Bilirubin (Total)

Test information: Bilirubin is formed in the reticulo-endothelial system mainly the spleen, when aged erythrocytes are degraded. Haem from haemoglobin and other haem-containing proteins is converted to bilirubin, bound to plasma albumin and transported to the liver (unconjugated or indirect bilirubin). In the liver, it is conjugated with glucuronic acid for solubilisation (conjugated or direct bilirubin) and transported through the bile duct for elimination via the digestive tract. Increased bilirubin in the circulation gives rise to jaundice.
