Urobilinogen（Cat No.:M066432）is a colorless byproduct formed in the intestines from the reduction of bilirubin by gut bacteria. It is part of the heme degradation pathway, where hemoglobin from red blood cells is broken down into bilirubin, which is then processed by the liver and excreted into the intestines. Most urobilinogen is reabsorbed into the bloodstream and transported back to the liver, but some is excreted in the urine. Elevated or reduced levels of urobilinogen in urine can indicate liver dysfunction, hemolysis, or biliary obstruction, making it an important marker in medical diagnostics.
