- Bilirubin is a waste product from the breakdown of red blood cells. The liver processes bilirubin so it can be excreted in stool. Bilirubin flows through the liver's bile ducts, dissolved in bile. Bilirubin blood levels may be elevated in people with impaired bile flow.

- Bilirubin. Bilirubin is the main bile pigment that is formed from the breakdown of heme in red blood cells. The broken down heme travels to the liver, where it is secreted into the bile by the liver. Normally, a small amount of bilirubin circulates in the blood.

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).

Overview 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). A common use of the test is to measure bilirubin levels in newborns. 2  Determine whether there might be blockage in your liver's bile ducts.

Bilirubin Bilirubin (formerly referred to as haematoidin and discovered by Rudolf Virchow in 1847) is a yellow compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates. This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged red blood cells.

- Bilirubin that is bound to a certain protein is called unconjugated, or indirect, bilirubin. Conjugated, or direct, bilirubin travels freely through your bloodstream to your liver. Most of this bilirubin passes into the small intestine, but a very small amount passes into your kidneys and is excreted in your urine. This bilirubin also gives urine its distinctive yellow color. This test is usually done to look for liver problems, such as hepatitis, or blockages, such as gallstones.

Bilirubin Blood Test Bilirubin is a yellow pigment that’s in everyone’s blood and stool. Sometimes the liver can’t process the bilirubin in the body. This can be due to an excess of bilirubin, an obstruction, or inflammation of the liver. When your body has too much bilirubin, your skin and the whites of your eyes will start to yellow.

conjugated bilirubin bilirubin. an orange bile pigment produced by the breakdown of heme and reduction of biliverdin; it normally circulates in plasma and is taken up by liver cells and conjugated to form bilirubin diglucuronide, the water-soluble pigment excreted in the bile.ilirubin 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.

Bilirubin - urine Definition. Bilirubin is a yellowish pigment found in bile, a fluid produced by the liver. This article discusses the laboratory test to measure the amount of bilirubin in the urine. Large amounts of bilirubin in the body can lead to jaundice. Bilirubin may also be measured with a blood test.

Bilirubin in Urine If not, the bilirubin circulates the body via red blood cells instead. The bilirubin is excreted as a component of bile, and gives rise to the color of urine and feces through further processing in the small intestine to a component called urobilinogen.

Liver Enzymes and Liver Function Tests and Results Total Bilirubin (T. This lab test measure the total amount of bilirubin in the blood, including direct and indirect bilirubin. Bilirubin is produced during the normal process of blood cells dying and the liver excretes bilirubin through bile. Too much bilirubin in the blood results in the patient looking yellow, or jaundiced.

Why are 30 Million Americans Are Affected by Liver Disease? Bilirubin Tests. Bilirubin is a yellow fluid made in your body when red blood cells break down. A bilirubin test measures the level of bilirubin in your blood. If your liver is damaged, bilirubin can leak out of your liver into your blood and can cause jaundice (yellowing of skin and eyes).

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.wo forms of bilirubin can be measured or estimated by laboratory tests: 1  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.

Jaundice in Adults - Causes, Symptoms, Diagnosis and Treatment Role of Bilirubin in Jaundice. In order to understand jaundice, its causes, types and treatment, we must first understand the function of bilirubin. Bilirubin is a yellow colored substance or waste product that remains after the iron is removed from hemoglobin.
