Urine is a normal part of our daily lives, and it can tell us a lot about our health. One important component of urine is urobilinogen, which is produced in the liver. Urobilinogen is a by-product of bilirubin, a yellow pigment that is formed when red blood cells break down. Normally, urobilinogen is present in small amounts in the urine.
If there is anything abnormal happening in the body, such as jaundice or a blockage in the bile duct, the levels of urobilinogen in the urine may change. This is because bilirubin cannot be properly metabolized and ends up being excreted in the urine as urobilinogen. Therefore, analyzing the levels of urobilinogen in a urine sample can be used as a diagnostic tool to detect certain liver and gallbladder disorders.
Various tests can be ordered to measure the amount of urobilinogen in the urine. One common test involves collecting a urine sample in a special container and sending it to the laboratory for analysis. The laboratory technicians will then perform tests to determine the urobilinogen levels in the sample.
It is important to note that the presence of urobilinogen in the urine does not always indicate a problem. In fact, low levels of urobilinogen are considered normal. However, consistently high levels of urobilinogen may be an indicator of liver or gallbladder dysfunction. Therefore, if you experience any symptoms such as yellowing of the skin (jaundice) or have concerns about your liver or gallbladder health, it is recommended to consult a healthcare professional who can order the necessary tests to make an accurate diagnosis.
What is it used for
Urobilinogen in urine is used to measure the levels of bilirubin in the body. Bilirubin is a yellow pigment that is produced when red blood cells break down. It is further processed in the liver and eventually excreted through the gallbladder, into the intestines, and then out of the body as part of the feces.
A urine sample can be used to measure the levels of urobilinogen. The presence of urobilinogen in urine can indicate that there is a normal breakdown of red blood cells and that the liver is functioning properly. On the other hand, low levels of urobilinogen in urine can suggest a blockage or problem with the liver or bile ducts, as well as certain diseases such as hepatitis or cirrhosis.
Elevated levels of urobilinogen in urine can be a sign of liver diseases or hemolytic disorders where red blood cells are broken down rapidly. It can also indicate liver dysfunction or bile duct blockages.
Urobilinogen tests are commonly used in medical settings to diagnose and monitor liver and gallbladder function. They can help identify and track the progress of liver diseases and conditions such as hepatitis, alcohol-related liver disease, and obstructive jaundice. They are also used to monitor patients who are taking certain medications that may affect liver function.
It is important to note that urobilinogen tests alone are not enough to make a definitive diagnosis. They are typically used in combination with other tests and clinical evaluations. If you are having any symptoms or concerns related to your liver or gallbladder, it is important to consult with a healthcare professional who can properly evaluate and diagnose them.
Why do I need a urobilinogen in urine test
A urobilinogen in urine test can help diagnose certain conditions related to the liver and gallbladder. Urobilinogen is a substance that forms from the breakdown of bilirubin in the liver. Bilirubin is a yellow pigment that is produced when red blood cells break down. It is responsible for the yellow color of bruises and the brown color of stool. Normally, urobilinogen is present in small amounts in the urine, but an excess amount can suggest liver or gallbladder problems.
Jaundice and hepatitis
One of the main reasons to have a urobilinogen in urine test is to diagnose jaundice. Jaundice is a condition that causes yellowing of the skin and eyes due to high levels of bilirubin in the blood. Urobilinogen in the urine can indicate whether the excessive bilirubin is due to liver disease or other factors, such as hepatitis.
Hepatitis is a viral infection that specifically targets the liver. It can cause inflammation and damage to the liver, leading to increased bilirubin levels. By measuring the urobilinogen in the urine, doctors can determine if hepatitis is the cause of jaundice or if there is another underlying condition.
Gallbladder and bile duct blockage
Gallbladder and bile duct blockage can also be detected through a urobilinogen in urine test. The gallbladder stores bile, a substance that helps digest fats. When there is a blockage in the gallbladder or bile ducts, bile cannot flow properly, leading to an accumulation of bilirubin. This can result in increased urobilinogen levels in the urine.
Doctors may order a urobilinogen in urine test if a patient is experiencing symptoms such as abdominal pain, nausea, vomiting, and yellowing of the skin. The test involves providing a urine sample in a container and sending it to a laboratory for analysis. The results will help doctors make an accurate diagnosis and determine the appropriate treatment.
In conclusion, a urobilinogen in urine test can provide valuable information about liver and gallbladder health. It is used to diagnose conditions such as jaundice, hepatitis, and gallbladder or bile duct blockages. By measuring the amount of urobilinogen in the urine, doctors can identify abnormalities and provide appropriate treatment.
What happens during a urobilinogen in urine test
A urobilinogen in urine test is a simple procedure that can help diagnose certain liver and gallbladder conditions. This test measures the levels of urobilinogen in a urine sample, which is a byproduct of bilirubin breakdown.
To perform this test, a healthcare professional will provide you with a clean container in which to collect your urine sample. It is important to follow their instructions carefully to ensure accurate results.
During the test, you will need to urinate into the container provided. It is essential to avoid contaminating the sample with any toilet paper or other substances. Once you have collected enough urine, you will seal the container and hand it over to the healthcare professional.
The healthcare professional will take the urine sample to a laboratory for analysis. The lab technicians will test the sample to measure the levels of urobilinogen present. Higher or lower levels of urobilinogen may indicate certain conditions or disorders.
A normal urobilinogen level in urine is generally between 0.2 and 1.0 mg/dL. If the test results show higher levels of urobilinogen, it may suggest a problem with the liver or gallbladder, such as hepatitis or a blockage in the bile ducts. On the other hand, lower levels of urobilinogen could indicate an issue with the liver’s ability to break down bilirubin.
In some cases, this test may be part of a larger set of tests used to diagnose a specific condition or evaluate symptoms such as jaundice (yellowing of the skin and eyes). The results of the urobilinogen in urine test, along with other clinical findings, can help healthcare providers determine the best course of treatment.
In conclusion, a urobilinogen in urine test is a valuable diagnostic tool that can provide important insights into liver and gallbladder health. By measuring the levels of urobilinogen in a urine sample, healthcare professionals can identify potential issues and make informed decisions regarding patient care.

Australian National Genomic Information Service (ANGIS), including the database of BioManager, has been maintained for a long time by Peter Reeves, a professor at the University of Sydney.
Professor Reeves is internationally renowned for his genetic analysis of enteric bacteria. He determined the genetic basis of the enormous variation in O antigens. There can be more than an I00 form within a species and little overlap between related species. This variation is due to the reassortment of genes between O antigen genes and other gene clusters and the transfer of gene clusters between species. He showed that the 7th pandemic clone of Vibrio cholerae did not arise directly from the 6th pandemic clone, suggesting it arose from an environmental strain, with implications for the origins of this significant human pathogen.
