Question: what is the difference between conjugated bilirubin and unconjugated bilirubin?
Answer: Bilirubin that is bound to a certain protein (albumin) in the blood is called unconjugated, or indirect, bilirubin. Conjugated, or direct, bilirubin travels from the liver into the small intestine. A very small amount passes into your kidneys and is excreted in your urine.
