Urobilirubin (BIL)

Bilirubin is a metabolic production of red blood cells after destruction. It can be divided into unconjugated bilirubin without liver treatment and bound bilirubin formed by combination of liver and glucuronic acid. Unbound bilirubin is insoluble in water and does not pass through the glomerular filter in the blood. The combined bilirubin has a small molecular weight and high solubility, and can be discharged from the urine through the glomerular filter membrane. Because the normal human blood combined with bilirubin content is very low, the filtration excess is very small, so bilirubin can not be detected in the urine. For example, the increase of bilirubin in the blood can increase the amount of bilirubin in the urine through the glomerular membrane. Increased, the urine bilirubin test amount was positive.
