The Urobilinogen - Urine test is a diagnostic tool used to measure 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.
When the liver is functioning normally, it converts bilirubin into urobilinogen. Some of this urobilinogen is reabsorbed into the bloodstream, excreted by the kidneys, and then eliminated from the body through urine. However, when liver function is impaired, as in cases of liver disease or blockage of the bile ducts, the amount of urobilinogen in the urine can change. Hence, the urobilinogen - urine test serves as an important indicator of such abnormalities.
This test is non-invasive and does not cause any pain. The only discomfort you might experience is the normal sensation of urinating.
No specific preparation is needed for a urine urobilinogen test. Unless your healthcare provider instructs otherwise, you can eat, drink, and take your medications as usual.
Yes, some medications can affect urobilinogen levels in your urine. These may include certain antibiotics, diuretics, and drugs used to treat tuberculosis (TB). Always inform your healthcare provider about any medications you are taking.
Higher than normal levels of urobilinogen in your urine may suggest a liver disease, such as hepatitis or cirrhosis, or conditions that cause increased destruction of red blood cells. However, additional testing is usually required to confirm these conditions.
Low levels of urobilinogen in the urine can occur when bile ducts are blocked, preventing bilirubin from reaching the intestines where urobilinogen is formed. This could be due to a gallstone or a tumor. In these cases, most of the bilirubin remains in the body and is excreted in the stool, resulting in light-colored or clay-colored stools.
While abnormal levels of urobilinogen can indicate problems with the liver, additional tests are usually needed for a definitive diagnosis. This test serves as an important preliminary tool in the diagnosis process.
While there are home test kits available, it's recommended to have the test done in a clinical lab to ensure the accuracy of the results.
Typically, test results are available within 1 to 2 days. However, the turnaround time can vary depending on the lab.
