjugated bilirubin in bile and then it gets reabsorbed into the circulation to appear in urine. So if there is no bile going to the intestines there would be no urobilinogen produced which means no reabsorpion of urobilinogen and consequently lesser urobilinogen in urine.

LOW .. The urobilinogen it's formed by the intestinal Bacterias from bilirubin, so if you have a obstructive jaundice it will never get formed

That's what I thought also. But I was confused after doing Kaplan Qbank, because the explanation said in obstructive jaundice the level of urobilinogen can be normal, raised or lowered. No further explanation.
