Bilirubin is a pigment in bile created during the breakdown of haemoglobin, which is then excreted from the body in bile. It is bilirubin which gives people the characteristic yellow colour in jaundice (whether that be caused by liver failure, obstruction or an increased breakdown of haemoglobin).

What is the medical term meaning high blood bilirubin level?

Why might choledocolithiasis cause jaundice?

well, you see.. jaundice is caused by the elevation of UNCONJUGATED bilirubin level in our blood.. a high level of unconjugated bilirubin in blood will enter our body tissue and make our skin looks yellow.bilirubin is metabolized in the liver, thus making the unconjugated bilirubin changed into conjugated one. and these conjugated bilirubin will be excreted to our intestine and it will give color to our urine an patients with choledocolithiasis, there is an obstruction caused by the gallstone inside the duct where conjugated bilirubin should be excreted.. this obstruction makes the liver unable to metabolize the unconjugated bilirubin, and so the level of unconjugated bilirubin will rise, having effect of jaundice.

What is bilirubin 9 mean?

A total bilirubin of 9 is fine. Some hospitals state it should be under 12, some state it should be under 17. Bilirubin blood test levels are one of those things where "lower is better". (Bilirubin is a byproduct which you liver is supposed to excrete in bile, which is then excreted via your digestive system. If your liver is not excreting bilirubin in bile, your blood bilirubin level increases, showing that your liver isn't quite right.)

What is TBIL on a blood test?

Bilirubin is a breakdown product of heme (a part of haemoglobin in red blood cells). The liver is responsible for clearing the blood of bilirubin. It does this by the following mechanism: bilirubin is taken up into hepatocytes, conjugated (modified to make it water-soluble), and secreted into the bile, which is excreted into the intestine. Increased total bilirubin causes jaundice, and can signal a number of problems: 1. Prehepatic: Increased bilirubin production. This can be due to a number of causes, including hemolytic anemias and internal hemorrhage. 2. Hepatic: Problems with the liver, which are reflected as deficiencies in bilirubin metabolism (e.g. reduced hepatocyte uptake, impaired conjugation of bilirubin, and reduced hepatocyte secretion of bilirubin). Some examples would be cirrhosis and viral hepatitis. 3. Posthepatic: Obstruction of the bile ducts, reflected as deficiencies in bilirubin excretion. (Obstruction can be located either within the liver or in the bile duct.)
