The Bilirubin Total aids in calculating the level of bilirubin in the blood. A yellowish pigment called bilirubin is created naturally as red blood cells are broken down. It eventually exits the body through excretion after passing through the liver. If you suffer liver disease signs like dark urine, jaundice, or vomiting, you should get this test. The liver function test includes it as a component. Monitoring neonatal jaundice in neonates may also be indicated. It may even be used to show a history of significant alcohol consumption. In cases of jaundice, high bilirubin levels can cause skin and eye yellowing.
