Bilirubin Direct Serum Test
Bilirubin Direct, Serum Price
Bilirubin is a yellowish pigment found in the red blood cells, which is then broken down and carried by the liver for disposal. This process thus consists of two parts. In the first part after the red blood cells are broken down, the bilirubin is bound to a protein (albumin) in the blood. This is known as unconjugated or direct bilirubin. In the second part, liver then converts bilirubin into a form that can be excreted. This is known as conjugated or direct bilirubin. Bilirubin direct serum is a blood test used to measure the amount of direct bilirubin in the blood.
Direct bilirubin or conjugated bilirubin in the blood serum is indicative of the metabolism of bilirubin and the functioning of the liver. The test is taken to ensure that the individual is healthy and is not at risk of anaemia. Similarly, the test in newborns is taken to assess symptoms of jaundice.
Bilirubin is a yellowish pigment found in the red blood cells (RBC) and is produced when your body breaks down haemoglobin from the aged red blood cells. It is then transported to the liver for disposal. The process of the breakdown takes place in two parts. Firstly, the red blood cells are disintegrated, and the bilirubin produced from the disintegration bounds with the albumin protein in the blood. This is known as conjugated or direct bilirubin.
In the second part, the liver converts bilirubin into a form that can be excreted. Thus, the test of Bilirubin direct serum is conducted to indicate the amount of direct bilirubin in the blood.
