Why does urobilinogen increase in the urine?
When bilirubin production increases because of red blood cell destruction (hemolysis) or liver disease, urobilinogen levels rise in the urine. On the other hand, when insufficient bilirubin reaches the gut due to decreased bile flow, urobilinogen production is reduced, resulting in extremely low or absent urinary urobilinogen levels.

What is urobilinogen in urine?
Urobilinogen is formed from the reduction of bilirubin. Urobilinogen is normally present in urine in low concentrations. Urobilinogen is formed in the intestine from conjugated bilirubin, and a portion of it is absorbed back into the blood. Positive urine urobilinogen test results may indicate liver diseases such as viral hepatitis, cirrhosis, ...

If you are a woman, you should tell your health care provider if you are menstruating. Urobilinogen in urine test is only one measure of liver function.
Overview
Causes
- The amount of urobilinogen in urine may increase due to present of hemolytic process, for example hemolytic anemia. Other factors that causes increased amount of this substance may include hepatitis infection or cirrhosis. Low level of urobilinogen in urine may occur due to complete obstructive jaundice. Some treatments that include broad spectrum antibiotics which …
- Low levels of urobilinogen If you find that the levels of urobilinogen in urine are lower in your body, the reason could be intake of antibiotics, which interfere with the flora that lines the walls of the intestines. The drugs that usually cause these, are strong drugs used for antibacterial treatment of jaundice, and probably high doses of ascorbic acid or ammonium chloride.
Symptoms
- You can tell if you are suffering from this condition if you have light colored stools and dark colored urine. Urobilinogen is the one which gives stools their characteristic dark color. When you have this condition you will seem jaundiced since this is an indication of a problem with the liver.
Measurement
- Urobilinogen content is determined by a reaction with Ehrlich's reagent, which contains para-Dimethylaminobenzaldehyde and may be measured in Ehrlich units. Ehrlich's reagent reacts with urobilinogen to give a pink-red color. One Ehrlich unit is equal to one milligram of urobilinogen per deciliter of sample.
Diagnosis
- Excessive break down of red blood cells that cause hemolytic anemia also causes increased level of urobilinogen in urine. Other situations include overburdening of liver, increased production of urobilinogen, restricted functioning of the urine, liver cirrhosis, hepatic infection, etc. Measuring range of urobilinogen is 0 to 8 mg/dl. Normal range off urobilinogen is below 17 umol/l, which le…
- Testing for urobilinogen in urine is important since it shows how well the liver is working. The walls of the intestine produce bilirubin, which is broken down into urobilinogen and flushed out by the kidneys. If a patient gets ill and red blood cells are ruptured, there will be an increase in bilirubin. If the intestine or the liver is infected, then there will be a significant rise in bilirubin. Thi…
Clinical Significance
- Some of this urobilinogen is used by the intestine while some are transferred to the kidney for egestion. Some amount of urobilinogen gets converted to urobilin which is expelled from the body through urine. The amount which is not absorbed by intestine often transforms into stercobilin and is egested through feces. Increased urobilinogen amount in the urine often indicates hyperb…
- High levels of urobilinogen High levels of urobilinogen in urine are alarming since it could mean that the patient has a disease that is interfering with the normal working of the liver. Cancer of the liver, and liver cirrhosis, are some of the diseases that cause this compound to increase in the body, and one should get immediate medical attention.
Treatment
- Once the doctor has ascertained that you are suffering from this condition, he will give you the best treatment for the particular ailment that is causing your liver to fail. The reason why the doctor must use the best option is because the ailment must be contained urgently. If you have low levels of urobilinogen, brought about by treatment of another condition, then he or she may …
Chemistry
- False-Positive reaction of urobilinogen can occur with chemical reagent strip technique in case of presence of substance that may react with Ehrlichs reagent. These substances may include sulfonamide or para-aminosalicyclic acid. Medicine with Azo dyes has gold color that can disguise the reaction leading to false positive reaction.
Prevention
- Similarly, if a disease of the liver is the cause of increased urobilinogen, then the patent must be monitored closely. If your liver is affected to a great extent, the patient should stay in a hospital where he or she will get strong antivirals. In cases where it is too late to save the liver, the patient should look for a liver transplant. By drinking at least 8 glasses of water a day, you will keep the l…
Nomenclature
- Urobilinogen is closely related to two other compounds: mesobilirubinogen and stercobilinogen. Specifically, urobilinogen can be reduced to form mesobilirubinogen, and mesobilirubinogen can be further reduced to form stercobilinogen. Confusingly, however, all three of these compounds are frequently collectively referred to as "urobilinogens".
