Indirect bilirubin 33μmol/L is not serious if it is physiologically high, but pathologically high (liver disease, blood disease) is more serious, and the cause of the disease needs to be clarified and treated. The normal range of indirect bilirubin is 1.7-10.2 μmol/L, and a test result of 32 μmol/L is considered high. Physiologic high bilirubin, such as breastfeeding jaundice and physiologic jaundice in newborns, can subside on its own and is usually not serious. Liver diseases, such as acute hepatic necrosis, cirrhosis, chronic active hepatitis, and hepatocellular jaundice are more serious and require treatment. Blood disorders, such as sepsis and hemolytic anemia, can lead to high indirect bilirubin, which is also serious and requires early treatment. If the indirect bilirubin is 33μmol/L, it is recommended to consult a doctor to find out the cause of the disease and follow the doctor’s instructions to avoid delaying the disease.
