Urobilinogen in Urine
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. Your liver uses the bilirubin to make bile, a fluid that helps you digest food in your intestines. Some bile flows through your bile ducts (small tubes) from your liver directly into your intestines. The rest is stored in your gallbladder for when you need it.
What it is for
A urobilinogen in urine test may be part of a urinalysis , a test which may include a visual check of your urine sample, tests for certain chemicals, and an examination under a microscope to look for certain types of cells. A urinalysis is often used to check your general health, including the health of your urinary tract and kidneys. It can also help diagnose diseases that affect the liver and many other medical conditions. Source: MedlinePlus, National Library of Medicine. Medical test information is public domain.
