Elevated levels may indicate liver damage or disease. Higher than normal levels of direct bilirubin in your blood may indicate your liver isn't clearing bilirubin properly. One common, and harmless, cause of elevated bilirubin is Gilbert's syndrome, a deficiency in an enzyme that helps break down bilirubin.
Thereof, what secretes bilirubin?
Bilirubin, a brownish yellow pigment of bile, secreted by the liver in vertebrates, which gives to solid waste products (feces) their characteristic colour. It is produced in bone marrow cells and in the liver as the end product of red-blood-cell (hemoglobin) breakdown.
Is bilirubin excreted in urine or stool?
The bilirubin is recunjugated in the liver and re-excreted in the feces. The reabsorbed urobilinogen is excreted in the urine, about 4 mg/ day and 0,1 to 1 mg in a random urine sample. The bile does not reach the intestine therefore the feces are acholic.
What does it mean to have high bilirubin?
High levels of bilirubin can lead to jaundice. This disorder is easily recognizable due to a yellowing of the skin or eyes. The approximate normal range of bilirubin in the blood serum is: For adults, 1.2 milligrams per deciliter (mg/dL) For children under 18 years, usually 1 mg/dL.
