Bilirubin in Urine
A bilirubin in urine test measures the levels of bilirubin in your urine. Normally, bilirubin isn't found in urine. If there is bilirubin in your urine (called bilirubinuria), it may be an early sign of a liver condition .
What it is for
A bilirubin in urine test is often part of a urinalysis , which may include a visual check of your urine (pee) 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 (which includes your kidneys, ureters, bladder, and urethra). It can also help diagnose liver problems and many other medical conditions. Source: MedlinePlus, National Library of Medicine. Medical test information is public domain.
