Bilirubin Bilirubin is an orange-yellow pigment and a waste product. A bilirubin test may be used to help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia and blockage of the bile ducts.

- Bilirubin testing may be done to: 1  Investigate jaundice — elevated levels of bilirubin can cause yellowing of your skin and the whites of your eyes (jaundice). 2  A common use of the test is to measure bilirubin levels in newborns. 3  Determine whether there might be blockage in your liver's bile ducts.

- If your results on the blood test are higher, bilirubin may also show up in your urine. Urine in adults normally contains only 0.02 mg/dL. Most urine tests will not detect this amount. Results that are higher may mean that you have a liver problem, hepatitis, or gallstones.

- Bilirubin is a yellowish pigment found in bile, a fluid produced by the liver. This article discusses the laboratory test done to measure bilirubin in the blood. Total and direct bilirubin are usually measured to screen for or to monitor liver or gallbladder problems.

Bilirubin A bilirubin test is used to detect an increased level in the blood. It may be used to help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia, and blockage of the bile ducts. Unconjugated bilirubin —when heme is released from hemoglobin, it is converted to unconjugated bilirubin. 2  It is carried by proteins to the liver. 3  Small amounts may be present in the blood. 4  Conjugated bilirubin —formed in the liver when sugars are attached (conjugated) to bilirubin.

Overview Bilirubin testing checks for levels of bilirubin in your blood. Bilirubin (bil-ih-ROO-bin) is an orange-yellow substance made during the normal breakdown of red blood cells. Bilirubin passes through the liver and is eventually excreted out of the body.Higher than normal levels of bilirubin may indicate different types of liver problems. Occasionally, higher bilirubin levels may indicate an increased rate of destruction of red blood cells (hemolysis).1  Why it's done.igher than normal levels of bilirubin may indicate different types of liver problems. Occasionally, higher bilirubin levels may indicate an increased rate of destruction of red blood cells (hemolysis).

Total Bilirubin (Blood) This is a blood test that measures the amount of a substance called bilirubin. This test is used to find out how well your liver is working. It is often given as part of a panel of tests that measure liver function. A small amount of bilirubin in your blood is normal, but a high level may be a sign of liver disease. The liver makes bile to help you digest food, and bile contains bilirubin. Most bilirubin comes from the body's normal process of breaking down old red blood cells. A healthy liver can normally get rid of bilirubin.

Bilirubin Therefore increased serum levels of bilirubin indicate either excessive red blood cell destruction or a problem in the liver that may be inhibiting the normal excretion of bilirubin.Testing for bilirubin is done to screen for or monitor liver disorders or hemolytic anemia. ,herefore increased serum levels of bilirubin indicate either excessive red blood cell destruction or a problem in the liver that may be inhibiting the normal excretion of bilirubin.

- A bilirubin test measures the amount of bilirubin in a blood sample. Bilirubin is a brownish yellow substance found in bile. It is produced when the liver breaks down old red blood cells.

bilirubin bilirubin that has not been conjugated in the liver. It gives an indirect reaction to the van den bergh test. A high level of it in the blood is indicative of hemolysis or a lack of bilirubin clearance by the liver.ilirubin. A pigment produced by the liver that is excreted in bile which causes a yellow discoloration of the skin and eyes when it accumulates in those organs. Bilirubin levels can be measured by blood tests, and are most often elevated in patients with liver disease or a blockage to bile flow.

Understanding Lab Tests: Entire Lesson 1 High levels of bilirubin can cause jaundice (yellowing of the skin and eyes, darker urine, and lighter-colored bowel movements). 2  Elevated bilirubin levels can be caused by reasons other than liver disease.3  Total bilirubin is made up of 2 components: direct bilirubin and indirect bilirubin. When bilirubin levels remain high for prolonged periods, it usually means there is severe liver disease and possibly cirrhosis. 2  High levels of bilirubin can cause jaundice (yellowing of the skin and eyes, darker urine, and lighter-colored bowel movements).

- Normally, a small amount of bilirubin circulates in the blood. Serum bilirubin is considered a true test of liver function, as it reflects the liver's ability to take up, process, and secrete bilirubin into the bile. Bilirubin production and excretion follows a specific pathway.

Bilirubin Bilirubin (formerly referred to as haematoidin) is the yellow breakdown product of normal heme catabolism, caused by the body's clearance of aged red blood cells which contain hemoglobin.Bilirubin is excreted in bile and urine, and elevated levels may indicate certain diseases.ilirubin consists of an open chain of four pyrrole-like rings (tetrapyrrole). In heme, these four rings are connected into a larger ring, called a porphyrin ring. Bilirubin can be conjugated with a molecule of glucuronic acid which makes it soluble in water (see below).

- Elevated levels may indicate hemolytic jaundice, hepatitis, or cirrhosis. The urobilinogen test detects impaired liver function by measuring urine levels of urobilinogen, the colorless, water-soluble product that results from the reduction of bilirubin by intestinal bacteria.levated levels may indicate hemolytic jaundice, hepatitis, or cirrhosis.

- What Do the Results Mean? A bilirubin test measures total bilirubin. It can also give levels of two different types of bilirubin: unconjugated and conjugated. Unconjugated (“indirect”) bilirubin. This is the bilirubin created from red blood cell breakdown. It travels in the blood to the liver. Conjugated (“direct”) bilirubin. This is the bilirubin once it reaches the liver and undergoes a chemical change.

Symptoms of Elevated Bilirubin Elevated levels of bilirubin may indicate that a person is having a problem with their blood count or with their liver function. In addition, infants may also have high bilirubin levels for a few days following birth. The symptoms of elevated bilirubin are similar between adults and children, even if the causes are different.

Medical Dictionary When bilirubin levels are high, the skin and whites of the eyes may appear yellow (jaundice). Jaundice may be caused by liver disease (hepatitis), blood disorders (hemolytic anemia), or blockage of the tubes (bile ducts) that allow bile to pass from the liver to the small intestine.he bilirubin test is used to: 1  Check liver function and watch for signs of liver disease, such as hepatitis or cirrhosis, or the effects of medicines that can damage the liver. 2  Find out if something is blocking the bile ducts. 3  This may occur if gallstones, tumors of the pancreas, or other conditions are present.

Elevated Bilirubin Levels: Overview Elevated Bilirubin Levels. Elevated Bilirubin Levels: Overview. Bilirubin is produced when the liver breaks down old red blood cells. The levels of bilirubin in the body are normally low, so elevated levels may indicate certain diseases such as those that impair liver function, bock bile ducts, or cause increased destruction of red blood cells.

Bilirubin Bilirubin is excreted in bile and urine, and elevated levels may indicate certain diseases. It is responsible for the yellow color of bruises and the yellow discoloration in jaundice. Its subsequent breakdown products, such as stercobilin, cause the brown color of feces. A different breakdown product, urobilin, is the main component of the straw-yellow color in urine.

What does it mean when your BILIRUBIN LEVELS are too high? Elevated bilirubin can be a sign of liver disease, gallstones stuck in a duct, or destruction of red blood cells. In general, the higher it is, the worse it is. Important to keep in mind, however, that there are a lot of folks running around with slightly elevated bilirubin levels who aren't in the slightest bit sick.
