Bilirubin

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.

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).
