urobilinogen การใช้

• Urobilinogen is converted to the yellow pigmented urobilin apparent in urine.
• I was surfing about the encyclopaedia and landed on the urobilinogen article.
• This constitutes the normal " enterohepatic urobilinogen cycle ".
• Any deterioration in liver function reduces its ability to process the recirculated urobilinogen.
• Intestinal bacteria convert the bilirubin into urobilinogen.
• From here urobilinogen can take two pathways.
• Increased amounts of bilirubin are formed in hemolysis, which generates increased urobilinogen in the gut.
• The degree of color change is proportional to the amount of urobilinogen in the urine sample.
• Formed an unconjugated bilirubin entering the intestine, gives a large number of stercobilinogen ( urobilinogen ).
• In biliary obstruction, below-normal amounts of conjugated bilirubin reach the intestine for conversion to urobilinogen.
• In liver disease ( such as hepatitis ), the intrahepatic urobilinogen cycle is inhibited also increasing urobilinogen levels.
• In liver disease ( such as hepatitis ), the intrahepatic urobilinogen cycle is inhibited also increasing urobilinogen levels.
• The urobilinogen in the intestine is directly reduced to brown stercobilin, which gives the feces their characteristic color.
• With limited urobilinogen available for reabsorption and excretion, the amount of urobilin found in the urine is low.
• Specifically, urobilinogen can be reduced to form mesobilirubinogen, and mesobilirubinogen can be further reduced to form stercobilinogen.
• In jaundice secondary to hemolysis, the increased production of bilirubin leads to the increased production of urine-urobilinogen.
• "' Stercobilinogen "'( fecal urobilinogen ) is a chemical created by bacteria in the gut.
• If a urine sample is left to oxidize in air to form urobilin the reagent will not detect the urobilinogen.
• Poorly stored samples can yield false negative results as the urobilinogen suffers photo oxidation to urobilin that does not react.
• Aside from studying creatinine, he is also known for discovering urobilin and urobilinogen in urine and found that these compounds originated in bile.
