Bilirubin Levels Chart is a table of common bilirubin levels that cause jaundice yellowish color of the skin and eyes sclera, includes normal bilirubin levels, high bilirubin levels, and low bilirubin levels in the same place. Where bilirubin comes from and where bilirubin goes to? Bilirubin comes from degradation of hemoglobin and cells breakdown by spleen or other organs, bilirubin enters blood stream as large insoluble molecule which has the term unconjugated , when reaches the liver, hepatic cells perform chemical reaction to make bilirubin soluble in the blood by bound it to the glucuronic acid by the enzyme glucuronyltransferase which then called conjugated , conjugated bilirubin go from the liver to the intestine and undergoes reduction to the form called stercobilirubin which give the stool its yellowish color, another part of direct bilirubin go to urine through the kidney after being transformed to a compound called urobilinogen urine dye which gives the urine the yellowish color. Low levels of bilirubin are generally not concerning and are not monitored as there is no studies confirm a risk for flow level of bilirubin. Bilirubin results like:.

Bilirubin is a byproduct of red blood cell destruction and are conjugated in the liver and excreted in bile. It is the main pigment which is responsible for the color of bile, feces and urine. If the bilirubin in the blood is too high hyperbilirubinemia , it leads to jaundice or icterus, which is the yellowish discoloration of the skin, sclera, lining of the mouth and other tissues. These blood cells are destroyed when they become fragile or reach the end of their lifespan which is approximately days. When an RBC bursts, it releases hemoblogin into the blood.
Bilirubin Blood Test
A year-old white man presents for evaluation of an asymptomatic elevation in bilirubin detected on a chemistry panel during an annual physical examination. Thirty years ago, he had abnormal liver function tests attributed to use of an unknown medication that resolved when the drug was discontinued. He reports no jaundice, pruritus, or family history of liver disease and takes no medications. His liver was 7. The examination was otherwise unremarkable.
