As a medical professional with expertise in clinical diagnostics, I can provide you with information on normal bilirubin levels. Bilirubin is a yellow pigment that is a byproduct of the breakdown of red blood cells. It is processed by the liver and excreted in bile. There are two main types of bilirubin: unconjugated (indirect) and conjugated (direct) bilirubin.
Normal bilirubin levels can vary slightly depending on the specific laboratory and the population it serves, but generally, they are as follows:
- Total Bilirubin: The sum of both direct and indirect bilirubin. The normal range for total bilirubin is typically between 0.2 and 1.2 mg/dL (3.4 to 20.5 µmol/L) for adults.
- Direct (Conjugated) Bilirubin: This is the form that has been processed by the liver. The normal range is usually between 0.0 and 0.3 mg/dL (0 to 5.1 µmol/L) for adults.
- Indirect (Unconjugated) Bilirubin: This is the form that has not yet been processed by the liver. The normal range can be slightly higher, typically between 0.0 and 1.0 mg/dL (0 to 17.1 µmol/L) for adults.
It's important to note that these levels can be different for newborns, especially during the first week of life, due to the normal process of neonatal jaundice.

It is normal to have some bilirubin in the blood. A normal level is: Direct (also called conjugated) bilirubin: less than 0.3 mg/dL (less than 5.1 ��mol/L) Total bilirubin: 0.1 to 1.2 mg/dL (1.71 to 20.5 ��mol/L)
