UROBILINOGEN Bulk QUANTITIES from 10-1000 gram single lot sizes. Custom Fills for Uroblinogen available.
Urobilinigen is used in urine tests. Urine Test Strip: Chemical Principle: Modified Ehrlich’s reaction. Urobilinogen present reacts with Ehrlich’s reagent to form a red-colored compound. Color changes from light orange-pink to dark pink
The test is based on a diazotisation reaction of 4- Methoxybenzene diazoniurn salt and urinary urobilinogen in a strong acid medium. The color changes from pink to brown-red.
Urobilinogen SPECIAL PRECAUTIONS: Air and light sensitive. Keep urobilinogen container tightly closed. Store urobilinogen solution under argon. Minimize urobilinogen exposure to air and light.
Urobilinogen recovery 1 ml added to 100 mls Argonated water at a minimum of 8 mg/dl Urobilinogen by BMD Dipstick Assay
Urobilinogen: 2% substance in 2.6% NaOH
pH Value: 11.8
What is Urobilinogen:
Urobilinogen is a bile pigment that is produced by the degradation of conjugated bilirubin in the biliary tree and small intestine. It is water soluble and colourless.Urobilinogen has several fates:partial oxidation to urobilin partial reabsoption in the small intestine and recirculation back to the liver - enterohepatic circulation reabsorption into blood and passage to kidney for excretion.Urobilinogen is present in the urine of normal subjects. If there is an increase in urobilinogen in the urine then this indicates hepato-cellular dysfunction or an increased bilirubin formation, e.g. due to haemolysis. In intrahepatic obstruction there is no urobilinogen in the urine.Urobilinogen online REF: http://www.gpnotebook.co.uk/cache/-1348861910.htm /Uroblinogen/urinalysis.
UROBILINOGEN RESEARCH: Urobilinogen is a colourless product of bilirubin reduction. Urobilinogen results from the further breakdown of bilirubin in the intestine, which occurs in the presence of bacteria. When levels of urobilinogen become detectable in the urine, it may signify a severe infection, liver damage, or hemolytic anemia. Absent urobilinogen or altered urobilinogen levels can indicate hepatic damage or dysfunction. Increased urine urobilinogen levels may indicate hemolysis of red blood cells
