A Bilirubin test measures the level of bilirubin in your blood, a yellow pigment produced during the normal breakdown of red blood cells. Your liver helps process and remove bilirubin from the body. Elevated bilirubin levels may indicate liver disorders, bile duct blockage, hepatitis, jaundice, or increased red blood cell destruction. This test is an important marker for evaluating liver function and diagnosing related conditions.

The test typically measures total, direct, and indirect bilirubin to understand how well your liver is working. A small blood sample is taken from a vein, and fasting may be recommended in some cases depending on your doctor’s instructions. This test helps monitor liver diseases, assess jaundice, and evaluate overall liver health.
