What is the Normal Range of Bile Pigment Levels?

Biliverdin, also known as bilirubin, can refer to total bilirubin, direct bilirubin, and indirect bilirubin. The normal reference range for total bilirubin is generally between 1.7-17.1μmol/L, the normal reference range for direct bilirubin is generally between 0-6.8μmol/L, and the normal reference range for indirect bilirubin is generally between 1.7-10.2μmol/L.

Firstly, the increase in total bilirubin and direct bilirubin is commonly associated with intrahepatic and extrahepatic obstructive jaundice, pancreatic cancer, cholangitis, and other bile duct obstruction syndromes.

Secondly, the elevation of total bilirubin and indirect bilirubin is often caused by hemolytic anemia, blood type incompatibility, blood transfusion, malignant diseases, neonatal jaundice, and other reasons.

Thirdly, when total bilirubin, direct bilirubin, and indirect bilirubin are all elevated, it is commonly due to acute icteric hepatitis, chronic active hepatitis, cirrhosis, and toxic hepatitis.

If symptoms are severe, it is recommended to seek medical attention promptly for examination and treatment. Avoid spicy and stimulating foods, and ensure adequate sun exposure and hydration to facilitate a speedy recovery.
