The liver performs more than 500 vital functions in the human body. It regulates blood levels of amino acids, processes haemoglobin, and helps produce certain proteins for blood plasma, among others.Among all the functions the liver performs, excreting bile is the most crucial function of the liver.Bile is a digestive fluid that aids in the removal of waste and the breakdown of lipids in the small intestine during digestion. The sticky fluid contains bile salts, electrolytes, bile pigments, cholesterol, and other fats. Besides digestion, bile acid helps in the management of cholesterol levels. Bile also removes toxins from the body, aiding liver detoxification.Bilirubin is the primary pigment in bile. This pigment plays a significant role in maintaining bile and liver function. If the bilirubin levels in the body fluctuate, it can pose serious problems.High bilirubin levels may indicate jaundice, abnormal functioning of red blood cells, or cirrhosis. Bilirubin tests are performed to diagnose and monitor liver health and bile duct diseases. You should get a bilirubin test done if you are showing the following symptoms:JaundiceAbdominal discomfort or swellingSwelling of your legs or anklesExhaustionNauseaVomitingGetting bruised easilyDark urinePale, bloody, or dark stoolsItchy skinBilirubin goes through two stages for proper functioning. In the primary stage, bilirubin is transported from the blood into the liver by binding to albumin. In this stage, bilirubin is referred to as indirect or unconjugated bilirubin.In the second phase, sugar molecules are attached to the unconjugated bilirubin to release it into bile upon entering the liver. This is called conjugated or direct bilirubin. While high direct bilirubin can indicate hepatitis, gallstone, appendix, or jaundice, high indirect bilirubin indicates liver issues.Indirect bilirubin levels can rise due to regular strenuous workouts, abnormal red blood cell destruction, liver condition like cirrhosis and fatty liver, gilbert’s syndrome, or some rare genetic disorders. If your doctor suspects any of these conditions, he will advise you to get the Indirect Bilirubin Test.A tiny sample of blood is required for the test.
