A normal bilirubin level in blood typically falls between 0.1 to 1.2 mg/dL (1.71 to 20.5 µmol/L) for total bilirubin and less than 0.3 mg/dL (less than 5.1 µmol/L) for direct bilirubin. It's important to note that different labs may have slightly varying ranges for what they consider normal.
Bilirubin is a yellowish pigment that's produced during the breakdown of red blood cells. The liver processes bilirubin and excretes it in bile. High levels of bilirubin in the blood can indicate liver disease, while low levels may be related to certain types of anemia.
