Urobilinogen
Understanding Urobilinogen
What is Urobilinogen?
The Urobilinogen test measures the levels of urobilinogen in the urine. The test is often conducted as a part of urine routine and microscopy test and helps assess the health of the liver and detect various health issues, such as liver dysfunction, biliary obstruction, and hemolytic anemia.
Urobilinogen is a byproduct of the breakdown of bilirubin. Bilirubin is initially formed in the spleen and then transported to the liver, where it is chemically modified and excreted into bile. Some of the bilirubin is further broken down in the intestines into urobilinogen, which is then partially reabsorbed into the blood and excreted in the urine. Thus, understanding your urobilinogen levels through the Urobilinogen test helps detect and manage a wide range of disorders.
This test helps in assessing liver health and detecting liver diseases such as hepatitis, obstructive jaundice, and cirrhosis. It can also assist in diagnosing conditions where there is an increased breakdown of red blood cells, such as hemolytic anemia. Additionally, the Urobilinogen test helps monitor the progression of known liver conditions.
Your doctor may recommend this test if you have signs or symptoms of liver disease, such as jaundice, abdominal pain, or abnormal liver function test results. Higher than normal levels may indicate liver diseases such as hepatitis, cirrhosis, or liver damage, or hemolytic diseases where there is increased breakdown of red blood cells. On the contrary, low or absent Urobilinogen levels could suggest bile duct obstruction (cholestasis) or severe liver dysfunction where bilirubin is not adequately converted to urobilinogen.
Fasting is not required for this test. Your doctor may ask you to stop taking certain medications and supplements before the test as they may affect the results. The urine sample should be collected into a sterile container provided by the sample collection professional and women are advised not to give the sample during menstrual period unless prescribed.
Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. Narrate your complete medical history to help the doctor correlate your clinical and laboratory findings. The results will help them determine your medical condition and formulate your treatment plan.
What is Urobilinogen used for?
The Urobilinogen test is done:
- As a part of a urine routine and microscopy test to assess overall health.
- If you have symptoms of liver disease such as nausea, dark colored urine, itchiness of skin and jaundice.
- To assess the functioning of the liver and diagnose liver diseases such as hepatitis, obstructive jaundice, and cirrhosis.
- To diagnose conditions where there is an increased breakdown of red blood cells, such as hemolytic anemia.
What does Urobilinogen measure?
The Urobilinogen test measures the amount of urobilinogen present in the urine. Urobilinogen is a substance formed from the breakdown of bilirubin, a by-product of old red blood cells processed by the liver. This test plays a key role in assessing liver function and detecting liver diseases.
Under normal circumstances, the liver converts bilirubin into urobilinogen. Some of this urobilinogen is reabsorbed into the blood, excreted by the kidneys, and then eliminated from the body through urine. However, when liver function is impaired, the amount of urobilinogen in the urine can change. Hence, the Urobilinogen test serves as an important indicator of abnormalities such as liver disease or blockage of the bile ducts.
Interpreting Urobilinogen results
Interpretations
If the test results indicate low concentration of urobilinogen then it means that there is a barrier in the flow of bile from the liver, there is an obstruction in the flow of blood from the liver or there is some issue with functioning of the liver.
