Urobilinogen is a colorless byproduct of bilirubin reduction by intestinal bacteria. Most is excreted in feces, but a small amount is reabsorbed and excreted by the kidneys. Testing for urobilinogen in urine is a key step in differentiating between types of jaundice and assessing liver function or hemolytic disorders.

Why Context Matters

Urobilinogen is highly unstable; if a urine sample sits in light or at room temperature for too long, it oxidizes to urobilin, leading to a false-negative result. Results can also be influenced by urine pH and antibiotic use.

Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
