Bilirubin (formerly referred to as haematoidin) is the yellow breakdown product of normal heme catabolism, caused by the body's clearance of aged red blood cells which contain hemoglobin. Bilirubin is excreted in bile and urine, and elevated levels may indicate certain diseases.
A complete urinalysis evaluates several different aspects of your urine through physical, chemical, and microscopic examination. In lupus treatment, a urinalysis is often used to monitor protein leakage and identify and assess urinary tract infections (UTIs). Bilirubin: Bilirubin is made by the liver from old red blood cells; it is then processed by the intestine and excreted from the body. 2  Therefore, healthy individuals do not have bilirubin in their urine. 3  The presence of bilirubin in the urine indicates that the liver is allowing the substance to leak back into the blood.
