Ehrlich's reagent is also used as a stain in thin layer chromatography and as a reagent to detect urobilinogen in fresh, cool urine.
22.
The liver conjugates bilirubin, making it water-soluble; and the conjugated form is then excreted in urine as urobilinogen, giving urine its color.
23.
In this case, presence of bilirubin ( conjugated ) in the urine without urine-urobilinogen suggests obstructive jaundice, either intra-hepatic or post-hepatic.
24.
There, colonic bacteria deconjugate and metabolize the bilirubin into colorless urobilinogen, which can be oxidized to form urobilin and stercobilin : these give stool its characteristic brown color.
25.
Low urine urobilinogen levels may result from congenital enzymatic jaundice ( hyperbilirubinemia syndromes ) or from treatment with drugs that acidify urine, such as ammonium chloride or ascorbic acid.
26.
Urobilinogen ( aka D-urobilinogen ) is closely related to two other compounds : mesobilirubinogen ( aka I-urobilinogen ) and stercobilinogen ( aka L-urobilinogen ).

30.
In early liver disease, impaired biliary excretion causes sterocobilinogen to be absorbed mostly by the kidney, and, therefore, stercobilinogen will appear in the urine in excess as urobilinogen.
