A urobilinogen in urine test measures the amount of urobilinogen in your urine (pee). Urobilinogen comes from bilirubin. Your body makes bilirubin during the normal process of breaking down old red blood cells., Abnormal levels of urobilinogen in urine can signal underlying health issues, often accompanied by specific symptoms that reflect disruptions in the liver, bile ducts, or red blood cell metabolism. Recognizing these signs can help prompt timely medical intervention., High levels of urobilinogen in your urine can indicate liver disease and some types of anemia. Low levels of urobilinogen in your urine may be a sign of liver, gallbladder, or bile duct disease. Urobilinogen is a type of pigment that the colon produces when it breaks down old red blood cells., Elevated urobilinogen urine levels usually stem from one of three main underlying causes: liver disease, hemolytic anemia, or intestinal bleeding. Understanding the possible reasons for too much urobilinogen production helps diagnose medical conditions requiring treatment., Urobilinogen is a byproduct of bilirubin breakdown, and its levels in urine can indicate liver and kidney health. The normal range for urobilinogen in urine is 0.1 to 1.0 mg/dL. Urinalysis, typically done with a dipstick test, measures these levels., Urobilinogen in the urine is the result of bilirubin breakdown, which is metabolized in the gut and partially excreted by the kidneys. Its presence in urine can help your doctor assess liver function and red blood cell functioning, with abnormal levels possibly being a sign of liver disease, hemolysis, or bile duct obstruction..
