Urobilinogen in urine test measures the amount of urobilinogen in a urine sample. Urobilinogen is formed from the reduction of bilirubin. Bilirubin is a yellowish substance found in your liver that helps break down red blood cells. Normal urine contains some urobilinogen. If there is little or no urobilinogen in urine, it can mean your liver isn’t working correctly. Too much urobilinogen in urine can indicate liver diseases such as hepatitis or cirrhosis.
It is done as a part of a regular check-up, to monitor an existing liver condition or if you have symptoms of liver disease which include: Jaundice, nausea, vomiting, dark-colored urine, pain and swelling in the abdomen and/or itchy skin.
A simple urine test can be done in your doctor’s office. You will be asked to pee into a clean cup called a “specimen cup.” Only a small amount of your urine is needed (about two tablespoons) to do the test. The urine is then examined under a microscope.
If your test results show too little or no urobilinogen in your urine, it may indicate:
- A blockage in the structures that carry bile from your liver
- A blockage in the blood flow of the liver
- A problem with liver function
If your test results show a higher-than-normal level of urobilinogen, it may indicate:
- Liver damage due to drugs
- Hemolytic anemia, a condition in which red blood cells are destroyed before they can be replaced. This leaves the body without enough healthy red blood cells
