| 11. | In liver disease ( such as hepatitis ), the intrahepatic urobilinogen cycle is inhibited also increasing urobilinogen levels.
|
| 12. | In liver disease ( such as hepatitis ), the intrahepatic urobilinogen cycle is inhibited also increasing urobilinogen levels.
|
| 13. | The urobilinogen in the intestine is directly reduced to brown stercobilin, which gives the feces their characteristic color.
|
| 14. | With limited urobilinogen available for reabsorption and excretion, the amount of urobilin found in the urine is low.
|
| 15. | Specifically, urobilinogen can be reduced to form mesobilirubinogen, and mesobilirubinogen can be further reduced to form stercobilinogen.
|
| 16. | In jaundice secondary to hemolysis, the increased production of bilirubin leads to the increased production of urine-urobilinogen.
|
| 17. | "' Stercobilinogen "'( fecal urobilinogen ) is a chemical created by bacteria in the gut.
|
| 18. | If a urine sample is left to oxidize in air to form urobilin the reagent will not detect the urobilinogen.
|
| 19. | Poorly stored samples can yield false negative results as the urobilinogen suffers photo oxidation to urobilin that does not react.
|
| 20. | Aside from studying creatinine, he is also known for discovering urobilin and urobilinogen in urine and found that these compounds originated in bile.
