Indirect bilirubin of 13 μmol/L is considered mildly elevated.
Indirect bilirubin is formed when aging red blood cells in the blood are broken down and destroyed in the liver, spleen and bone marrow, releasing hemoglobin, which is metabolized in the body and combined with plasma albumin.
The normal range of indirect bilirubin is 1.7-10.2 umol/L. A test result of 13 μmol/L is mildly high, and the normal range of measurement may vary due to the different reagents used in each hospital.
The value of indirect bilirubin reflects the function of liver cell damage and the state of red blood cell breakdown. High indirect bilirubin may be the result of acute jaundice hepatitis, acute hepatic necrosis, hemolytic jaundice, and hepatocellular jaundice.
With an indirect bilirubin of 13 μmol/L, it is recommended to seek medical attention to identify the cause of the disease and treat it as soon as possible.
